— Our Process
How It Works
Site survey & design
A structured survey by our building team assesses foundations, roof lines and party wall requirements. We produce feasibility sketches, coordinate with structural engineers and advise on planning or permitted development.
Foundations & structural works
Groundworks, reinforced foundations and any necessary steel or masonry alterations are carried out by our builders under engineer specification to ensure long-term stability.
Fit-out & handover
Plastering, joinery, electrics and finishing bring the space together, with all services integrated as we go. You get a ready-to-use room, a formal handover and clear maintenance guidance.

Why Choose us for Extensions?
Single partner for build + services
With building and plumbing/heating divisions in-house, trades are coordinated on site rather than chased between contractors, so radiators, drainage and any boiler work happen at the right point in the programme, without delays.
Four decades of experience
Forty years' combined industry know-how across Surrey, Sussex and London, bringing robust methods, reliable project management and real attention to finish, from rooflight detailing to bi-fold door thresholds.
Compliance and quality guarantees
Building regulations submissions, structural calculations and party wall agreements all handled, with any gas work carried out by Gas Safe registered engineers.
Design-led build for lasting value. Extensions should feel like they were always part of the house. We start with a detailed site survey and CAD-led drawings, take care of building regulations submissions and structural calculations, then programme the works to suit your family and your access. Typical projects include single and double-storey rear extensions, side returns, wrap-arounds and dormer loft conversions, with options for Velux or full dormer roofs.
Practical integration of services. The parts you never see are the parts that matter most. We handle groundworks, reinforced foundations, drainage runs and structural steel to engineer specification, tying the new build cleanly into the existing structure so it stays stable and watertight for decades. Trades are sequenced properly, so nothing is rushed and nothing gets undone later. To arrange a free site visit, call 01342 545 065 or email info@aspirebuildingandproperty.co.uk.

Frequently Asked Questions
Timescales depend on scope: single-storey rear extensions are quicker than double-storey or loft conversions that require structural work. Once we assess site access, foundations and structural requirements we provide a project schedule and key milestone dates so you know when each trade will be on site.
