A 115 sqm home is often large enough for three bedrooms, two living zones, or a comfortable family layout. That also means the renovation has more systems to coordinate: demolition, plumbing, electrical work, kitchen planning, bathroom waterproofing, wall finishes, sockets, lighting, and final installation. A clear process prevents cost surprises.
Quick Answer: How Much Does a 115 sqm Home Renovation Cost?
The cost of a 115 sqm home renovation depends on whether you choose a half-package model or a full-package model, plus the grade of main materials, furniture, appliances, and custom cabinetry. A half-package renovation usually lets the homeowner buy main materials while the contractor handles labor and auxiliary materials. A full-package renovation includes more purchasing and coordination through the renovation company.
Half Package vs Full Package
| Model | What It Usually Means | Best For |
|---|---|---|
| Half package | Contractor handles labor and basic auxiliary materials; homeowner buys main materials | Owners who want cost control and material choice |
| Full package | Contractor manages more materials, labor, and installation coordination | Owners who prefer convenience and one project manager |
Step 1: Demolition and Structural Modification
The renovation normally starts with demolition and modification work. This may include removing non-load-bearing walls, building new partitions, stripping old wall surfaces, replacing windows, or removing old heating elements. Waste should be cleared quickly so later construction can proceed safely and cleanly.
Step 2: Plumbing and Electrical Planning
Before plumbing and electrical work begins, confirm the kitchen layout, bathroom fixtures, washing machine location, lighting positions, switch height, socket quantity, and appliance needs. If a water heater, air conditioner, or built-in appliance has special requirements, plan power and pipe locations before walls are closed.
For bedrooms, avoid placing an air conditioner so that it blows directly toward the bed. For kitchens, add enough switched sockets so daily appliances do not need constant unplugging.
Step 3: Wall Finish and Wallpaper Timing
Wallpaper can create a warmer effect than paint in selected areas, but timing matters. The wall base should be properly treated, primer should dry, and the room should be protected from excess dust before installation. Use wallpaper as a feature rather than covering every room if the budget is tight.
Step 4: Socket Panels and Final Hardware
Socket panels are usually installed after major wall work. Choose reliable switches and sockets, and use switched outlets in the kitchen where possible. This makes rice cookers, microwaves, kettles, and small appliances safer and easier to manage.
Light, Air, and Layout Still Matter
A comfortable 115 sqm home needs good daylight, ventilation, and circulation. Dark homes often feel less healthy and less pleasant to live in, while layouts with doors directly facing balconies or awkward kitchen positions may need screens, cabinets, or layout adjustments. Treat these as design comfort issues, not only style choices.
Final Thoughts
A successful 115 sqm renovation depends on sequence. Confirm the budget model, complete demolition safely, plan plumbing and electrical work early, install finishes in the right order, and check every detail before moving to the next stage. This keeps the project easier to control from first quote to final move-in.
