Question 1Interior design: spatial proposals, use and tested visual decisions

In interior design, the three primary enclosing surfaces of an interior space are:

  1. Wall, floor and ceiling Correct answer.
  2. Door, window and column
  3. Beam, slab and foundation
  4. Cornice, skirting and architrave

Explanation

An interior space is defined by its enclosing surfaces: walls, floor and ceiling. Layout decisions, finishes and lighting all respond to these three planes.

Question 2Interior design: spatial proposals, use and tested visual decisions

The primary goal of functional interior layout (διάταξη) is to:

  1. Arrange furniture and circulation so activities can be performed safely and efficiently Correct answer.
  2. Maximise the number of decorative objects on every surface
  3. Match wall colour to the exterior façade only
  4. Eliminate all natural light to control glare

Explanation

Functional layout places furniture, equipment and circulation paths so users can complete intended activities with clear access, safe clearances and logical adjacency.

Question 3Interior design: spatial proposals, use and tested visual decisions

In a residential kitchen work triangle, the three points that should form an efficient work path are typically:

  1. Sink, cooker (hob) and refrigerator Correct answer.
  2. Table, sofa and television
  3. Bathtub, WC and washbasin
  4. Wardrobe, bed and desk

Explanation

The classic kitchen work triangle links the sink, cooking appliance and refrigerator - the three stations used most during meal preparation - so walking distance stays short and unobstructed.

Question 4Interior design: spatial proposals, use and tested visual decisions

When planning a bathroom layout, which clearance principle is most important around a WC?

  1. Leave clear frontal approach space so a person can sit and stand without obstruction Correct answer.
  2. Place the WC hard against the bathtub rim with no gap
  3. Centre the WC under a low sloping roof where headroom is under 1.5 m
  4. Block the WC door swing with a tall cabinet

Explanation

A WC needs clear frontal and lateral approach space so users can sit, stand and clean around the fixture. Crowding it against other fixtures or under low headroom creates unsafe and unusable layouts.

Question 5Interior design: spatial proposals, use and tested visual decisions

In an open-plan living–dining layout, the dining table should ideally be placed so that:

  1. Circulation between kitchen, dining and living remains continuous and unobstructed Correct answer.
  2. It completely blocks the path from the entrance to the living sofa
  3. Chairs have zero pull-out clearance on all sides
  4. It sits directly in front of the only escape door

Explanation

Dining placement should preserve continuous circulation between kitchen, dining and living zones. Blocking escape routes or chair pull-out space creates both functional and safety failures.

Question 6Interior design: spatial proposals, use and tested visual decisions

For a double bedroom layout, the bed is usually oriented so that:

  1. There is access along at least one long side and clearance at the foot for dressing and cleaning Correct answer.
  2. Both long sides are hard against walls with no walking space
  3. The headboard blocks the only bedroom door
  4. The bed fills the entire floor leaving no wardrobe approach

Explanation

A workable bedroom needs side and/or foot clearances for making the bed, dressing and cleaning. Trapping the bed against walls or doors destroys usable circulation.

Question 7Interior design: spatial proposals, use and tested visual decisions

Which adjacency is generally preferred when planning a compact apartment?

  1. Kitchen near the dining or living eating area to shorten serving paths Correct answer.
  2. Bathroom as far as possible from any water supply stack
  3. Bedroom as the only room with no window and no ventilation
  4. Entrance door opening directly onto a cooktop with no buffer

Explanation

Placing kitchen near dining/living eating space shortens serving and clearing paths and supports functional zoning. Wet rooms still need proper plumbing adjacency and bedrooms need light and ventilation.

Question 8Interior design: spatial proposals, use and tested visual decisions

In kitchen planning, continuous countertop runs between sink and hob primarily support:

  1. Safe food preparation and transfer without long unprotected carries Correct answer.
  2. Hiding the refrigerator completely from view
  3. Eliminating the need for any task lighting
  4. Replacing building structure with furniture only

Explanation

A continuous worktop between wet and cooking zones lets users prepare and transfer food safely without long unprotected carries across circulation paths.

