HDB Renovation Cost in Singapore 2026: What Your Renovation Budget Really Gets You

Renovating an HDB flat in Singapore is a major investment. Whether you are collecting the keys to a new BTO or renovating an older resale flat, one of the first questions most homeowners ask is:

“How much should I budget for my renovation?”

The answer is not as simple as choosing a renovation package from a price list.

The final cost of an HDB renovation depends on the size of the home, existing condition, amount of hacking required, carpentry, electrical and plumbing works, materials, design complexity and, most importantly, what you actually want to achieve.

In 2026, homeowners are also becoming more careful about where their renovation money goes. Instead of simply looking for the cheapest quotation, many are asking a more important question:

“What am I actually getting for the money I spend?”

At Blackwoods Interior, we believe this is the right way to look at renovation costs.

There Is No One-Price-Fits-All HDB Renovation

Two homeowners can renovate two flats of similar sizes and end up with very different renovation costs.

For example, a homeowner who wants a simple minimalist renovation may spend considerably less than someone who wants extensive built-in carpentry, feature walls, concealed doors, premium finishes and extensive electrical works.

Your renovation budget is influenced by several factors:

• Property type and size

• New BTO or resale HDB

• Existing condition of the property

• Amount of hacking

• Flooring requirements

• Carpentry

• Kitchen renovation

• Bathroom renovation

• Electrical works

• Plumbing works

• Painting

• Lighting

• Air-conditioning

• Material specifications

• Design complexity

This is why comparing two renovation quotations based only on the final number can sometimes be misleading.

Where Does Your Renovation Budget Actually Go?

Instead of looking at renovation as one large number, it is better to divide the budget into different components.

1. Carpentry

For many HDB homes, carpentry can represent one of the largest portions of the renovation budget.

Common carpentry works include:

• Kitchen cabinets

• Wardrobes

• TV consoles

• Shoe cabinets

• Feature storage

• Vanity cabinets

• Utility storage

• Full-height cabinets

The cost depends on the amount of carpentry, dimensions, internal configuration, board specification, laminates, hardware and design.

A kitchen with basic cabinet storage will naturally cost less than a highly customised kitchen with multiple drawers, specialised storage systems and premium hardware.

This is why homeowners should not simply ask:

“How much is carpentry per foot?”

It is more important to understand what is included within that price.

2. Electrical Works

Electrical works are often underestimated when homeowners first plan their renovation.

A modern home may require considerably more electrical points than an older home.

You may need points for:

• Television

• Wi-Fi equipment

• Computers

• Washing machine

• Dryer

• Refrigerator

• Oven

• Induction cooker

• Dishwasher

• Water heater

• Air-conditioning

• Feature lighting

• Pendant lights

• Bedside charging

The location of these points also matters.

A beautifully designed home can become inconvenient if you constantly need extension plugs because the electrical layout was not planned properly.

3. Plumbing and Bathroom Works

Bathrooms can look simple, but there are many components involved in a proper renovation.

Depending on the project, works may include:

• Hacking

• Waterproofing

• Tiling

• Sanitary fittings

• Shower fittings

• Basin

• Vanity

• WC

• Floor trap

• Plumbing

• Water heater connections

For resale flats, existing conditions can also affect the amount of work required.

This is one reason why homeowners should not assume that every bathroom renovation will cost the same.

4. Flooring and Wall Finishes

Flooring can dramatically change the appearance of a home.

Depending on the design, homeowners may choose:

• Tiles

• Vinyl

• Timber flooring

• Engineered wood

• Porcelain tiles

• Large-format tiles

The cost depends not only on the material itself but also on preparation, installation and the condition of the existing floor.

Wall finishes can also vary significantly.

Paint is generally straightforward, while feature walls, textured finishes, wallpaper, microcement-style finishes or customised wall treatments can add to the overall cost.

5. Hacking and Demolition

Hacking is another area where renovation costs can change significantly.

A new BTO may require relatively limited demolition compared with an older resale flat.

A resale property may have:

• Existing built-in cabinets

• Old flooring

• Existing kitchen cabinets

• Feature walls

• False ceilings

• Existing bathroom finishes

• Previous renovation works

Removing these elements takes time, manpower and disposal arrangements.

Therefore, when comparing renovation quotations, check whether demolition and disposal are included.

How Much Should You Allocate for Carpentry?

There is no universal amount because every home has different requirements.

Instead of starting with a fixed carpentry budget, start by identifying what you actually need.

