Before Renovation Starts: Planning & Administration Checklist

There has to be paperwork and planning in place before a single wall is cracked. This is the phase where most homeowners get hung up.

HDB Renovation Permit & Approval

Some renovation work doesn’t require a permit, but structural changes do. HDB says you can only use registered contractors for any permitted works.


  • Apply for HDB renovation permit before works commence via HDB e-Service portal

  • Which walls are structural (wet walls, party walls) – these are not hackable

  • See if there are any estate upgrading restrictions on your block

  • As required by HDB, you must notify your neighbors in writing at least three days before the start of renovation work

How to budget for your renovation

Renovating a 5 room BTO in Singapore would generally range from S$50,000 to S$80,000 depending on the design scope and materials chosen. Premium finishes and full carpentry can drive up costs.


  • Break up your budget into categories: hacking, tiling, carpentry, electrical, painting, furnishing

  • Keep 10-15% as a contingency buffer for unforeseen costs

  • Compare at least three quotes from different interior design companies or contractors

  • Specify what is and what is not included in each quote — variation orders add up quickly

Design Planning Check List

Your design decisions affect everything downstream – materials, carpentry sizing, lighting placement, and even furniture choices. Get these early locked in.

Pick Your Interior Style

The popular styles for 5 room BTO in Singapore are Scandinavian, minimalist, contemporary and japandi. Each has a different palette of materials and spatial logic.


  • Determine your style before hiring a designer - Use reference images to communicate clearly

  • Consider how the style works with the natural light conditions of the orientation of your unit.

  • Discuss which rooms you want to prioritise – most families put their budget toward the living room, master bedroom and kitchen

Space Planning & Layout

A 5-room BTO has a floor area of about 110 sqm. A smart layout plan avoids furniture clutter and makes small rooms feel bigger.


  • Before confirming any measurements for carpentry, draw or have your designer create a scaled floor plan.

  • Early on, decide if the dining and living areas are to be merged or separate

  • Design traffic flow - doors, walkways and furniture placement should facilitate easy movement

  • Think versatile areas – a garden doubling up as a study nook, or a common bedroom converted to a home office

Materials and Finishes Inventory

The material you choose will directly affect aesthetics and long-term maintenance. Pick out items before the renovation starts, so that works are not delayed due to late deliveries.



Area

Common Material Options

Key Consideration

 

Living / Bedroom Floor

Vinyl planks, homogeneous tiles, timber

Durability, scratch resistance, ease of cleaning

Kitchen

Ceramic tiles, quartz countertop

Heat and stain resistance

Bathroom

Porcelain tiles, mosaic accents

Slip resistance, moisture tolerance

Carpentry (cabinets)

Laminate, veneer, lacquer

Cost, maintenance, finish consistency

Walls

Paint, wallpaper, feature wall panels

Humidity tolerance, ease of repainting



  • Large format tiles (600x600 and above) visually make smaller rooms appear larger Confirm tile sizing before ordering.

  • Choose grout colour carefully. Lighter grout will show stains, so darker grout is better for wet areas.

  • Use coordinated wood tones in flooring, woodwork and furniture for visual consistency

Carpentry Checklist

Carpentry is usually the biggest cost in a 5 room BTO renovation. Getting it right is a matter of balancing storage needs, aesthetics and cost.

Carpentry Essentials To Plan

  • Kitchen cabinets: Design upper and lower cabinet heights based on user heights. Base cabinet pull-out drawers for easy access.

  • Wardrobe: Swinging doors, sliding doors or open shelving. Plan the internal fittings (drawers, shelves, hanging rails) before the carpentry is built

  • TV Console & Feature Wall: Check the TV size and where it’s going to be mounted before designing the console – recess the cable trunking into the wall for a neat finish

  • Study or work desk : If you work from home a built-in desk with shelves above is a better use of a small room than freestanding furniture

  • Shoe cabinet: Often overlooked – plan for at least 20-25 pairs of footwear storage, plus a top shelf for bags

Quality Checks in Carpentry

  • Confirm brand and thickness of board (18mm standard, 25mm more durable)

  • Order a sample of the laminate finish before order confirmation – colours may vary between catalogue and actual material

  • Make sure soft-close hinges come as standard, rather than an add-on

Electrical, Lighting and Plumbing Checklist

These are the behind the walls decisions that are expensive to change later. Plan them before plastering or tiling the walls.


  • Identify all power point locations – include USB points at bedside tables and kitchen benches

  • Plan lighting zones: ambient, task and accent lighting in the living/dining area for flexibility with different moods

  • Select the positions of the ceiling lights before the false ceiling construction – moving a light point later means a variation order

  • For the kitchen, check if you will have a gas hob or induction. This will affect where the gas point and power sockets go.

  • Before you tile : make sure that the bathroom is waterproofed to Singapore building standards.

FAQ (Frequently Asked Questions)

How much does it cost to renovate a 5 room BTO in Singapore?

The cost to renovate a 5-room BTO flat usually ranges from S$50,000 to S$80,000, depending on the extent of design, material selection and carpentry work. Premium finishes at the high end can send the price soaring beyond this range. Basic renovations with less customisation will be cheaper at the low end.

Do I need to apply for a permit for 5 room BTO renovation works?

Yes, some works require a HDB renovation permit, such as hacking of walls, installation of window grilles and waterproofing of bathrooms. To ensure compliance, you are required to apply through the HDB e-Service portal and engage only HDB-registered contractors for approved works.

How long does it take to do up a 5 room BTO?

Most 5 room BTO flats take 8 to 12 weeks to renovate from start of work to handover. Timelines are determined by scope – extensive hacking, full carpentry and custom features will take longer than a simple package with standard finishes.

Most important carpentry items in a 5 room BTO?

The most important carpentry pieces are the kitchen cabinets, the bedroom wardrobes, the TV console and the shoe cabinet. These have direct implications on daily function and storage. Plan the internal fittings – the drawers, shelves and hanging rails – before you start building it, so that the carpentry will suit the way you live.

What is the best flooring for a 5 room BTO in Singapore?

Vinyl planks are a popular choice for Singapore BTOs due to their durability, water resistance and realistic wood look. Homogeneous tiles are easier to clean and are thus preferred in kitchens and bathrooms. Many homeowners opt for vinyl in bedrooms for the warmth underfoot and quieter acoustics.

When should I schedule my 5 room BTO renovation?

Start planning at least three to six months prior to your essential collection date. This gives you time to research interior designers, get quotes, set your design direction and lock in a renovation slot. Planning ahead also reduces the risk of delays caused by material lead times or contractor availability.
