BTO Wet and Dry Kitchen: Open or Closed? How to Plan It Before Key Collection

Many new BTO flats come with a compact wet kitchen next to an open dry kitchen area, and it has become a hot topic among homeowners this month. Some feel the wet kitchen is too small to cook in. Others like the flexibility to decide how much space goes to cooking and how much goes to living and dining.

This guide explains how the wet and dry kitchen are meant to work together, compares three ways to lay them out, and covers what to check with HDB's renovation guidelines before you commit. It is general information for homeowners, so always check your own floor plan and the current rules.

What HDB says about the wet and dry kitchen

In a Facebook post on 14 October 2026, HDB explained that the compact wet kitchen in the flats being discussed is designed to work together with the adjoining dry kitchen. HDB said these areas together occupy approximately 10 sqm, roughly the size of a standard kitchen in newer HDB flats that come with a service yard. HDB also said the open-concept kitchen has been the standard design for new BTO flats since 2018, whenever layout permits, and that floor plans with layout ideas are provided before flat selection so buyers can plan ahead (Mothership report).

In practice, that means the kitchen in many new BTO flats isn't a fixed room. How big it feels depends on how you plan the dry kitchen area, and that decision is best made before carpentry starts.

Wet kitchen vs dry kitchen: what goes where

• Wet kitchen: the sink, the hob and the hood, plus anything that splashes, steams or smokes. This is where heavy frying, washing up and soaking pots happen

• Dry kitchen: prep space, the fridge, small appliances such as the rice cooker, air fryer, water dispenser or coffee machine, and storage for dry food and crockery

• Shared needs: enough power points on both sides, good lighting over every work surface, and a clear path between the fridge, the prep counter and the sink

A common complaint about compact wet kitchens is that the sink and the hob sit close together and there's little space for appliances. Moving appliances and prep space into the dry kitchen usually solves most of this.

Option 1: Keep it fully open

An open layout treats the dry kitchen as part of the living and dining area. A peninsula or island counter often marks the edge.

• Good for: light cooks, small households, and anyone who wants the living and dining area to feel as large as possible

• Plan for: a strong hood, easy-to-clean surfaces, and closed storage so the open kitchen looks tidy from the sofa

• Trade-offs: cooking smells and noise travel into the rest of the flat, and the air-conditioning cools the kitchen area too

Option 2: Zone it without walls

A zoned layout keeps the space open but gives the kitchen its own identity, with a change in flooring, a counter that doubles as a dining ledge, a run of tall cabinets, or a ceiling detail and lighting that frames the kitchen area.

• Good for: households who cook a few times a week and want a sense of separation without losing space

• Plan for: where the dining table goes, so it sits in its own area and not in the walkway between the kitchen and the main door

• Trade-offs: it marks the zone visually but does little for smells or noise

Option 3: Add a glass or sliding partition

A sliding or fixed partition lets you close the kitchen when you're frying and open it up again after. Clear or fluted glass keeps daylight moving through the flat.

• Good for: frequent and heavy cooks, and families who want the open look most of the time but need a closed kitchen some of the time

• Plan for: stacking space for the panels when they're open, safety glass, and how the frame is fixed to the floor, wall and ceiling

• Trade-offs: it adds cost and a track to keep clean, and the position has to work with your fire escape route and natural ventilation

HDB's building works guidelines list the installation of a sliding glass door or PVC folding door at a kitchen entrance, without removal of the RC lintol or hanger, as work that does not need a permit. Erecting a single layer of 80mm glass block or 63mm hollow block is also listed as permit-free, subject to conditions such as adequate lighting and ventilation and a direct fire escape route. Removing or altering existing walls needs HDB's approval first. Our guide to glass-block, fluted-glass and sliding partitions covers the options in more detail, and our guide to what needs HDB approval explains the permit side. You can read the rules on HDB's building works page.

How to choose: questions for your household

• How often do you cook, and what kind of cooking? Daily stir-frying points towards a closable kitchen. Mostly reheating and light meals suits an open one

• How many people cook at once? If two people often cook together, plan more counter length in the dry kitchen

• Where does the laundry go? In some new layouts the laundry area sits close to the kitchen, so plan the washer, the drying rack and cooking space so they don't clash

• Which appliances do you own or plan to buy? List them before carpentry design, so each one has a place and a power point

• What will the flat look like from the main door and the sofa? That's what you'll see every day

Plan it before key collection

The best time to decide is before your designer finalises the layout, because the kitchen affects the carpentry, electrical points, plumbing and lighting. Bring your HDB floor plan and appliance list to your first meeting. Our BTO renovation timeline shows when each decision is needed, our HDB kitchen renovation guide covers materials and storage, and our key collection defect checklist helps you check the flat before work starts. For the first meeting, our renovation consultation checklist lists what to bring.