Question 9Interior design: spatial proposals, use and tested visual decisions

Circulation width in a residential corridor should primarily allow:

  1. Two people to pass or one person with a carried item without scraping walls Correct answer.
  2. Only sideways shuffling with furniture filling both sides
  3. Zero clearance for doors to open fully
  4. Permanent storage of ladders in the walking path

Explanation

Corridor clearances must let people pass and move belongings without scraping finishes. Furniture or storage in the walking path creates hazards and wear.

Question 10Interior design: spatial proposals, use and tested visual decisions

When arranging a living-room seating group, the coffee table is typically placed so that:

  1. It sits within comfortable reach of the main seating without blocking primary walkways Correct answer.
  2. It completely fills the space between sofa and exit door
  3. It is fixed to the ceiling as a hanging element
  4. It replaces all floor lamps as the only light source

Explanation

Coffee tables serve seated users within arm’s reach while leaving clear walkways around the seating group. Blocking exits or treating them as lighting is incorrect.

Question 11Interior design: spatial proposals, use and tested visual decisions

In bathroom planning, placing the washbasin near the entrance of the wet zone most often helps because:

  1. It supports quick handwashing and grooming without crossing wet shower spray zones first Correct answer.
  2. It guarantees zero ventilation is needed
  3. It removes the need for waterproofing anywhere
  4. It allows electrical sockets inside the shower tray

Explanation

A basin near the bathroom entry supports frequent handwashing and grooming while keeping shower spray and wet floors more contained. Waterproofing and safe electrical zoning remain mandatory.

Question 12Interior design: spatial proposals, use and tested visual decisions

Functional zoning of an interior typically separates:

  1. Noisy/active areas from quiet/rest areas where possible Correct answer.
  2. Every room into identical multifunctional cubes with no hierarchy
  3. Only exterior façades from landscaping
  4. Structural columns from foundations only

Explanation

Zoning groups compatible activities - for example living/dining away from bedrooms - to reduce noise conflict and support comfort. Identical undifferentiated rooms ignore activity needs.

Question 13Interior design: spatial proposals, use and tested visual decisions

In a restaurant or cafeteria layout (recreation/hospitality spaces), table spacing should primarily ensure:

  1. Staff and guests can circulate with trays without constant collisions Correct answer.
  2. Tables are packed edge-to-edge with no aisle
  3. All chairs back tightly against fire exit doors
  4. Kitchen deliveries cross through every dining aisle

Explanation

Hospitality layouts need aisle widths that let staff and guests move with trays safely. Packing tables to block exits or forcing deliveries through dining aisles creates service and safety failures.

Question 14Interior design: spatial proposals, use and tested visual decisions

An office interior layout that places workstations directly in a busy public reception thoroughfare most likely fails because:

  1. Constant interruption and noise reduce concentration and privacy Correct answer.
  2. Workers will have too much natural light
  3. Desks will never need power or data
  4. Fire exits become easier to identify

Explanation

Workstations in public thoroughfares suffer noise, interruption and poor acoustic/visual privacy. Productive office planning separates focused work from public circulation.

Question 15Interior design: spatial proposals, use and tested visual decisions

When a floor plan shows a door swing drawn as a quarter-circle arc, that symbol primarily communicates:

  1. The direction and clearance needed for the door leaf to open Correct answer.
  2. The structural load of the wall above
  3. The colour of the door finish
  4. The exact timber species of the door

Explanation

The quarter-circle door swing shows opening direction and the floor clearance the leaf requires - critical for checking furniture conflicts and egress.

Question 16Interior design: spatial proposals, use and tested visual decisions

In interior colour theory, hues described as 'cool' (such as blues and greens) typically tend to:

  1. Make a space feel calmer and visually recede Correct answer.
  2. Always increase appetite and aggression
  3. Eliminate the need for any artificial light
  4. Convert sound into heat automatically

Explanation

Cool hues are commonly associated with calmness and visual recession, helping small rooms feel less crowded when used thoughtfully on walls.

