How to plan both floors, the staircase, light and the front of a double-storey terrace, semi-D or bungalow, with eight illustrative design concepts.
📍 We serve KL, Selangor & Putrajaya.
A good double-storey house design in Malaysia puts the daily rooms (living, dining, wet and dry kitchen, and often a guest or parents' room) on the ground floor, the bedrooms and a family hall upstairs, and uses the staircase, an open light court or a void to pull daylight and air through the middle of the house. This guide sets out design ideas for double-storey terraces, semi-Ds and bungalows, eight illustrative concepts, how to plan each floor, and the three routes to a two-floor home: renovating one, adding a storey, or rebuilding. If you already own a double-storey house and are comparing quotes, read how a second storey changes a renovation first.
Most double-storey houses in the Klang Valley were built by developers to a standard plan: a long, narrow terrace with a car porch at the front and the kitchen at the back, or a wider semi-D or bungalow with land on one or more sides. The plan you start with decides most of what a redesign can do, because the party walls, columns, beams and the position of the staircase are rarely worth moving.
Within that shell, four things decide whether a double-storey house feels good to live in. The first is how the two floors divide the day: where people cook, eat, rest and sleep. The second is the staircase, which every person in the house uses many times a day. The third is light and air, because a long terrace is dark and warm in the middle unless the design does something about it. The fourth is the front, which is the part neighbours see and the part most owners want to change first.
Design is also where the budget gets decided, long before any contractor quotes. A layout that keeps the kitchen and bathrooms where the pipes already run is far cheaper to build than one that moves them, and a brief that says which rooms matter most stops money being spread thinly across the whole house.
These concepts are illustrative design ideas, not photos of finished projects. Each one shows a direction that suits a particular house type and family, with the trade-off it brings.
Vertical aluminium slats across the upper bedroom windows give privacy from the houses opposite and cut the afternoon glare, while a deep canopy over the porch gives shade to the car and the front door. It suits an intermediate terrace whose front faces the street directly. Ask how the slats will be cleaned and how they meet the window frames, because that is where rain gets in.
Opening part of the upper floor over the living room creates a tall space with high windows and a balcony corridor above. It looks generous and brings light deep into the ground floor, but it costs bedroom floor area and lets sound and cool air travel upstairs. It suits a family that values one dramatic room over an extra bedroom.
The space at the top of the stairs becomes a second living room with a sofa, shelves and a study desk, so children can do homework near their bedrooms and the downstairs stays tidy for guests. It works best with a window or balcony door, because an internal hall with no daylight feels like a corridor.
A bedroom with its own small bathroom on the ground floor means elderly parents, guests or a helper never need the stairs. In a terrace it usually replaces a store room or part of the dining area; in a semi-D it can sit on the side land. Wide doors and a level floor into the bathroom matter more here than the finishes.
A straight staircase along the party wall, with cabinets, a shoe bench or a small study filling the space beneath, turns dead space into storage. Timber-look treads and a slim railing modernise an old concrete stair without rebuilding it.
A dry kitchen with an island opens to the dining area, while a wet kitchen behind a glass partition takes the heavy cooking. A narrow skylight or high window above the wet kitchen helps with daylight and smoke, which matters in a terrace where the rear may be enclosed by an extension.
An open court or air well in the middle of a long house lets light and air reach the rooms on both floors, and upstairs bedrooms can open louvred windows onto it. It needs a proper drain at the bottom and a plan for heavy rain; many owners cover theirs with a raised roof that still lets air through.
Wide roof overhangs shade the upper walls and windows, keep rain off the frames and make a covered balcony possible. On a bungalow with land around it, this is one of the simplest ways to keep the upper floor cooler without relying on air-conditioning alone.
The ground floor carries the busiest part of family life, so plan it around how the household actually cooks and eats. Many Malaysian families want a wet kitchen for heavy frying and a dry kitchen or pantry that can open to the dining area; the split works best when the wet kitchen sits at the back, near the drains and the yard. A walk-through from the porch to the kitchen that does not cross the living room keeps groceries and shoes out of the main space.
Decide early whether the ground floor needs a bedroom. A room for parents, a helper or a future need is far easier to plan in at the design stage than to squeeze in later, and it often needs a small bathroom of its own. Keep in mind which walls hold the house up: non-structural brick walls between the living and dining areas can usually be opened, but columns and beams stay, and a design should work around them. Ideas for the back of a terrace, including the wet and dry split, are collected in terrace house kitchen design ideas.
Upstairs is usually the bedrooms around a landing at the top of the stairs. The master bedroom often sits at the front over the porch, with access to a small balcony, and the smaller rooms run along the length of the house. The landing is the space most worth designing: with a window, a sofa and some shelves it becomes a family room; ideas for it are in upstairs family hall design.
