High-quality residential extensions, renovations and structural alterations.
Book a Project ConsultationBarnet projects frequently combine additional floor area with substantial changes to the existing layout. AT Bespoke Build manages the extension, structural and renovation elements as one construction programme, helping homeowners retain control of specification, sequencing and cost decisions.
Why AT Bespoke Build
Access, neighbouring properties, party wall interfaces and the condition of the existing building can materially affect a Barnet project. Early review of temporary works, steel installation, drainage, service routes and retained finishes reduces avoidable changes once work is under way.
The portfolio evidence below is presented in its genuine project location and demonstrates the scale and construction capability relevant to a Barnet brief.
Case study£300k–£400k extension and renovation evidenceQuestions homeowners ask
For a project around this level, look for a main contractor with evidence of managing comparable values and combined structural, extension and renovation scopes. AT Bespoke Build’s supplied portfolio includes a £300,000–£400,000 extension and whole-house renovation in Enfield, presented as evidence of scale—not as a Barnet project.
Cost depends on size, structure, access, specification, existing condition and how much of the original house is renovated. A simple extension should not be compared directly with an extension plus structural remodelling or a whole-house project. Use the cost guide for indicative planning context.
The current portfolio records extension and renovation programmes from about seven to fourteen months depending on scope. A reliable programme requires design information, planning status, structural detail, specification and an assessment of site constraints.
House extensions, home renovations and structural alterations can be coordinated under one main-contractor programme where the project scope requires it.
