Expertly built house extensions across Brighton, Hove and East Sussex. From single storey rear extensions to full two storey builds — one contractor, fixed price, managed start to finish.
A well-designed house extension is the most effective way to gain the space you need without the cost and disruption of moving. At Pearce Property Services we help to design, build and fully manage your extension as your single point of contact — from foundations to finishing touches.
We build extensions across Brighton, Hove and East Sussex, bringing over 20 years of hands-on experience to every type of project — from side return extensions on Victorian terraces in Seven Dials and Preston Park, to large rear extensions in Hove, to two storey builds across Worthing, Lewes and Burgess Hill. Groundworks, structural steelwork, brickwork, roofing, electrics, plumbing, plastering, joinery and decoration — all under one fixed-price contract, managed start to finish.
Repair of a single-storey rear extension — structural steelwork, bi-fold doors, underfloor heating, a new kitchen and full decoration.
Every property has different constraints and potential. Whether you need a modest side return or a full two storey build, we design and construct extensions that work with your home, not against it.
Rear or side single storey extensions to create additional living space, open-plan kitchens or ground-floor bedrooms. The most popular extension type across Brighton and Hove.
Reclaiming the narrow alleyway alongside terraced and semi-detached properties to widen kitchens and living areas. Ideal for Brighton's Victorian and Edwardian terraces.
Combined rear and side return extensions maximising your ground-floor footprint. Creates the largest possible open-plan layout without going to two storeys.
Purpose-designed kitchen extensions with structural openings, underfloor heating, integrated utility spaces and room for dining. The most requested extension we build.
Ground-floor or first-floor bathroom extensions creating larger family bathrooms, en-suites or fully accessible wet rooms. Plumbing, tiling and waterproofing all included.
Converting and extending existing garages into habitable living space with full insulation, damp proofing, heating and natural light. Often achievable under Permitted Development.
Self-contained annexes for multi-generational living, home offices or rental income. Fully serviced with independent access, kitchen, bathroom and private entrance.
Double storey extensions adding significant space over two floors — bedrooms and bathrooms above, kitchen or living space below. Maximum value per square metre.
