Change the product, not just the finishes.
Renovation cannot change the address, floor or view. It can change how well the apartment works. Start with usability before choosing kitchens, bathrooms and finishes.
Start with the floorplan.
An older 120 sqm two-bedroom with a maid’s room, enclosed kitchen and oversized corridor might become:
- Two comfortable bedrooms and a home office.
- A larger living and dining area.
- Proper laundry and storage.
The floor area stays the same. The usefulness changes.
A better living space.
- Reclaim unnecessary corridors and partitions to improve living space and daylight.
- Add a bedroom only if it has proper proportions, natural light and privacy.
- Removing a bedroom can work when the improvement in living quality suits the target buyer.
- An open kitchen needs useful storage, worktop space and effective extraction.
Bathrooms have a strong visual impact.
- Replace dated fittings, but fix the layout and waterproofing first.
- Consider an ensuite or separate guest WC where it improves daily use.
- A walk-in shower can be more useful than an old tub—but retain a bathtub when the target family or luxury market expects one.
Make room for everyday life.
- Plan a dedicated place for washing, cleaning supplies, luggage and shoes.
- Provide enough sockets, good lighting and suitable air-conditioning.
- Solve noise problems with appropriate glazing before spending on decorative upgrades.
- Preserve flexibility: a home office should not make the remaining rooms unusable.
Ceiling height can be more valuable than ceiling design.
- Removing unnecessary suspended ceilings can reveal valuable height.
- Restore worthwhile original parquet rather than covering it with inexpensive laminate.
- Choose finishes that fit the building and its market; higher cost does not guarantee higher value.
Renovation Value Matrix for Bangkok
The + scale is an indicative comparison of potential impact, not a predicted price increase or guaranteed return. Results depend on the existing unit, workmanship and target market.

Things that can actually decrease value
Over-design and reduced flexibility can destroy value. Common mistakes include:
- Removing a bedroom without creating substantially better living quality.
- Creating bedrooms without windows.
- Making bedrooms too small for normal furniture.
- Excessive built-ins that dictate how rooms must be used.
- Removing too much storage.
- Eliminating the washing-machine position.
- An open kitchen without adequate extraction.
- Putting the washing machine prominently in the kitchen.
- Removing the only bathtub from a family-oriented luxury apartment.
- Too many different materials.
- Very personal colors or design.
- Low ceilings caused by unnecessary gypsum ceilings.
- Dark rooms created by new partitions.
- Sacrificing living room width to create an additional room.
- Fake-luxury finishes.
- Cheap laminate over good original parquet.
- Poor bathroom waterproofing.
- Moving wet areas into technically risky positions.
- Insufficient AC capacity.
- Beautiful design but insufficient sockets, storage or lighting.
Renovation should solve problems first.
- Identify the weaknesses: dark rooms, wasted circulation, poor privacy, noise or missing storage.
- Fix those problems before adding premium materials and decorative features.
- Check technical feasibility and required building approvals before altering windows, wet areas or balconies.
The biggest value creator: a better property.
Spending THB 1 million does not automatically add THB 1 million in value. Prioritize better layout, proportions, daylight, storage, acoustics and functionality—with finishes appropriate to the market.
At CondoGuru, we look at the floorplan before the finishes. A better home starts with better space.