Bathrooms upstairs sit over the rooms below, so their position is a design decision with long-term consequences. Stacking them over the kitchen or another bathroom keeps pipe runs short and means a future leak stains a utility ceiling rather than the living room; the way these leaks are traced is explained in upstairs bathroom leaks. If you are tempted by a double-volume living room, weigh the extra light against the bedroom floor area it uses up; closing or opening a void sets out both directions.
| Room | Usual position | Design question to settle |
|---|---|---|
| Master bedroom | Upstairs front, over the porch | Balcony or larger wardrobe? Sun from the front? |
| Other bedrooms | Upstairs, along the length of the house | Windows to the outside or to a light court? |
| Family hall | Landing at the top of the stairs | Lounge, study corner, or both? |
| Guest or parents' room | Ground floor, rear or side | Own bathroom? Level access without steps? |
| Wet kitchen | Ground floor, at the back | Ventilation and drains; glass partition to the dry kitchen? |
| Bathrooms upstairs | Stacked over wet areas below | What sits underneath if a floor ever leaks? |
In most terraces the staircase runs along one party wall in the middle of the house. Moving it frees space in some layouts, but it means cutting and recasting slabs, so it is structural work with its own design and approval; moving or adding a staircase covers what that involves. For most owners the better design move is to keep the stair where it is and change how it looks and works.
Three changes make a big difference without touching the structure: new treads over the old terrazzo or mosaic, a lighter railing, and proper lighting on the landing. The space under the stair can become storage, a powder room or a small study; under-stair storage ideas shows the options. If anyone in the house has trouble with steps, plan handrails on both sides now; handrails and stair lifts explains what fits a typical domestic stair.
A double-storey house heats up from the top. The roof sits over the bedrooms, so the upper floor takes the afternoon heat while the ground floor stays cooler under a concrete slab. Good design deals with this at the roof first, with insulation and ventilation in the roof space; roof insulation options are compared on their own page. Deep eaves, slats or louvres over west-facing windows and light-coloured roof and wall finishes all reduce how much heat reaches the rooms.
Long terraces are dark in the middle. Air wells, light courts, high windows on the staircase and glass partitions help daylight reach the centre of the plan, and they let warm air rise and escape. Many owners cover an air well to stop rain and pests, which keeps the light but can trap heat if no gap is left for the air; courtyard and air well design shows ways to keep both.
The facade is where a double-storey house shows its style, and on a terrace it is also where privacy and glare are won or lost. Common moves include a slatted or louvred screen across the upper windows, a deeper porch canopy, a feature wall in stone or brick-look cladding, and a new paint scheme that makes an older house look current. The full set of looks, from minimalist to tropical, is in house exterior design ideas.
On many double-storey terraces the flat roof of the car porch doubles as the master bedroom's balcony. Turning it into a usable outdoor room needs care with waterproofing, falls to the drain and railings; terrace house balcony design covers the ideas and the pitfalls. Keep in mind that in many estates the front of a landed house is controlled by the council or the residents' guidelines, so check before changing the outline of the facade.
The same design ideas play out differently depending on how much land and how many outside walls the house has. Use this as a starting point for your brief:
| House type | Design strengths | Design limits | Ideas that usually fit |
|---|---|---|---|
| Intermediate double-storey terrace | Efficient plan, porch at the front, yard at the back | Only two outside walls; dark and warm in the middle | Light court or skylight, slatted front, under-stair storage |
| Corner or end terrace | An extra side wall for windows, side land | Side land use is controlled; more exposure to sun | Side windows on the stair, ground-floor guest room on the side |
| Double-storey semi-D | Wider plan, three outside walls, side garden | Shared wall on one side | Double-volume living, family hall with a balcony, wet and dry kitchen with a side yard |
| Double-storey bungalow | Land and windows on every side | More roof and wall to heat up and maintain | Deep eaves, covered balconies, ground-floor parents' suite |
Interior ideas for wider landed houses are gathered in semi-D and bungalow interior design; if your house is on one floor today, start with single-storey terrace design ideas before you decide to build upwards.
A double-storey design can be reached in three very different ways, and the route matters more than any style decision because it sets the scale of the work, the approvals and how long the family is affected.
| Route | When it fits | What it involves | Read next |
|---|---|---|---|
| Redesign an existing double-storey house | The structure is sound and the layout mostly works | Layout changes inside the shell, kitchens, bathrooms, stairs, facade and finishes | This guide |
| Add a storey to a single-storey house | The land is fully used and the family needs space | An engineer's check of the structure, new floor and roof, plans approved before work starts | Adding a second storey |
| Demolish and rebuild | The structure is failing or the house you need cannot fit the old shell | New design, foundations and structure, with full plan approval | Demolish and rebuild vs renovate |
Adding a storey and rebuilding are new building work, not renovation. They start with a structural assessment and plans, and they change the house's approved drawings, which matters later when you sell or refinance.
Not every design change needs approval, but many on a double-storey house do. As general guidance, work that changes the structure, adds floor area, encloses open space or changes the outline of the house normally needs drawings prepared by a registered architect or draughtsman, structural input from a professional engineer, and the local council's approval before anything is built. Cosmetic work inside the house, such as new finishes, cabinets and lighting, usually does not.
The rules differ between councils, and who may sign which drawings depends on the size and type of work, so confirm the requirements with the professional you appoint and with your council. Who can submit building plans explains the roles of the architect, the draughtsman and the engineer. For building work, check that the contractor is registered with CIDB before you sign.
A clear brief saves weeks of redrawing. Before the first meeting, write down the answers to these:
A good designer will come back with questions about the structure, the existing pipes and wiring and any approved plans you hold. Bring the developer's floor plans if you have them, and keep a list of every change you agree, so the drawings and the final quote describe the same house.
