GCB, bungalow, semi-detached, and terrace renovation with in-house URA envelope control, BCA structural approval, and Professional Engineer endorsement. We don’t decorate landed homes. We re-engineer them.

Can Interea handle structural extensions and major A&A works?

Yes. As a design-build firm, we manage the entire architectural lifecycle. We specialize in Additions & Alterations (A&A), structural re-engineering, and spatial extensions, ensuring all works are fully compliant with BCA and URA guidelines.

How do you incorporate natural light and ventilation in landed homes?

We use Spatial Intelligence to identify opportunities for skylights, internal courtyards, and open-plan circulation. By understanding the path of the sun and prevailing breezes, we engineer environments that feel airy, bright, and naturally cooled.

What is the benefit of the Design-Build model for a Landed project?

Landed projects are technically complex. Our design-build approach eliminates the friction between architects and contractors. You have a single point of accountability for everything from the initial 72-Hour Design Sprint to the final structural handover, ensuring the project stays on schedule and within budget.

What Determines Your Renovation Investment

Landed property renovation has the widest investment range of any property type in Singapore — from interior-only works to full A&A structural projects. Interea assesses 6 key factors during the initial site visit to give you a precise, itemised budget with zero guesswork.

  • Project scope — interior-only, A&A works, or full reconstruction
  • Property type and size (GCB, detached, semi-D, terrace)
  • Structural modifications and BCA/URA submission requirements
  • MEP (mechanical, electrical, plumbing) engineering scope
  • Material and finish grade — residential to luxury
  • Timeline and phasing requirements

→ Start your 72-hour design sprint — get a full itemised budget within 3 business days.
