Singapore HDB Kitchen Carpenter: 4-Room Space Planning

A Singapore HDB kitchen carpenter plans a 4-room flat kitchen around a number most owners never hear: about 2.4 to 3 metres of counter length and a floor near 90 square metres for the whole flat. That counter is enough for a real kitchen if the carpenter respects the work triangle and resists filling every wall with doors. The 4-room is the most common BTO in Singapore, so its kitchen is the one worth getting right.

The work triangle that fits

The sink, the cooktop, and the fridge form the triangle. In a 4-room, keep the sink and cooktop on the same run with the fridge at the end or on the return wall, so you move in a short L rather than across the room. Stretch that triangle too far and you walk metres for every meal. A carpenter who spaces the three points for a small flat, not a showroom, saves your legs.

Put the dishwasher beside the sink, not across the room, because the dirty plates travel one step. The bin pull-out goes in the same base as the sink, so scraping and rinsing happen in one spot. These are the placements that make a 4-room kitchen feel bigger than it is.

Where the storage should sit

Use the wall run for top cabinets and the base for drawers, not doors. A 4-room kitchen has room for a tall unit beside the fridge for the oven and the brooms, which frees the base for cooking gear. Full-height cabinets to the 2.6 metre ceiling grab the dead space above the top row for festive ware.

The service yard sits next to the kitchen in most 4-room flats, so the carpenter can extend storage into that edge: a slim cabinet for the washing machine, a rack on the yard door, a overhead shelf for the laundry. The boundary between kitchen and yard is where small flats quietly gain a metre of usefulness.

Leave the floor clear

A 4-room kitchen fails when the floor fills with a trolley, a bin, and a step stool. Plan those into the carcass: bin pull-out in the sink base, step stool in a narrow filler, trolley only if the walkway allows. The carpenter who designs the floor to stay empty gives you a kitchen that breathes.

The service yard as kitchen overflow

Most 4-room flats put the service yard beside the kitchen, and that edge is free space most owners waste. A slim cabinet for the washing machine, a rack on the yard door, and an overhead shelf for the laundry keep the wet work out of the cooking zone. The carpenter who extends storage into that boundary gives you a metre of usefulness without touching the kitchen footprint. Treat the yard as the kitchen's utility wing, and the counters stay clear for food instead of detergent and pegs. Plan the two rooms as one workspace in the first drawing, because the door between them is where the daily traffic actually flows.

A 4-room kitchen also benefits from a defined prep spot away from the heat. A small section of open counter near the fridge, kept clear by the drawer plan, is where you land groceries and chop, and the carpenter who protects that strip from being filled with cabinets respects how you move more than how the room photographs.

A 4-room kitchen is enough when the triangle is tight, the storage is vertical, and the floor is clear. Plan it like a daily workspace, not a display, and the size stops mattering.
