"How much will it cost to renovate?" is one of the hardest questions in construction to answer honestly — because "renovation" can mean anything from repainting a bedroom to gutting a house down to its frame and rebuilding. The price swings by a factor of ten depending on which one you mean. This guide gives you realistic 2026 per-square-meter ranges for each level of renovation, what actually drives the cost, and the two things — a permit and an engineer — that people skip and regret.
Renovation cost is driven less by floor area than by how deep you go — finishes only, or into the structure itself.
Before any number means anything, you have to know which tier you're in. Most renovations fall into one of three:
| Tier | Typical scope | Permit / engineer? |
|---|---|---|
| Cosmetic | Repainting, replacing finishes, fixtures, doors, minor tiling | Usually none |
| Mid-range | New kitchen & bathrooms, new flooring throughout, non-structural layout changes, rewiring/replumbing sections | Permit often needed for MEP & layout |
| Full gut / extension | Strip to the frame, add a floor or extension, move/remove structural walls or columns, new roof | Always — permit + engineer-sealed plans |
Before you demolish, AEDO assesses your existing structure and tells you honestly what the renovation involves — and whether it can carry an added floor or extension.

But the moment you alter the structure, add floor area, change the use, or touch electrical/plumbing/mechanical systems, you typically need a building permit and the relevant ancillary permits. Adding a second floor, a roof deck, or an extension, or removing a column or load-bearing wall, always requires engineer-sealed plans.
The most dangerous renovation we see is the added storey or roof deck on a house whose columns and foundation were only ever designed for what was originally there. It looks fine — until it isn't. Before adding any load, a licensed structural engineer has to confirm the existing structure and foundation can carry it, and design the reinforcement if they can't. This is not optional, and it's not where to save money.
The ranges above are indicative starting points for budgeting, not quotes. Renovation pricing depends on scope, location, finish quality, and — more than anything — the condition of what you're renovating. For new-build comparisons, see our house construction cost guide.
AEDO Construction assesses your existing structure, tells you honestly what your renovation will involve, and — for anything structural — provides the engineer-sealed plans and permit-ready documents. For full renovations and extensions, our design-build option puts design, permit support, and construction under one accountable contract.
Indicatively: cosmetic ₱3,000–8,000/sqm; mid-range (new kitchen/bath, finishes, some layout) ₱8,000–18,000/sqm; full gut or extension ₱18,000–35,000+/sqm, approaching new-build cost. Actual cost depends on scope, location, finishes, and the condition of the existing structure — treat these as starting ranges, not quotes.
Cosmetic work usually doesn't. But any renovation that alters the structure, adds floor area, changes the use, or affects electrical/plumbing/mechanical systems typically needs a building permit and ancillary permits. Adding a floor, removing a structural wall or column, or extending the footprint always needs engineer-sealed plans and a permit.
Yes, whenever the work touches the structure — adding a floor, extension, or roof deck, removing or relocating columns or load-bearing walls, or large new openings. Adding load the original structure wasn't designed for is a leading cause of renovation failures. An engineer checks whether the existing structure and foundation can carry the new loads and designs the reinforcement if not.
Hidden conditions found after demolition, scope creep, and starting without a complete design and bill of materials. Renovations carry more uncertainty than new builds because you inherit someone else's work — a 10–20% contingency and an assessment before demolition are the best protection.
AEDO Construction assesses your existing structure, designs any structural changes (signed and sealed), handles the permit, and — for full renovations and extensions — builds it under one design-build contract. No surprise change orders, no guessing what your house can carry.