Question 17Interior design: spatial proposals, use and tested visual decisions

Warm colours such as reds, oranges and yellows are often used in interiors when the designer wants to:

  1. Create a sense of energy, intimacy or visual advance of surfaces Correct answer.
  2. Guaranteed reduce measured room temperature by 10°C
  3. Make all surfaces acoustically absorbent
  4. Replace structural fire protection

Explanation

Warm hues advance visually and are associated with energy and intimacy, so they are used where a lively or cosy atmosphere is desired.

Question 18Interior design: spatial proposals, use and tested visual decisions

A complementary colour scheme places colours that are:

  1. Opposite each other on the colour wheel for strong contrast Correct answer.
  2. Always identical tints of one hue only
  3. Random paints with no relationship
  4. Only metallic finishes with no hue

Explanation

Complementary schemes pair opposites on the colour wheel (for example blue–orange), giving high contrast that must be balanced carefully in interiors.

Question 19Interior design: spatial proposals, use and tested visual decisions

An analogous colour scheme uses colours that are:

  1. Adjacent on the colour wheel for a harmonious, low-contrast look Correct answer.
  2. Exactly opposite on the colour wheel
  3. Limited to black and white only
  4. Always fluorescent safety colours

Explanation

Analogous schemes pick neighbouring hues (for example blue–blue-green–green) for harmony and softer transitions across walls and soft finishes.

Question 20Interior design: spatial proposals, use and tested visual decisions

Painting a low ceiling a lighter colour than the walls most often aims to:

  1. Make the ceiling appear higher and the room less oppressive Correct answer.
  2. Make the ceiling appear to drop visually
  3. Hide all structural cracks permanently without repair
  4. Increase measured humidity automatically

Explanation

Lighter ceilings reflect more light and visually recede, which can make a low ceiling feel higher. Darker ceilings do the opposite.

Question 21Interior design: spatial proposals, use and tested visual decisions

Using a strong accent colour on one feature wall while keeping other walls neutral primarily:

  1. Creates focal hierarchy without overwhelming the whole room Correct answer.
  2. Removes the need for furniture
  3. Guarantees perfect acoustic privacy
  4. Replaces all natural light sources

Explanation

A single accent wall creates a focal point and hierarchy while neutral fields keep the room calm - a common practical colour strategy.

Question 22Interior design: spatial proposals, use and tested visual decisions

Psychological colour associations used in interiors should be treated as:

  1. Useful tendencies that still depend on culture, light and context Correct answer.
  2. Absolute laws identical for every person and culture
  3. Proof that colour has no effect on mood
  4. A substitute for accessibility contrast requirements

Explanation

Colour–mood links (calm blues, energetic reds) are useful design tendencies, but responses vary with culture, lighting and personal experience. Accessibility contrast still matters separately.

Question 23Interior design: spatial proposals, use and tested visual decisions

In a small narrow room, painting the end wall a slightly deeper hue than the long side walls can help to:

  1. Visually shorten the tunnel effect by advancing the far wall Correct answer.
  2. Physically move the wall structure closer
  3. Eliminate the need for any furniture scale checks
  4. Convert the room into outdoor space

Explanation

A deeper colour on the far wall advances visually, helping counter the tunnel-like elongation of a narrow room. Structure itself does not move.

Question 24Interior design: spatial proposals, use and tested visual decisions

High-chroma, highly saturated colours across all four walls of a small bedroom most commonly risk:

  1. Visual fatigue and a feeling of enclosure Correct answer.
  2. Automatic soundproofing of the room
  3. Removing all heat from the space
  4. Eliminating the need for window coverings legally

Explanation

Intense saturated colour on all enclosing planes can feel enclosing and tiring in small rest spaces. Soft or balanced schemes are usually more restful for bedrooms.

