How Long Does It Take to Renovate or Rebuild a Landed House in Singapore?

One of the most common questions homeowners ask at the start of a project is:

“How long will everything take?”

While each project is different, understanding the typical stages of a residential project can help set realistic expectations.

1. Feasibility and Concept Design

Estimated duration: 1–2 months

This early stage studies the site, planning constraints, and potential design approaches.

It allows homeowners to understand:

• What is possible on the site
  
  

• Whether A&A or rebuilding makes more sense
  
  

• Approximate construction scale
  
  

2. Design Development

Estimated duration: 2–3 months

During this stage the design is refined and coordinated with structural and engineering requirements.

Key decisions include:

• Internal layouts
  
  

• Building form
  
  

• Materials and façade design
  
  

3. Authority Submissions

Estimated duration: 3–4 months

Residential projects typically require approvals from authorities such as:

• Urban Redevelopment Authority
  
  

• Building and Construction Authority
  
  

• Singapore Civil Defence Force
  
  

Approval timelines depend on the complexity of the proposal.

4. Tender and Contractor Appointment

Estimated duration: 2-3 months

During this stage the design is priced by contractors and the construction team is finalised.

5. Construction

Typical durations:

A&A projects : 9–12 months
Rebuild projects : 15–24 months

Actual timelines vary depending on project complexity and site conditions.

Final Thoughts

Residential projects require coordination between design, authorities, and construction. Planning the timeline early allows homeowners to manage expectations and make better decisions during the design process.
