On the outside, it reads as a discreet 2.5-storey landed home. Step inside, and you discover a four-level spatial puzzle — sunken, raised and interlocked volumes that extract every cubic metre of space allowed under planning guidelines. This is “maximum volume” living: a house that quietly hides a surprisingly generous interior.

Designing Four Levels Inside a 2.5-Storey Shell

Within the URA envelope control, the architect carved out:

• A sunken lower-ground level that opens to a courtyard or light well
• A main living floor aligned with street level for arrival and entertaining
• An upper family level with bedrooms wrapped around voids
• A loft / attic tier that still respects 2.5-storey height limits

Instead of stacking floors in a rigid way, half-levels, split stairs and double-volume voids create a sense of vertical flow and drama.

Light, Height and Air: The True Luxury

The key to making four levels feel airy — not cramped — lies in:

• Central voids that pull daylight into the heart of the home
• Full-height glazing facing internal courtyards, not just boundary walls
• Cross-ventilation paths planned from front to rear
• Visual connections between levels so family members remain “in touch”

Standing in the living room, you “borrow” height from the upper levels, making the space feel like a gallery rather than a typical terrace.

Multi-Generational Ready Without Feeling Overbuilt

With four usable tiers, the house can comfortably support multi-generational living:

• Lower-ground: guest suite, grandparents’ room or home office with private patio
• Main floor: living, dining and kitchen as the social hub
• Upper floor: children’s bedrooms and study areas
• Loft: master retreat, hobby space or quiet work-from-home studio

Each generation can enjoy privacy while still sharing common spaces that feel open and connected.

Smart Use of “Invisible” Spaces

The design makes use of areas that are often wasted in conventional landed homes:

• Under-stair niches turned into storage or reading corners
• Transition landings that double as workstations or display ledges
• Roof pitch utilised for attic storage or cosy loft corners
• Side setbacks converted into light courts and green pockets

The result: almost no dead space — every corner serves a function, a feeling or a view.

TopBroker Insight

In land-scarce Singapore, the future of landed living lies in volume, not just floor area. Homes like this four-level “2.5-storey” design show what’s possible when architects work closely with planning rules instead of against them. For owners, it means:

• More usable space without inflating the external bulk
• Better resale appeal due to clever planning
• Long-term flexibility as family needs change over time
