Loft Conversions in Surrey & SW London.

A garage conversion is typically the most cost-effective way to add living space, followed by rear extensions and loft conversions. The best choice depends on your property layout, how you want to use the space, and local planning constraints. We'll advise on the most cost-effective route at a free consultation.

Yes, we manage the whole planning process on your behalf, from architectural drawings and the planning or Permitted Development application through to structural engineering calculations and managing the building control process. We deal with local councils across Surrey and London, so you have one accountable team rather than several separate consultants.

Many loft conversions fall under Permitted Development and do not need full planning permission, though this depends on your property. Flats and maisonettes, conservation areas, and designs that exceed volume limits may require an application. We confirm the position for your address at a free loft assessment and manage any application with your council.

It depends on the type of conversion and the specification. Velux rooflight conversions are the most cost-effective where headroom already exists, while dormer, hip-to-gable and mansard work involves altering the roof structure itself and sits higher. The existing roof, the stair position and the head height you have to work with all move the figure, which is why we assess the loft before putting numbers to it. We then provide a fully itemised Cost Proposal, with weekly billing and no large deposits.

The main types are Velux rooflight, dormer, hip-to-gable and mansard conversions. The right option depends on your existing roof structure, headroom and any planning constraints, all of which we review at a free consultation. We also add en-suite shower rooms and bespoke staircases designed to meet building regulations for headroom, pitch and fire safety.

A standard loft conversion typically takes 6 to 10 weeks from start to completion, with more complex mansard conversions taking 10 to 14 weeks. Most of the structural work is carried out from scaffolding, so daily life continues largely as normal. We agree the programme with you before work begins and bill weekly against completed stages.

A loft conversion adds a full floor of usable living space, most often a bedroom with an en-suite, and that additional space is usually reflected in what a home is worth. The effect varies by property, location and finish, so we would always suggest speaking to a local estate agent about your own street.

Most loft conversions require new floor joists to meet building regulations, steel beams for structural support, and modifications to the existing roof structure. A dormer or mansard conversion involves cutting into and rebuilding sections of the roof. We handle all structural engineering calculations and building regulations submissions.

Yes, every loft conversion needs building regulations approval, whether or not planning permission is required. Approval covers structural integrity, fire safety including a protected staircase, insulation, electrics and glazing. We commission the structural engineer's calculations, make the submissions, arrange the inspections and manage the project through to building control sign-off, all as part of the project.

Most of the structural and external work is carried out from scaffolding without major disruption. Internal work such as staircases, plastering, and electrics will require some adjustment to daily routines. A typical dormer conversion takes 6 to 10 weeks. We plan the programme to minimise inconvenience and keep you informed at every stage.

A dormer conversion extends outward from the existing roof slope, creating additional headroom and floor space, ideal for most property types. A hip-to-gable conversion extends the sloping side of a hipped roof to create a vertical gable wall, maximising loft space on semi-detached and detached properties. We assess your roof during a free consultation to recommend the best option.
