The 1936 Municipal Hall: Conservation Decisions Under Pressure
A 1936 neoclassical municipal hall stands on a 3,000 m2 corner lot in a provincial capital. It has a 1,150 m2 footprint over two floors plus a raised basement, and was declared an Important Cultural Property in 2019. The new owner, a retail developer, wants ground-floor retail, offices above and a food court in the basement. The condition survey reports: 40% of the cornice spalled with exposed, corroded reinforcement; 70% of the original steel casement windows seized or missing; a structurally independent 1995 rear annex in fair condition; a grand stair rising 1.35 m from the sidewalk to the main floor; and one central 1.4 m-wide stair as the only vertical circulation. A 2022 typhoon took down 12 m of roof parapet, which the owner proposes to rebuild as a plain concrete wall.
1. The owner wants to strip the remaining cornice and rebuild it as a simplified concrete band 'in the same spirit' to save money. How do you advise, and what do you require before any work starts?

Separate the three questions the owner is blurring: significance, treatment, and process.
- Significance. The cornice is part of the original 1936 fabric and its continuous profile is what reads as neoclassical at street level. That is the element that carries the character. The 60% still in place is irreplaceable evidence; once stripped, the building can only ever be a copy of itself.
- Treatment. Conservation practice ranks options from least to most intervention: repair and consolidate, then restore, then reconstruct, then replace with new work. A 'simplified concrete band in the same spirit' is pastiche - it is neither honest restoration (it is not the original profile) nor honest new work (it pretends to be old). It is the worst of both.
- Process. As a declared Important Cultural Property, the building is covered by R.A. 10066; any modification needs prior written authorization from the heritage authority and, in most LGUs, clearance from the local heritage council before a building permit is processed. Advise the owner in writing that proceeding without that clearance exposes the project to a stop-work order.
Recommended course: commission a structural assessment of the remaining cornice before touching it - much spalled cornice is repairable by removing loose concrete, treating the rebar, and rebuilding the profile with matched repair mortar on stainless anchors. Where sections are lost, replicate the profile in a compatible material but date the intervention in the conservation record. For the parapet, design a clearly contemporary element that reads as new, or rebuild the profile with a documented justification. Tell the owner plainly that the cost saving is real but small relative to the retail value of a genuine heritage address - and that the irreversible loss is his to own, in writing.
2. The main floor sits 1.35 m above the sidewalk and is reached only by the grand stair. Resolve the accessibility requirement without destroying the entry composition.

The arithmetic first. At the BP 344 maximum slope of 1:12, a 1.35 m rise needs 16.2 m of run, plus landings at top, bottom and at intermediate intervals, at 1.20 m clear width with handrails on both sides. A single 16 m ramp straight up the front will bury the facade and the grand stair. So the question is not 'where do I put the ramp' but 'which access strategy costs the composition least'.
Options, ranked:
- Regrade the forecourt. If the sidewalk level can be raised or the site cut back so the entry threshold sits within 150–200 mm of grade, a short ramp or level landing solves it and the grand stair becomes symbolic rather than functional. Usually the cheapest and least visible.
- Ramp on the side elevation running parallel to the facade, returning to a secondary entry door into the same lobby. Buries a blank wall rather than the composition, and can be detailed as a contemporary element.
- Platform lift at the side entry, where run is impossible. Legitimate under BP 344 but needs maintenance and a power supply - flag the operational risk to the owner, since a lift that fails makes the building non-compliant in practice.
- Ramp up the centre is the option to refuse.
Whatever is chosen, the accessible route must reach the same entrance, the same lobby, the basement food court (elevator, not just the stair) and the toilet facilities - compliance at the front door with non-compliance inside is not compliance. Put the decision and the reasoning in a signed memo so the choice is recorded as a design decision, not an oversight.
3. The tenant mix needs a second stair, an elevator and a service core. Where do you put the new vertical circulation, and what governs the decision?
Read the worked answer
Two criteria govern: life safety (non-negotiable) and fabric impact (negotiable).
- Egress. A single 1.4 m central stair cannot serve retail at this floor area and occupancy once the basement food court and upper-floor offices are counted. The second means of escape and the fire-rated enclosure are code requirements, not options. Confirm exit widths and travel distances against R.A. 9514 and its IRR with the local fire marshal before fixing the plan - the numbers depend on occupant load, sprinkler protection and whether the stair is pressurised.
- Fabric impact. The 1995 rear annex is structurally independent and of no heritage value. That is where the new core belongs: new stairs, elevator, service riser and the accessible vertical route go into the annex, which can be gutted and rebuilt around them. The historic plan stays legible, the intervention is reversible, and the new work is visibly new. If the annex cannot carry the loads, add a new core outside the historic footprint and link with a glazed joint so the two periods read separately.
- What not to do: do not punch the elevator shaft through the historic hipped roof or the central hall - that is the one move that destroys the spatial sequence the building is valued for.
Deliverable: a conservation-and-egress drawing set that shows existing fabric, new fabric and demolished fabric in three distinct graphic conventions, with the fire-rated enclosure and the protected escape route marked, submitted together with the heritage authority application so the two approvals do not contradict each other.