Question 25Interior design: spatial proposals, use and tested visual decisions

When selecting interior colours under artificial lighting, designers should remember that:

  1. Lamp colour temperature and CRI can shift how paints and fabrics appear Correct answer.
  2. All lamps render every colour identically to daylight
  3. Colour appearance is independent of light source
  4. Only fluorescent tubes can show true colour

Explanation

Light source correlated colour temperature and colour rendering index change how finishes look. Samples should be checked under the planned lighting, not only under shop daylight.

Question 26Interior design: spatial proposals, use and tested visual decisions

Ergonomic furniture dimensions are important because they:

  1. Are chosen only for decorative pattern matching
  2. Match human body sizes and comfortable reach/use ranges Correct answer.
  3. Ignore user age and ability entirely
  4. Replace building codes for structure

Explanation

Ergonomics sizes furniture to human dimensions - seat height, table height, reach ranges - so use is comfortable and safe for intended users.

Question 27Interior design: spatial proposals, use and tested visual decisions

A typical dining table surface height for seated adults is approximately:

  1. 300–350 mm
  2. 720–760 mm Correct answer.
  3. 1100–1200 mm
  4. 150–200 mm

Explanation

Standard dining tables are roughly 720–760 mm high so seated adults can eat comfortably with elbows near table height. Coffee tables and standing counters sit at different heights.

Question 28Interior design: spatial proposals, use and tested visual decisions

A typical seat height for a dining chair (top of seat to floor) is approximately:

  1. 200–220 mm
  2. 430–460 mm Correct answer.
  3. 700–750 mm
  4. 900–1000 mm

Explanation

Dining seat heights around 430–460 mm pair with standard table heights so thighs clear under the apron and feet rest on the floor.

Question 29Interior design: spatial proposals, use and tested visual decisions

When drawing a piece of furniture for an interior project, an elevation primarily shows:

  1. A horizontal cut through the piece looking down
  2. A vertical face of the piece with true heights and widths as seen from one side Correct answer.
  3. Only the screw catalogue numbers
  4. The structural foundation of the building

Explanation

Elevations show vertical faces - front, side or rear - with true heights and widths. Plans look down; sections cut through.

Question 30Interior design: spatial proposals, use and tested visual decisions

A furniture section drawing is most useful for showing:

  1. Only the exterior paint brand name
  2. Internal construction, thicknesses and how parts join through a cut plane Correct answer.
  3. Site contour lines of the plot
  4. Electrical grid capacity of the city

Explanation

Sections cut through the object to reveal thicknesses, cavities, joinery and layered construction that elevations cannot show.

Question 31Interior design: spatial proposals, use and tested visual decisions

Freehand sketching of furniture during early design is mainly used to:

  1. Replace all final construction documents legally
  2. Explore form and proportion quickly before precise instrument drawings Correct answer.
  3. Measure exact millimetre tolerances for CNC only
  4. Certify structural fire ratings

Explanation

Freehand sketches let designers explore form and proportion rapidly. Final scaled instrument drawings (and/or CAD) then fix dimensions for making and examination presentation.

Question 32Interior design: spatial proposals, use and tested visual decisions

When drawing furniture to scale with geometric instruments, the scale rule (κλιμακόμετρο) is used to:

  1. Cut timber boards to length
  2. Convert real dimensions to correctly sized lines on the drawing sheet Correct answer.
  3. Mix paint pigments
  4. Test acoustic absorption coefficients

Explanation

A scale rule maps real millimetres to the chosen drawing scale (for example 1:20 or 1:10) so furniture drawings are proportionally accurate.

Question 33Interior design: spatial proposals, use and tested visual decisions

Clearance behind a dining chair when pulled out for seating is important to:

  1. Prove the chair has no mass
  2. Allow a person to sit and stand without striking a wall or another diner Correct answer.
  3. Eliminate the need for any table
  4. Replace fire exit width requirements

Explanation

Chair pull-out clearance keeps dining usable. Without it, diners cannot sit comfortably and may hit walls or other seats.

Question 34Interior design: spatial proposals, use and tested visual decisions

Kitchen base cabinet worktop depth in residential practice is commonly about:

  1. 200 mm
  2. 600 mm Correct answer.
  3. 1200 mm
  4. 150 mm

Explanation

Standard base cabinet worktops are commonly about 600 mm deep, balancing usable work surface with reach and kitchen circulation.

