Renovating your HDB flat is one of the most exciting yet challenging undertakings you can take on as a homeowner. It is a chance to design a home that reflects your personality and fits your lifestyle needs, but it can also be overwhelming with the many decisions, costs, and regulations involved. Local renovations are subject to HDB renovation guidelines, and understanding what you can and cannot do is critical for avoiding unnecessary hassles.
Discover the renovation dos and don’ts room by room, providing practical tips for creating a stylish, functional, and compliant HDB home. Whether you are working with an interior designer or managing it DIY-style, these considerations will help you achieve a space that balances design aspirations with regulatory requirements.
General Dos and Don’ts for HDB Renovations
Considering the general framework of HDB renovations is necessary before diving into specific rooms. HDB flats come with structural limitations that must be respected, and renovations must comply with the HDB renovation guidelines set out by the Housing & Development Board.
Do: Work with HDB-Registered Contractors
Hiring a contractor who is registered with the HDB is a must. Registered contractors are aware of the rules and know how to follow them, including obtaining permissions before starting any work. This approach reduces the possibility of delays or fines and guarantees that all work is completed to the required standard.
Do: Plan Your Timeline Around the Three-Month Window
HDB renovations are only allowed for a maximum period of three months from the date of key collection. Careful planning is essential to ensure that all work can be completed within this timeframe, especially if your renovation scope is significant.
Don’t: Remove Structural Walls
Trying to remove structural walls without permission is one of the most common blunders made by homeowners. These walls are integral to the building’s integrity, and removing them can compromise safety. Always check with your contractor and seek HDB approval before considering any form of wall hacking.
Don’t: Ignore Noise Restrictions
HDB flats are shared spaces, and respecting your neighbours is critical. Noisy works, such as drilling and demolition, can only be carried out between 9 am and 5 pm on weekdays. Avoid scheduling noisy jobs on weekends and public holidays, as these are prohibited.

Living Room Dos and Don’ts
The living room is typically the first area your guests see and the space where you spend the most time. Creating a warm yet functional environment is essential, but it is important to work within the HDB renovation guidelines.
Do: Use Light to Enhance Space
HDB living rooms aren’t necessarily spacious, but they might appear larger with some clever lighting. Opt for a combination of ambient lighting, such as ceiling lights, and accent lighting, like floor or table lamps, to create a layered and welcoming atmosphere. Mirrors strategically placed opposite windows can also enhance natural light.
Do: Choose Neutral Colour Palettes
Neutral tones work well in living rooms as they provide a calming backdrop and complement a variety of design styles. Greys, beiges, and muted blues are particularly popular choices for HDB flats. You can inject personality with accent colours through cushions, rugs, and art.
Don’t: Over-Clutter with Built-Ins
Although built-in storage is a functional way to maximise available space, overdoing it can make the area feel cramped. Strike a balance by combining built-ins with standalone furniture pieces. Avoid floor-to-ceiling cabinetry along every wall, as it can limit flexibility and overwhelm the space.
Don’t: Ignore Electrical Planning
Renovations offer the perfect opportunity to upgrade your electrical layout. Plan power points for your entertainment systems, charging stations, and lighting fixtures carefully. Avoid using too many extension cords since they can pose risks and cause clutter.

Kitchen Dos and Don’ts
The kitchen is the heart of the home, and a well-designed layout can make daily routines far more efficient. However, HDB kitchens have specific limitations under the HDB renovation guidelines, particularly regarding wet works and plumbing.
Do: Plan a Functional Workflow
Consider the kitchen triangle: the relationship between the stove, sink, and refrigerator. These three elements should be positioned in a way that minimises unnecessary movement when cooking. An L-shaped or straight-line plan is frequently the most effective for small HDB kitchens.
Do: Invest in Quality Ventilation
Cooking smells can stick around in small flats, so good ventilation is a must. Installing a quality hood and fan system will help keep grease and odours from spreading to the rest of your home.
Don’t: Relocate Sinks or Stoves Without Approval
Relocating sinks, stoves, or other wet areas might seem like a good idea, but it usually involves major plumbing changes that are tightly regulated. Always get the HDB’s approval before shifting these fixtures to avoid costly mistakes.
Don’t: Skimp on Durable Materials
Your kitchen gets a lot of use, so cheap materials won’t last. Choose durable finishes, like quartz countertops, moisture-resistant laminated cabinets, and backsplash tiles that are easy-to-clean. Avoid materials that stain easily or can warp when exposed to heat and moisture.

