Landed property interior design in Singapore
for terraces, semi-Ds & bungalows.

Landed property renovations in Singapore span a wide range depending on typology and scope. A terrace interior renovation typically costs $120,000 to $300,000. A semi-detached sits between $250,000 and $500,000. A bungalow or Good Class Bungalow renovation usually starts at $500,000 and can exceed $1.5M when bespoke joinery, imported stone, landscape integration, and smart-home systems are involved.

A&A (Addition & Alteration) works add a second or third storey, rear extensions, or full reconfiguration, and typically cost $500,000 to $2M depending on typology and scale. A full rebuild — demolishing the existing house and building new — routinely exceeds $1.5M and triggers a different URA and BCA approval path.

At MET Interior, every quote is fully itemised and sits behind a CaseTrust-standard contract, so you know exactly what you are paying for before we sign. If your project involves structural works, extensions, or A&A, see our dedicated landed property renovation service — we are a BCA-licensed builder, so design and construction sit under one contract.

URA (Urban Redevelopment Authority) governs what you can build on landed property in Singapore. Purely internal renovations — that do not change the envelope, gross floor area, or structure — generally do not require URA written permission. Anything that alters the external envelope, adds floor area, or changes the building height triggers a full URA submission and usually a BCA structural submission, a qualified Professional Engineer, and a registered Architect.

Key constraints to know: maximum building height (typically 12m / 3 storeys + attic for 2-storey mixed landed zones), envelope control (setback from boundaries), site coverage caps, and for GCBs, a 1,400 sqm minimum plot size with strict low-density character controls.

MET Interior works with a panel of licensed Architects and Professional Engineers who handle the full URA + BCA submission, so the approval path is never your problem.

Addition & Alteration (A&A) works retain the existing structure — URA typically requires retention of at least 50% of the external walls and a substantial portion of the roof — while allowing significant reconfiguration inside and limited additions outside. A&A is faster to approve (typically 2–4 months), cheaper (you avoid full demolition and re-foundation costs), and preserves the land-use history of the plot.

A full rebuild demolishes the existing house entirely and treats the project as new construction. It gives maximum design freedom (you can re-plan setbacks, height, and layout from scratch) but costs significantly more (typically 40–70% premium over A&A), takes 12–18 months from approval to completion, and involves a longer URA approval path.

The right choice depends on the age and condition of the existing structure, your design ambitions, budget headroom, and tolerance for timeline. We walk every landed client through the trade-off before quoting — our landed renovation service covers the full A&A path, from feasibility study through URA/BCA approval to construction.