For example:

Essential carpentry

• Kitchen cabinets

• Wardrobe

• Shoe cabinet

Useful carpentry

• TV console

• Study storage

• Additional bedroom storage

Lifestyle carpentry

• Feature walls

• Display cabinets

• Specialised storage

• Custom furniture

This approach allows homeowners to prioritise their spending.

You may discover that you would rather spend more on a good kitchen and less on decorative carpentry.

Why Cheap Renovation Quotations Can Become Expensive

A low renovation quotation is not necessarily a bad quotation.

However, homeowners should understand why one quotation is significantly cheaper than another.

Look carefully at:

• Quantity of carpentry

• Board specifications

• Hardware brands

• Countertop material

• Electrical point quantity

• Lighting

• Plumbing

• Hacking

• Disposal

• Painting

• Waterproofing

• Installation

• Project management

• Exclusions

For example, one contractor may quote a lower price because certain items are excluded.

Another company may have included those items from the beginning.

When comparing quotations, compare scope, not just price.

Should You Spend More on Materials?

Not necessarily.

The most expensive material is not always the best choice for every part of your home.

Instead, consider where durability matters most.

For example, areas that experience heavy daily use may deserve greater attention.

Your kitchen countertop, cabinet hardware, kitchen fittings and flooring may experience considerably more wear than a decorative feature wall.

A good renovation budget prioritises money according to how the home will actually be used.

How to Control Your HDB Renovation Budget

If your budget is limited, you do not necessarily need to compromise on the overall design.

Instead, consider these approaches.

Prioritise the Important Spaces

Spend more on areas you use every day.

For many homeowners, this could mean:

• Kitchen

• Master bedroom

• Living room

• Bathrooms

Reduce Unnecessary Carpentry

Not every wall needs a built-in cabinet.

Too much carpentry can also make an HDB flat feel smaller.

Choose Timeless Finishes

You do not need expensive materials everywhere to create a premium-looking home.

Good proportions, lighting, colour coordination and material combinations can make a significant difference.

Plan Before Work Starts

Changes made during renovation can become expensive.

Changing the layout after electrical, plumbing or carpentry works have started may involve additional labour and materials.

The earlier decisions are finalised, the easier it is to control the renovation budget.

Renovation Budget vs Renovation Value

One of the biggest misconceptions about renovation is that spending more automatically creates a better home.

It doesn't.

A $150,000 renovation does not necessarily provide twice the value of a $75,000 renovation.

The quality of a renovation depends on how effectively the budget is allocated.

A well-planned renovation can look sophisticated without excessive spending.

The key is understanding where your money should go.

Questions to Ask Before Signing Your Renovation Contract

Before committing to a renovation company, ask:

1. What exactly is included in the quotation?

2. What items are excluded?

3. Are hacking and disposal included?

4. What board specifications are being used?

5. What hardware is included?

6. How many electrical points are included?

7. Are plumbing works included?

8. What happens if additional works are required?

9. What is the estimated renovation timeline?

10. How are defects handled after handover?

A detailed conversation before renovation begins can prevent many misunderstandings later.

The Best Renovation Budget Is One You Can Understand

There is no magic renovation budget that applies to every HDB homeowner.

Instead, your budget should be based on:

Your home + your lifestyle + your priorities + your desired design.

A good renovation company should be able to explain where your money is going rather than simply giving you one large figure.

At Blackwoods Interior, we believe homeowners should have a clear understanding of their renovation scope before committing to the project.

From space planning and design to carpentry, electrical, plumbing and renovation works, every component should be considered as part of the bigger picture.

Because renovation is not simply about spending more.

It is about spending wisely.

Frequently Asked Questions

How much does an HDB renovation cost in Singapore in 2026?

There is no fixed price because renovation costs vary according to the size of the flat, property condition, design, carpentry, materials and scope of works. A detailed quotation based on the actual project is more useful than relying on a generic package price.

What is usually the most expensive part of an HDB renovation?

Carpentry can be one of the largest components of an HDB renovation, particularly when homeowners require extensive built-in storage, wardrobes and kitchen cabinets.

How can I reduce my renovation cost?

Prioritise essential works, reduce unnecessary carpentry, choose materials strategically and finalise your design before renovation starts. Comparing quotations based on the same scope is also important.

Should I choose the cheapest renovation quotation?

Not necessarily. A lower quotation may have a smaller scope or exclude certain works and materials. Always compare the detailed inclusions and specifications rather than the final price alone.

Is it better to renovate everything at once?

It depends on your budget and requirements. Completing related renovation works together can sometimes improve coordination, but homeowners should prioritise essential works if their budget is limited.
