A Maisonette Is Not Just a Bigger Flat
Executive maisonettes are some of the most loved homes in Singapore — and some of the most underused. Older layouts, dark stairwells and two storeys of scattered storage can leave a rare double-storey HDB feeling smaller than it really is.
IS Design Studio designs maisonettes around vertical flow: how your family moves between levels, where light travels, and where storage should quietly live. Every project starts with a site assessment and works within HDB renovation guidelines — so the result is liveable luxury that is practical to approve and beautiful to come home to.
Staircase & Vertical Flow
The staircase is the heart of a maisonette. We treat it as a design feature and a connector — not an obstacle.
Family-First Space Planning
Living, dining, kitchen and bedrooms across two storeys, planned around your family’s real routines.
Storage That Disappears
Bespoke carpentry along stairs, landings and walls keeps a family home calm and clutter-free.

Condo Renovation Questions, Answered
Do you work within HDB renovation guidelines?
Yes. We design within HDB’s renovation rules and coordinate the required permits as part of every executive maisonette project.
Can the staircase be redesigned?
In many maisonettes, yes — cladding, balustrades, lighting and under-stair storage can transform it. Structural changes are assessed against HDB guidelines during the site assessment.
How do you plan storage for a two-storey home?
We map storage to where life actually happens — everyday items downstairs, personal storage upstairs, and bespoke carpentry that keeps both floors serene.
How long does a maisonette renovation take?
Most executive maisonette renovations take 10 to 16 weeks from confirmed design to handover, depending on scope. We map a realistic timeline at the proposal stage.
