Landed House Renovation Cost in Singapore: 2026 Budget Guide
A landed house renovation in Singapore typically starts around S$90,000 for a basic terrace refresh and can pass S$1 million for a large bungalow with high-end finishes. The range is wide because landed homes bring larger floor areas, structural questions, approval fees and outdoor works that apartments rarely have. This guide is written for Singapore homeowners, and every figure is in Singapore dollars (S$).
We are Monarch Carpentry Design Studio, a design and carpentry studio based in Singapore, and we have set out below how the budget really breaks down, where it tends to surprise people, and how to keep it under control.
TL;DR
Published 2025 estimates for a terrace house of 1,500 to 2,500 sq ft run from S$90,000 (basic) to S$700,000 (high-end), and for a good-class bungalow from S$250,000 to S$3 million or more.
Structural changes need a Qualified Person and BCA approval, and those professional fees are often billed separately from the renovation contract.
Some works, such as extensions, may also need URA planning permission, so check before you design.
Extras like basements, landscaping and solar can add S$20,000 to S$300,000 each.
Ask every quote what is excluded: submission fees, carpentry, outdoor works and hacking are the usual gaps.

What landed house renovation costs in Singapore
The most useful published benchmark we can point to is the Renopedia 2025 cost guide, which splits landed homes into three tiers. The figures below come from that guide and are estimates, not quotes.
Property | Basic | Custom | High-end |
Terrace house (1,500 to 2,500 sq ft) | S$90,000 to S$180,000 | S$180,000 to S$350,000 | S$350,000 to S$700,000 |
Good-class bungalow (4,000+ sq ft) | S$250,000 to S$500,000 | S$500,000 to S$1.2 million | S$1.2 million to S$3 million+ |
The same guide lists add-ons that landed owners commonly consider: basement conversions at roughly S$120,000 to S$300,000 (requiring URA approval), eco-friendly upgrades such as solar panels or rainwater harvesting at S$20,000 to S$100,000, and landscaping with gardens or pools at S$50,000 to S$300,000.
Semi-detached houses sit between the two rows of the table. We would not stretch a terrace or bungalow figure over a semi-detached home without a site visit, because the condition of the structure matters more than the label.
What the three tiers usually mean
Basic: repainting, flooring replacement, bathroom and kitchen refresh, basic electrical and plumbing, and a modest carpentry package. The footprint and layout stay as they are.
Custom: reworked layouts, more bespoke carpentry, upgraded lighting, new wet areas, and often some wall removal.
High-end: premium stone and timber, extensive custom joinery, smart home systems, and frequently an addition and alteration (A&A) component.
None of these tiers is a promise of quality. A well-managed custom renovation can look far better than a poorly planned high-end one.
Why landed homes cost more than flats
Three factors push the number up.
Size. Floor area multiplies almost every line: flooring, painting, electrical points, ceiling work and carpentry. A 2,000 sq ft terrace house has several times the surface of a typical resale flat.
Structure and age. Many landed houses are decades old. Once ceilings and walls are opened, owners often find ageing wiring, old pipes, water seepage or timber damage. If you plan to use timber carpentry or built-ins, it is also worth understanding the termite risk in Singapore homes before you commit to a design.
Regulatory work. Landed properties come with URA and BCA processes that high-rise flats seldom involve. We cover these next because they are the most common source of budget shock.
Approvals and professional fees: the line items people miss
Not every renovation needs approval. The BCA keeps a page on building works not requiring approval, which exempts certain minor works. Anything beyond that needs a closer look.
BCA and the Qualified Person
According to CVC Engineers’ 2026 A&A guide, any renovation involving walls, columns, beams or slabs requires a Qualified Person, meaning a registered architect or professional engineer, to prepare plans and obtain BCA approval. The same guide gives typical fees of S$1,500 to S$5,000 for standard residential projects and S$10,000 to S$50,000 for major A&A or extensive structural changes. It also notes that BCA processing of standard structural plans usually takes 7 to 14 working days when documentation is accurate.
The BCA’s own page on structural plan submission explains that plan fees are computed from the Statistical Gross Floor Area, so a larger house means a larger fee.
URA planning permission
Depending on what you change in a terrace, semi-detached or detached house, you may need planning permission. URA’s page on land-titled residential renovation is the place to check whether your works qualify. For extensions, URA sets out the criteria for A&A to a landed house, which exclude, for example, properties in conservation areas and good-class bungalow areas. If your home is in one of those, the process is different and usually slower.
URA also offers the Landed Housing e-Advisor, an interactive tool that guides owners on alterations to a landed house. Use it before you brief a designer, so your wish list is realistic from day one.