Bathroom Dos and Don’ts
Bathrooms are often the most challenging areas to renovate due to their size and the need to waterproof them correctly. Strict HDB renovation guidelines apply to bathroom renovations, so attention to detail is critical.
Do: Waterproof Properly
HDB requires all bathroom floors to be waterproofed by their appointed contractors, and there’s a mandatory seven-day curing period for the waterproofing membrane to fully set. It might feel like a delay, but this step is essential to prevent leaks that could cause serious damage to your neighbours’ units.
Do: Maximise Vertical Storage
Most HDB bathrooms are compact, so it makes sense to go vertical. Wall-mounted cabinets and floating shelves are a great way to keep your essentials organised without cluttering up the limited floor space.
Don’t: Replace Floor Slabs on Your Own
The bathroom floor slab is a key structural element, and tampering with it can compromise the building’s safety. Even works like retiling must be done by an HDB-appointed contractor to ensure everything stays compliant and secure.
Don’t: Overcrowd with Fixtures
It’s tempting to add double sinks or a large bathtub, but too many oversized fixtures can easily overwhelm a small bathroom. Stick to compact, multi-functional fittings that match the proportions of the space.
Bedroom Dos and Don’ts
Bedrooms are your personal retreat, so, apart from HDB renovation guidelines, comfort and practicality should also guide your decisions.
Do: Prioritise Ventilation and Light
Fresh air and natural light are important for a healthy home. Place your bed near windows but not directly in the sun. Lastly, use sheer curtains to let in light while keeping your privacy.
Do: Opt for Multi-Functional Furniture
Multi-purpose furniture, like storage beds or foldable desks, can make the room more versatile.
Don’t: Install Heavy Built-Ins Around the Bed
While built-ins can create a sleek, seamless look, avoid installing bulky overhead cabinets above your bed, as they can make the room feel claustrophobic and pose a safety hazard.
Don’t: Block Airflow with Poor Layout Choices
Avoid putting large wardrobes or furniture in the way of windows or airflow. This approach can make your room feel stuffy and smaller than it really is.

Balcony and Service Yard Dos and Don’ts
These areas are often overlooked but can greatly enhance your HDB flat’s liveability when designed thoughtfully.
Do: Use Outdoor-Appropriate Materials
Choose weather-resistant flooring and furnishings if you plan to use your balcony as a sitting area. Meanwhile, in service yards, durable shelving and hooks can aid in organising laundry tools.
Do: Integrate Greenery
Compact potted plants or vertical gardens can enliven balconies and service areas. Simply make sure they don’t obstruct drainage systems or serve as breeding sites for pests.
Don’t: Extend Floor Area Illegally
Extending the balcony area into the internal living space is strictly prohibited by the HDB renovation guidelines. Any alterations to the building’s external façade or structural elements require prior approval.
Don’t: Overload the Space
These spaces frequently fulfil functional roles, like hanging laundry to dry, so refrain from overcrowding them with excessive furniture or decor.

Dining Area Dos and Don’ts
The dining area often overlaps with the living room or kitchen in an HDB flat. Designing this zone well and in alignment with HDB renovation guidelines can make everyday meals and gatherings more enjoyable.
Do: Choose the Right-Sized Dining Set
Measure your space precisely before purchasing dining furniture to ensure an exact fit. A dining table with extendable features represents an excellent solution for compact apartments since it enables flexible hosting of guests.
Do: Create Visual Separation
Employ rugs, partitions, or different flooring materials to visually define your dining area, especially if it shares space with other zones.
Don’t: Skimp on Lighting
A chandelier or pendant light placed centrally above the dining table can visually anchor the space and provide a warm dining environment. Prevent harsh fluorescent lighting which can make eating feel hectic.
Don’t: Block Walkways
The dining table needs enough open space for visitors to navigate around it without collisions.
Final Tips for a Smooth HDB Renovation
Renovating your HDB flat requires balancing design aspirations with the HDB renovation guidelines. To avoid unnecessary stress, start with a clear plan and budget. Engage experienced professionals, and do not hesitate to ask questions about permits, timelines, and compliance.
Do: Stay Organised
All permits , together with contracts and invoices, should be stored in one location for quick access. Update your renovation schedule frequently while monitoring expenses to stay within your budget limits.
Don’t: Rush the Process
Good design takes time. Avoid making hasty decisions on finishes or layouts just to meet deadlines, as this can lead to regrets later.
