Planning a house extension usually involves more than finding one builder.

​

Depending on the size and complexity of the project, you may need support from structural engineers, Building Control / Approved Inspectors, Party Wall surveyors, asbestos surveyors, builders, shell-build contractors, steel fabricators, scaffolding companies, skip hire providers, window and door suppliers, kitchen companies, bathroom specialists and other trades.

​

Some homeowners choose one main contractor to manage the whole project. This is often the quickest and simplest route, but it can also be the most expensive because the builder may add a margin to labour, materials, subcontractors and specialist services.

​

Another option is to appoint a builder for the main shell and obtain separate quotes for selected parts of the work, such as skips, scaffolding, steels, windows, doors, kitchens, bathrooms, electrics, plumbing, heating, plastering, tiling, flooring and decorating. This can sometimes help homeowners reduce costs and gain more control over the specification, although it usually requires more organisation.
