How to Choose the Right Contractor for Your Landed Rebuild

How to Choose the Right Contractor for Your Landed Rebuild in Singapore

Rebuilding a landed home is nothing like renovating a condo or upgrading an HDB resale flat. It involves structural engineering, BCA submissions, URA envelope control, foundations, M&E integration, and long-term project management.

The right contractor can deliver a beautiful, durable home.
The wrong one can burn months of time, cause hidden cost overruns, and even compromise structural safety.

This guide provides a realistic, Singapore-specific framework homeowners can use, whether you’re rebuilding an older terrace in Telok Kurau, a semi-D in Sunset Way, or a bungalow near Lentor, Springleaf, or Bukit Timah.

It also includes considerations unique to condo upgraders rebuilding their first landed home.

1. Choose a Contractor Experienced in Landed Rebuilds (Not Just Renovations)

This is the biggest mistake homeowners make, they assume all contractors are the same.

Renovation contractors usually specialise in:

• carpentry

• tiling

• partition walls

• false ceiling

• painting

• basic M&E

But a landed rebuild contractor must handle:

• demolition

• foundation reinforcement

• RC slabs, beams, columns

• structural submissions

• attic works

• basement construction

• drainage & sewer diversion

• roof waterproofing

• airflow & natural lighting strategies

If the contractor does not regularly do full rebuilds, they may underprice or oversimplify the project, which almost always leads to delays or variation orders later.

Areas where landed experience matters more

Districts with sloping terrain or older infrastructure:

• Binjai Park / Upper Bukit Timah

• Hillview landed pockets

• Pasir Panjang

• Kew Drive & Bedok South

• Springleaf (close to nature reserve slopes)

• Seletar Hills (older underground services)

2. Check Their Track Record in Similar Landed House Types

Different landed houses come with different challenges.

Terraces (Telok Kurau, Serangoon Gardens, Opera Estate)

Require contractors experienced with:

• party wall coordination

• natural lighting solutions

• narrow site logistics

• M&E concealment in tight spaces

Semi-Ds (Thomson Ridge, Sunset Way, Luxus Hill)

Require expertise in:

• balancing setback rules

• maximising GFA

• reinforcing existing boundary walls

Bungalows (Bukit Timah, Caldecott Hill, Sentosa Cove)

These projects need:

• more structural complexity

• larger M&E planning

• drainage engineering

• premium façade installations

When interviewing contractors, ask specifically:

“Can you show me completed rebuilds in a similar house type and neighbourhood?”

3. Verify Their Structural Engineer Partnerships

In Singapore, no rebuild happens without a PE (Professional Engineer – Structural).

A good contractor will work hand-in-hand with engineers experienced in:

• attic load calculations

• pool/basement load

• RC slab thickness

• retaining wall design

• soil condition response

• earthquake compliance (minor but required)

Warning signs:

• Contractor says “engineer not needed yet”

• Engineer is outsourced last-minute

• No clear structural proposal before pricing

This is especially important in:

• East Coast (soft soil in some pockets)

• Pasir Panjang (hilly terrain)

• Springleaf (soil variability due to nature reserve proximity)

4. Compare Detailed, Itemised Quotations (Not Summary Quotes)

A proper rebuild quotation in Singapore should be 40–80 pages long, covering:

• demolition

• earthworks

• RC structure

• roofing

• plumbing

• electrical

• windows

• waterproofing

• interior works

• external works

• supervision

• material specifications

Short quotations = guaranteed hidden costs.

What condos upgraders often forget

Condos hide all their M&E behind common property infrastructure.
In landed homes, everything is your responsibility, and everything must be priced clearly.

5. Understand Their Project Management & Site Supervision Capacity

A rebuild typically involves 20–30 subcontractors, including:

• piling team

• demolition crew

• steel bar benders

• formwork carpenters

• concrete team

• roof installers

• plumbers

• electricians

• window/glass specialists

• waterproofing crew

• tilers

• carpenters

• painters

• AC technicians

If the contractor lacks a strong site supervisor, workmanship will suffer.

Ask them:

• “How many full-time supervisors will be on site?”

• “How often will you update me on progress?”

• “Do you use WhatsApp site groups for transparency?”

6. Confirm That They Manage Authority Submissions (URA, BCA, SCDF, PUB)

Rebuilds require proper regulatory handling:

• URA → envelope control

• BCA → structural submissions, demolition

• PUB → drainage & sewer approval

• SCDF → fire safety

• NParks → tree retention, if applicable

Some contractors rely too heavily on architects; others take ownership themselves.
The best ones coordinate all parties seamlessly.

7. Ensure They Have Experience with Singapore’s Weather & Waterproofing Challenges

In landed rebuilds, waterproofing determines the long-term durability of the house.

High-risk areas:

• roof terraces

• balconies

• bathrooms on upper floors

• window-wall junctions

• basement walls

• pool retaining structures

Neighbourhoods like Siglap, Frankel, and Telok Kurau experience wind-driven rain due to coastal proximity, requiring stronger waterproofing systems.

Bukit Timah and Sunset Way may require extra attention due to mature tree root systems affecting drainage.

8. Evaluate Their Experience with Natural Ventilation & Lighting Design

A good landed home feels breezy and bright without relying heavily on aircon.

Contractors who have built in neighbourhoods like:

• Telok Kurau (deep plots)

• Serangoon Gardens (dense terraces)

• Thomson (mixed zoning layouts)
  know how to design:

• light wells

• skylights

• ventilation shafts

• open-riser staircases

• proper window placement

Homes built by inexperienced contractors often end up with dark, stagnant areas.

9. Check Their Timeline Management Record

Delays are common in:

• rainy months

• design changes

• authority rework

• complex demolitions

• narrow-site logistics

Ask for:

• Gantt chart timeline

• milestone-based planning

• average timeline for similar rebuilds

Homes near upcoming MRT hubs (Lentor, Marine Parade, Beauty World) sometimes require extra submission steps, so experience matters.

10. Assess Transparency in Variation Orders (VOs)

VOs are unavoidable, soil issues, structural surprises, material changes.

But the contractor should:

• update you immediately

• provide justification

• give cost breakdown

• offer alternatives

Unclear VOs = trouble.

11. Visit at Least 2–3 Active Sites

This is the MOST telling indicator.

Look for:

• site organisation

• safety practice

• material quality

• supervisor attentiveness

• workmanship precision

If a contractor has no active sites, it’s a warning sign.