Question 35Interior design: spatial proposals, use and tested visual decisions

An adjustable office chair with lumbar support primarily improves ergonomics by:

  1. Removing the need for any desk
  2. Supporting the lower back curve and allowing users of different sizes to sit correctly Correct answer.
  3. Guaranteeing silence in open offices
  4. Acting as a structural column

Explanation

Lumbar support and adjustability help maintain spinal posture across different body sizes during prolonged sitting.

Question 36Interior design: spatial proposals, use and tested visual decisions

When specifying furniture for a children’s bedroom, ergonomic priority should include:

  1. Adult bar-stool heights only
  2. Heights and edges suited to smaller users and safety against sharp corners Correct answer.
  3. Industrial warehouse racking as the only storage
  4. Furniture that blocks all windows permanently

Explanation

Children’s furniture should match smaller body sizes and reduce injury risk from sharp edges and instability. Adult or industrial pieces often fail those needs.

Question 37Interior design: spatial proposals, use and tested visual decisions

On a side elevation of a sofa drawn to scale, which dimension is shown most directly?

  1. Only the fabric weave microscopic structure
  2. Overall height and depth (or length, depending on the side viewed) Correct answer.
  3. Soil bearing capacity under the building
  4. City zoning FAR values

Explanation

A side elevation shows the sofa’s vertical profile - typically overall height and depth - at the chosen scale. Microscopic fabric structure and site engineering data belong elsewhere.

Question 38Interior design: spatial proposals, use and tested visual decisions

Natural solid timber used as an interior finish is valued mainly for:

  1. Being completely fireproof in all thicknesses without treatment
  2. Warm appearance, workability and renewable character when responsibly sourced Correct answer.
  3. Having zero movement with humidity changes
  4. Conducting electricity better than copper

Explanation

Solid timber offers warmth and workability and can be renewable if responsibly sourced. It still moves with moisture and needs fire consideration - it is not a copper-like conductor.

Question 39Interior design: spatial proposals, use and tested visual decisions

Engineered wood products (such as plywood or MDF) are classed as artificial/processed timber materials because they:

  1. Grow as a single tree trunk without processing
  2. Are manufactured by bonding wood fibres, veneers or particles into panels Correct answer.
  3. Are pure metals rolled into sheets
  4. Are natural uncut stone slabs

Explanation

Engineered wood is factory-made from veneers, particles or fibres bonded into stable panels - distinct from solid natural lumber sawn from logs.

Question 40Interior design: spatial proposals, use and tested visual decisions

Marble as an interior surface material is typically chosen for:

  1. Being the lightest soft-touch textile available
  2. Decorative veining and a sense of prestige on floors, walls or vanity tops Correct answer.
  3. Its ability to replace all window glass for transparency
  4. Perfect flexibility like rubber sheet

Explanation

Marble’s veining and polished appearance make it a prestige finish for floors, cladding and vanity tops. It is a hard stone, not a textile, glass substitute or rubber.

Question 41Interior design: spatial proposals, use and tested visual decisions

Granite interior surfaces are often preferred where the brief needs:

  1. A soft upholstery feel for seating
  2. High hardness and good resistance to abrasion and heat on worktops Correct answer.
  3. Transparent daylight admission like clear glass
  4. Acoustic foam behaviour

Explanation

Granite is a hard igneous stone valued for durable, heat-resistant worktops and heavy-wear floors. It is not upholstery, glazing or acoustic foam.

Question 42Interior design: spatial proposals, use and tested visual decisions

Natural stone (πέτρα) cladding indoors should be detailed with attention to:

  1. Only the stone’s marketing brochure colour name
  2. Weight, fixing method, moisture and joint movement Correct answer.
  3. Eliminating all wall substrates
  4. Using no mechanical or adhesive support ever

Explanation

Stone is heavy and needs correct substrates, fixings, moisture management and movement joints. Colour names alone do not ensure a safe installation.

