Renovations fail on postponed decisions, not on tiles
The most expensive part of a renovation is not materials but rework. Rework comes from decisions made too late: the socket moved after plastering, the bath chosen after the tiling, the washing machine bought once the recess was already built to different dimensions.
So preparation is mostly about decisions made before the work starts, and about documents fixed at the outset. After that the renovation becomes the execution of a plan rather than a series of improvisations.
What to decide before the first hammer blow
| Decision | What it determines |
|---|---|
| Scope of work, room by room | The budget, the timeline and where you will live |
| Furniture and appliance layout | Sockets, water outlets, connection heights |
| Specific models of large appliances | Recesses, dimensions and connections — before, not after |
| Floor and wall finishes | The order of works and the screed thickness |
| Who does the work | Timescales, responsibility, payment schedule |
A list of appliance models with exact dimensions is the most underrated item here. A recess for a built-in dishwasher built “roughly” leads to buying a different dishwasher.
About money and time
A contingency reserve is always needed, because opened walls and floors reliably deliver surprises: old wiring, uneven slabs, traces of past leaks. Keep the reserve separate from the budget and do not spend it on “while we are at it”.
Fix the timeline in stages rather than as a single completion date. A stage that slips is visible immediately; a single end date keeps lying to you until the final week.
The documents that save you later
A contract with a costed schedule and payment terms. Photographs of the flat before the work. And above all, photographs of concealed work before it is covered: wiring and pipes in walls and floors, shot with recognisable reference points. A year later, when you want to hang a shelf or trace a leak, those photos are worth more than any manual.
Neighbours and building rules
Permitted hours for noisy work, rules for construction waste, lift use, approvals for structural changes — these vary by building and country, and are better learned before you start than after the first complaint. Neighbours who were warned are far more tolerant of unexpected noise.
When preparation is complete
The scope is described, the layout is approved, appliances are chosen with dimensions, the contract is signed, the current state is documented, neighbours are warned, waste removal is arranged, the reserve is set aside and the acceptance stages are scheduled. After that a renovation becomes a project with a plan rather than an endless building site.