The quote trap
CVC Engineers points out that a common pitfall is assuming a renovation quote includes submission fees. Professional fees for URA and BCA submissions on A&A works can run S$1,500 to S$10,000 or more and are often billed separately. Ask in writing who is responsible for them.
A worked example: building a landed budget
The numbers below are an illustration of how we would structure a budget conversation, not a quote and not a Monarch price. Take a 2,000 sq ft terrace house and a custom-tier envelope of S$250,000, which sits inside the published S$180,000 to S$350,000 range.
Contingency first. Set aside 10 to 15 percent, S$25,000 to S$37,500, for what the walls reveal. This is our working habit rather than a published rule.
Professional and approval fees. If walls or slabs change, confirm the Qualified Person’s fee separately, using the S$1,500 to S$10,000+ range as a sanity check.
Core works. Hacking, wet works, flooring, electrical, plumbing, ceilings and painting.
Carpentry. Wardrobes, kitchen cabinets, feature walls and built-ins, which often form a large share of any Singapore renovation. Our own carpentry budgeting guide goes into that share in detail.
Loose furniture and appliances. Often forgotten until the end.
Writing the budget in this order keeps the fixed and risky items visible before the discretionary ones.
What drives your landed house number up or down
Layout changes
Moving a kitchen, adding a bathroom or opening a living area to the garden costs more than refreshing finishes, because plumbing, drainage and structure change. If you are weighing a bigger social space, see our open concept living room guide.
Materials and finishes
Flooring alone can swing a budget by tens of thousands across three storeys. Our room-by-room flooring guide compares options for Singapore’s humidity.
Kitchens and wet areas
These are the most technical rooms. A kitchen renovation checklist helps you decide what to specify before quotes arrive, which prevents expensive variation orders later.
Outdoor and extras
Gardens, pools, car porch works and solar are where landed budgets often double. Decide early whether they belong in this phase or the next.
Design quality
Good space planning saves money by avoiding rework. Our Singapore space planning guide shows how layout decisions cut waste.
Ten ways to keep a landed renovation under control
Check URA and BCA requirements before design, not after.
Get quotes on the same scope sheet so they compare fairly.
Ask what is excluded, especially submission fees, outdoor works and disposal.
Phase the project: structure and wet areas first, finishes and landscaping later.
Keep a written contingency and agree how it is released.
Use bespoke carpentry where it earns its place, and standard items elsewhere.
Freeze the design before work starts, since changes mid-build are the costliest.
Inspect the roof, drainage and timber early.
Agree a payment schedule tied to milestones.
Work with a team that designs and builds together, so the drawings match what is feasible on site.
Our perspective
In our experience, the cost of a landed renovation is decided less by finishes than by how early the right questions get asked. Owners who come to us with a clear brief, a realistic envelope and a view on what must be approved tend to avoid the stressful mid-project reversals.
We built Monarch around an in-house team of designers and carpenters, because a design that has never met the workshop floor is usually a design that costs more to build. When the same people draw the joinery and make it, we can propose changes that keep the look while trimming cost, which is the core of our cost-effective approach. We would rather tell you early that a feature is expensive for little visual return than let it surface in a variation order.
We also encourage owners to treat carpentry as a design decision rather than a catalogue purchase. Well-planned built-ins can replace loose furniture, make rooms feel larger and last for decades, and that is where bespoke work pays back.

FAQ
How much does it cost to renovate a terrace house in Singapore?
Renopedia’s 2025 estimates for a terrace house of 1,500 to 2,500 sq ft are S$90,000 to S$180,000 for basic work, S$180,000 to S$350,000 for custom work and S$350,000 to S$700,000 for high-end work. Your own figure depends on the house’s condition, layout changes and carpentry scope. A site visit is the only way to get a reliable number.
Do I need approval to renovate a landed house?
Sometimes. Works touching walls, columns, beams or slabs need a Qualified Person and BCA approval, and some alterations or extensions also need URA planning permission. Minor works may be exempt, so check the BCA exemptions list and URA’s guidance, or ask your designer or Qualified Person.
Are submission fees included in a renovation quote?
Not necessarily. CVC Engineers notes that Qualified Person fees for URA and BCA submissions are often billed separately from the renovation contract. Ask for them to be listed as included or excluded in the quote.
How long does BCA approval take?
CVC Engineers reports that standard structural plans typically take 7 to 14 working days when documents are accurate. Complex A&A projects can take longer, so build time into your schedule before you move out.
Is renovating a landed house cheaper than a rebuild?
It depends on the structure. If the foundations and frame are sound, renovation or A&A is often the lower-cost route. If major structural defects appear, ask your Qualified Person to compare both options with figures.
