Construction & Renovation Guides: Costs, Permits and Phasing
Budgets, permits, sequencing and the real cost of building work. Every guide is checked against 2026 prices. For official reference, see nahb.org.
What the Construction & Renovation desk covers
This desk handles the messy middle of a building project: budgets, permits, sequencing, structural work and the decision between doing a job yourself and hiring it out. We cover extensions, kitchens, bathrooms and the work that must happen before finishes. The focus is on order of operations, because a correct sequence saves more money than a clever design detail and far more than a discount on tiles.
How we build a realistic budget
We price demolition, groundworks, structure, envelope, services and finishes as separate blocks, then add contingency before the first contract is signed. A budget without contingency is a wish. We compare quotes at the same scope and highlight allowances that quietly shift cost later. Where a project can be phased, we show the extra cost of temporary kitchens, repeated setup and price escalation between phases.
Where to start on a renovation
Survey the building before you design the room. Roof, structure, drainage and services come first, then layout, then finishes. Decide the whole-house plan even if you build in stages, so a future wall or bathroom stack does not undo work you have already paid for. Keep drawings, permits, photographs and warranties together. That file is what turns a finished project into a documented asset.
Use the cards below to compare the guides on this desk. Each card shows an editor score, a typical cost range and the subject the guide is built around, so you can sort by price or by recency without opening every page. The filters run in your browser and do not send anything to a server. If you are unsure where to begin, read the lowest-cost guide first, then move to the project that needs the bigger decision. Prices are checked against 2026 supplier and contractor data, and every guide names the sources behind its numbers. When a range looks wide, that is usually the honest answer: the same job can differ by thousands depending on access, location and the condition of the house.
