Landed renovation, inside and out

A landed house gives you more room to change things, and more to get right. Interior work on a sound house is close to a large condo job. Additions and alterations, such as extending a floor or adding a roof terrace, bring in architects, engineers and approvals. Our builder team mainly builds landed houses, so we plan the interior and any building work together.

What the work usually involves

  • Interior renovation: kitchen, bathrooms, flooring, built-in storage, lighting and air-conditioning.
  • Additions and alterations: extending a floor, an attic or a roof terrace, new staircases or reconfigured rooms.
  • Outside: gates, fencing, car porch, facade finishes and waterproofing of flat roofs and terraces.
  • Services: rewiring, new water pipes and drainage are common in older houses.
  • Strata landed homes in a cluster development add another layer: the MCST controls the facade and shared areas.

Rules and approvals

  • Building works that change the structure or add floor area usually need a qualified person, such as an architect or professional engineer, to submit plans to the authorities (URA for planning, BCA for building plans and structure).
  • Some minor works are exempt from approval, but whether yours is depends on the details. We check this before quoting, not after.
  • Strata landed homes need the MCST's approval for anything that changes the outside of the house, and follow its working hours.
  • Neighbours matter: protect shared walls and drains, and agree on access and noise before work starts.

Good to know

Questions owners ask

Do I need approval to renovate my landed house?

Interior work often does not, but structural changes and extra floor area usually need plans submitted by a qualified person to URA and BCA. We check what applies to your house before quoting.

Can I renovate a strata landed home freely?

Inside, mostly yes. Anything that changes the outside, such as the facade, gates or roof, needs the MCST's approval and must follow its rules.

How long does a landed renovation take?

About 3 to 4 months for interior-only work, and 6 to 12 months for additions and alterations that need approvals.

Can one team do the building work and the interior?

Yes. Our builder team mainly builds landed houses, so the structure and the interior are planned together.