Question 43Interior design: spatial proposals, use and tested visual decisions

Metals used in interiors (steel, aluminium, brass) commonly provide:

  1. Soft cushioning equal to foam upholstery
  2. Strength for frames, trims and fittings with a range of surface finishes Correct answer.
  3. The same thermal softness as thick wool carpets
  4. Zero reflectivity under all lighting

Explanation

Metals give strength and crisp detailing for frames, ironmongery and trims, with finishes from brushed to polished. They are not soft cushioning materials.

Question 44Interior design: spatial proposals, use and tested visual decisions

Glass in interior applications is frequently used to:

  1. Act as the primary soft seating surface
  2. Admit light, create visual connection and protect as screens or shelves Correct answer.
  3. Replace all load-bearing concrete columns without engineering
  4. Absorb all sound better than heavy curtains

Explanation

Interior glass partitions, shelves and screens bring light and visual connection while providing separation. Soft seating, structure and top acoustic absorption use other materials.

Question 45Interior design: spatial proposals, use and tested visual decisions

Gypsum board (γυψοσανίδα) is widely used in interiors because it:

  1. Is a structural replacement for reinforced concrete beams
  2. Creates smooth wall and ceiling linings quickly over framing Correct answer.
  3. Is completely waterproof in untreated wet zones without systems
  4. Conducts hot water as a plumbing pipe

Explanation

Gypsum board provides fast, smooth linings on metal or timber framing. Wet areas need appropriate boards/systems; it is not a concrete beam or water pipe.

Question 46Interior design: spatial proposals, use and tested visual decisions

When comparing materials for a kitchen worktop, the most relevant performance criteria usually include:

  1. Only the loudness of the delivery truck
  2. Stain resistance, heat tolerance, hygiene and durability Correct answer.
  3. Whether the material can grow as a plant indoors
  4. How well it floats as a boat hull

Explanation

Kitchen worktops face stains, heat, cleaning chemicals and abrasion - so those performance criteria drive material choice (stone, laminate, solid surface, etc.).

Question 47Interior design: spatial proposals, use and tested visual decisions

A material’s contribution to the final decorative result mainly comes from its:

  1. Molecular weight listed only in chemistry exams
  2. Colour, texture, pattern, reflectance and how joints are expressed Correct answer.
  3. Ability to erase architectural drawings
  4. Distance from the nearest airport

Explanation

Decoration reads through colour, texture, pattern, sheen and joint expression. Those sensory qualities shape the finished atmosphere.

Question 48Interior design: spatial proposals, use and tested visual decisions

Particleboard used for furniture carcasses should be protected from prolonged wetting because:

  1. It becomes stronger than steel when wet
  2. It can swell, lose strength and degrade at edges when moisture enters Correct answer.
  3. Water turns it permanently into glass
  4. Moisture has no effect on wood-based panels

Explanation

Particleboard is moisture-sensitive: prolonged wetting causes swelling, edge failure and loss of strength. Edging and dry use conditions matter.

Question 49Interior design: spatial proposals, use and tested visual decisions

Stainless steel is often specified for commercial kitchen fittings because it:

  1. Absorbs grease permanently into the metal grain
  2. Resists corrosion and cleans hygienically under frequent washing Correct answer.
  3. Cannot be formed into sinks or benches
  4. Behaves identically to untreated mild steel outdoors

Explanation

Stainless steel’s corrosion resistance and cleanability suit hygienic commercial kitchens. Mild steel rusts more readily without protection.

Question 50Interior design: spatial proposals, use and tested visual decisions

Choosing a soft textile upholstery instead of hard timber for a seating surface primarily changes:

  1. The building’s foundation depth requirement
  2. Comfort, acoustic absorption and tactile warmth Correct answer.
  3. The legal land title of the property
  4. The structural wind load on the roof

Explanation

Upholstery increases sitting comfort, softens sound and feels warmer to touch compared with hard timber seats. It does not change foundations, titles or roof wind loads.
