Why landed renovation needs
a builder and a designer in one team.
Renovating a landed property in Singapore is construction, not just styling. Structural works, waterproofing, rewiring, URA and BCA submissions — the scope goes far beyond what a design-only studio can carry. MET Interior is a BCA-licensed builder and a CaseTrust-accredited design studio in one team, which means the people who design your home are accountable for building it.
We handle the full renovation spectrum for landed homes: interior renovations that keep the envelope untouched, Addition & Alteration (A&A) works that add storeys or extensions while retaining the existing structure, and rebuild management where starting over makes more sense. One contract, one project lead, weekly updates.
MET Interior is a BCA-licensed builder and CaseTrust-accredited design studio handling landed property renovation across Singapore — interior renovations, Addition & Alteration (A&A) works, and rebuild management for terrace houses, semi-detached homes, and bungalows. One team covers design, URA and BCA submissions through our panel of licensed Architects and Professional Engineers, construction, and handover. Interior renovations typically run $120,000–$500,000; A&A works $500,000–$2M.
The Specialist Lens
What landed renovation actually involves
Structural & envelope works
Roof, facade, waterproofing, and structural alterations — surveyed and priced before we quote, not discovered mid-build.
Aging services
Older landed homes usually need full rewiring and re-piping to current standards. We assess M&E condition upfront.
URA & BCA approvals
A&A and rebuild works need URA written permission and BCA submission. Our panel of Architects and PEs runs the process.
Living arrangements
Interior works can sometimes be phased around you; A&A usually means moving out. We plan the sequence with you honestly.

Interior renovation vs A&A vs reconstruction
| Interior renovation | A&A works | Reconstruction | |
|---|---|---|---|
| What changes | Layout, finishes, M&E — envelope untouched | Extensions, added storeys; ≥50% of external walls retained | Full demolition, new house |
| URA / BCA approval | Generally not required | URA written permission + BCA submission | Full new-construction approval path |
| Approval time | — | 2–4 months | Longer — treated as new construction |
| Typical cost | $120k – $500k | $500k – $2M | $1.5M – $5M+ |
| Typical duration | 4–7 months on-site | 9–14 months incl. approval | 12–18 months from approval |
| When it makes sense | Structure is sound, layout mostly works | Sound structure, need more space | Aging structure or a fundamentally different house |

Terrace house renovation in Singapore
Terrace houses are the most common landed renovation we handle. An interior renovation of an inter-terrace typically costs $120,000–$300,000 and runs 4–6 months on-site. Corner terraces add side-extension potential under A&A rules, which is often the most cost-effective way to gain floor area without a rebuild.
The usual scope: full rewiring and re-piping (most terraces are 30+ years old), waterproofing at the roof and rear service area, staircase reworking, and opening up the ground floor for a connected kitchen-living-dining flow. Conservation terraces in areas like Joo Chiat and Emerald Hill carry URA facade rules our panel Architects handle.
For a detailed cost breakdown, see our guide to terrace house renovation costs and rules, or read what it costs to renovate a landed property across all typologies.
The A&A approval process — URA and BCA
A&A (Addition & Alteration) works follow a defined approval path: a registered Architect prepares and submits plans for URA written permission, a Professional Engineer endorses the structural design for BCA submission, and construction can only start once both clear — typically 2–4 months. URA requires that at least 50% of the external walls and a substantial portion of the roof are retained for the project to qualify as A&A rather than reconstruction.
Height and envelope controls apply throughout: most 2-storey mixed landed zones cap buildings at 12m (3 storeys plus attic), with setback and site-coverage rules that shape what an extension can look like. Getting this right at feasibility stage — before design falls in love with something unbuildable — is exactly why we start every landed project with a site survey.
We cover the full submission mechanics in our A&A submission guide, and if you are still weighing the options, A&A vs reconstruction walks through how to decide.
Choosing a landed renovation contractor
Landed renovation sits in a regulatory gap that catches many homeowners: interior design firms without a builder licence cannot legally carry out structural works, while pure main contractors build well but leave design decisions to you. Check three things before signing with anyone: a BCA builder licence (searchable on the BCA directory), CaseTrust accreditation (your deposit is protected under a standard contract), and completed landed projects you can actually see.
MET Interior holds all three — BCA Licensed Builder, CaseTrust accreditation, and a landed portfolio built since 2011 — with design and construction under one contract. That matters most when something unexpected surfaces mid-build: there is no gap between the designer who drew it and the builder who has to solve it.
Budget-wise, our A&A cost guide breaks down where the money goes, and 17 common landed renovation questions covers the practical details owners ask us most. If your project is more about interiors than structure, start with our landed property interior design service instead.

