A 138 sqm home is usually a large family residence, so renovation cost varies widely. The budget depends on the amount of layout change, material level, cabinetry, bathrooms, furniture, and whether the home must serve several generations.
HOMESEE-Decor helps project owners think beyond one number by connecting cost with design scope, material grades, and room-by-room requirements.
Quick Answer
For a 138 sqm renovation, estimate cost by finish level, then review layout changes, active and quiet zones, family member needs, material grade, storage, bathrooms, and delivery or installation responsibilities.
Understand Budget Levels
Low-to-mid, mid-range, upper-mid, and premium renovations can differ mainly in hidden work, cabinetry, bathroom fixtures, flooring, doors, lighting, and furniture. Make sure quotes describe the included scope clearly.
Review the Layout Before Choosing Materials
Large homes often benefit from adjusting non-load-bearing partitions, storage walls, or door positions. Layout decisions should come before finishes because they affect quantities and construction sequence.
Separate Active and Quiet Zones
Living room, dining room, kitchen, guest bathroom, and circulation are active zones. Bedrooms, study, and private bathrooms are quiet zones. Reducing overlap improves daily comfort.
Design for Different Family Members
Children, older adults, remote workers, and frequent guests may need different safety, storage, lighting, and acoustic decisions. A large home should not be planned as one generic space.
Choose Material Grades Strategically
Use durable materials in high-traffic and wet areas. Softer decorative upgrades can be used in lower-risk spaces where replacement is easier.
HOMESEE-Decor Planning Note
For overseas owners, designers, developers, and contractors, HOMESEE-Decor can help turn a broad renovation idea into a clearer project package: room-by-room scope, material direction, finish references, quantity discussion, sample coordination, and sourcing support from China. Local code compliance, structural decisions, utility connections, and final installation should still be checked by qualified professionals in the project location.
Final Thoughts
A 138 sqm renovation cost is easier to control when each cost decision is tied to layout, family use, and material performance.
