A villa renovation is not simply a larger apartment renovation. It involves more systems, more exterior elements, more trades, and above all, more unknowns — because behind any wall in an existing structure, something unexpected may be uncovered that was never on the plans. That is why these projects almost always fail in management, not execution.
Stage Zero: Knowing What You Have
Before you plan, you inspect. A condition assessment of an existing villa includes inspecting the structural framework, roof condition and waterproofing, the age and integrity of the electrical and plumbing systems, and checking for moisture. A single day of work at this stage saves weeks on average later on. Skipping it is the most common cause of mid-project "surprises." See renovating an old building.
Sequence of Work
- Demolition and clearance — Down to the bare structure, including authorized waste disposal.
- Structural work — Wall openings, structural reinforcement, additions. See structural reinforcement.
- Building envelope — Roof waterproofing, windows, insulation. Everything before touching the interior.
- MEP infrastructure — Electrical, plumbing, sewage, HVAC, communications.
- Interior finishes — Drywall, plaster, wet area waterproofing, tiling, spackling, and painting.
- Millwork and final systems.
- Site development and landscaping — Exterior paving, garden, pool, pergola, fencing.
- Handover against a punch list.
The most frequently broken rule: The envelope before the interior. Flooring installed before the roof is sealed is flooring that will end up being ripped out.
A Realistic Timeline
For a comprehensive renovation of a 250–400 sqm villa: seven to twelve months. Demolition and structural work 4–8 weeks, envelope 4–6, utilities and infrastructure 3–5, interior finishes 12–18, exterior development 6–10 weeks in parallel. These estimates assume decisions are made on time and long-lead orders — aluminum systems, custom millwork, imported tiling — were finalized early on.
Where the Money Goes
- Structural work. Opening any load-bearing wall requires engineering design, reinforcement, and specialized execution. This is the least predictable line item.
- Aging systems. Replacing infrastructure in a 1990s villa is almost always essential, yet rarely budgeted upfront.
- Exterior and grounds. 15% to 25% of the total budget, and the item most people defer to "later."
- Finish specifications. Natural stone, architectural millwork, and smart home systems — this is where the cost differential between villas lies.
A proper contingency reserve for a villa renovation is 15% to 20%, not 10%.
Day-to-Day Management
Four tools are sufficient: a daily site log, a decision tracking schedule highlighting when pending decisions cause delays, quantity tracking against the bill of quantities at every stage, and written approval for every variation prior to execution.

Project Handover
Handover is a formal process, not a casual walkthrough: a room-by-room inspection, a numbered punch list with photos and target resolution dates, a remediation round, reinspection, and only then final payment. See also warranty on finishing work.
Frequently Asked Questions
Can you live in the villa during the renovation?
During a comprehensive renovation — it is not recommended. Phasing work wing by wing is possible, but it extends the timeline by roughly 40% and increases costs, as each zone must be sealed off and reopened sequentially.
Is a building permit required?
Interior renovations without structural changes usually do not require a permit. Adding floor area, modifying the facade, creating openings in load-bearing walls, or altering the roof structure — yes. See building permit.