Common questions
How much does landed property renovation cost in Singapore?
An interior renovation of a terrace house typically costs $120,000–$300,000; a semi-detached $250,000–$500,000; a bungalow $500,000–$1.5M+. A&A (Addition & Alteration) works run $500,000–$2M depending on typology and scale, and a full rebuild routinely exceeds $1.5M. Every MET Interior quote is itemised line-by-line.
Do I need URA approval to renovate a landed property?
Purely internal renovations that do not change the envelope, gross floor area, or structure generally need no URA permission. Anything that alters the external envelope, adds floor area, or changes building height requires URA written permission and BCA structural submission, with a registered Architect and Professional Engineer. We coordinate the full submission through our panel.
Should I do A&A works or a full rebuild?
A&A retains at least 50% of the external walls, is faster to approve (typically 2–4 months), and avoids full demolition and re-foundation costs. A rebuild gives maximum design freedom but costs 40–70% more and takes 12–18 months from approval to completion. The right call depends on the structural condition of the existing house and your budget headroom — we walk you through the trade-off before quoting.
How long does a landed renovation take?
Interior renovations run 4–7 months on-site for terraces and semi-detached homes, 8–12 months for bungalows. A&A works add 2–4 months of URA/BCA approval before construction starts. Design development is usually 6–10 weeks before either path.
Can an interior design firm handle structural renovation works?
Only if it holds a builder licence. MET Interior is a BCA-licensed builder as well as a CaseTrust-accredited design studio, so structural works, wet works, and A&A construction sit under the same contract as the design — one team, one point of accountability from drawings to handover.
Do you renovate corner terraces and inter-terrace houses?
Yes — inter-terrace, corner-terrace, and cluster houses are a large share of our landed work. Corner terraces often have side-extension potential under A&A rules, which we assess during the feasibility study. Conservation-zone terraces (e.g. Joo Chiat, Emerald Hill) need URA conservation submission, which our panel Architects handle.
Can we live in the house during renovation?
For interior-only works it is sometimes possible to phase the renovation floor by floor, though dust, noise, and utility interruptions make it uncomfortable. For A&A works involving the roof or envelope, moving out is effectively required. We plan the sequence and timeline with you before works begin.
Do you handle the URA and BCA submissions yourselves?
Submissions must come from a registered Architect and Professional Engineer, so we engage and coordinate our standing panel on your behalf. You get one point of contact; we run the approval process end-to-end.
What does the feasibility study cover?
Structural condition, M&E age and capacity, waterproofing state, plot constraints under URA rules (height, setback, site coverage), and an honest read on whether interior renovation, A&A, or rebuild fits your goals and budget.
Is a renovation deposit protected?
Yes — as a CaseTrust-accredited firm we operate under the CaseTrust standard contract, which protects deposits and locks the itemised scope before works begin.
What warranty do you provide?
A workmanship warranty covers our construction works, with defects rectification after the handover walkthrough and aftercare support beyond it. Waterproofing works carry their own extended warranty.
Do you also do the interior design?
Yes — MET Interior is a design studio first. Every renovation includes full design development with 3D renders. If your project is design-focused with no structural works, see our landed property interior design service.
