Bespoke Home Extensions

More than an extension. A seamless evolution of your home.

Most builders can add a room. At Whitley Builders, we specialise in architectural extensions that feel like they were always part of the original design. From expansive glass-fronted kitchen-diners to multi-storey additions, we blend heritage craftsmanship with modern engineering to create spaces that define the way you live. 

Architectural Glass & Rear Extensions

Open your home to the outdoors. We specialize in large-format glazing, bi-fold installations, and structural steelwork that creates breath-taking, light-filled, open-plan living areas.

Multi-Storey Additions

When you need significant square footage without compromising your garden, a double-storey extension offers the ultimate transformation—adding master suites, dressing rooms, and vaulted ceilings that add immense value to your property.

Heritage & Conservation Integration

Working on a period property in Reigate or a character home in Tadworth requires a delicate touch. We source matching materials and utilize traditional masonry techniques to ensure your extension respects the history of the building.

Design-Led Construction

We work in close partnership with your architects or our own design partners to ensure every detail—from the placement of a skylight to the finish of the floor—is executed to perfection.

Turnkey Management

We handle the complexities of Surrey planning departments, structural engineering, and site management. You get one point of contact and a project delivered on time, with zero hidden surprises.

Fixed-Price Transparency

As detailed in our [Homeowner Guides], we don't believe in the "low-ball" estimate. We provide comprehensive, transparent quotes that reflect the true cost of premium craftsmanship and high-quality materials.
