Expanding Your Living Space

As your family grows, your property needs to adapt. Moving house is expensive and highly stressful, making a bespoke home extension the perfect solution for creating the space you desperately need. As a highly experienced builder, FMT Construction Consultants Ltd delivers flawless single and double-storey additions for properties across Weybridge, Cobham, and surrounding areas.

Transforming the Heart of Your Home

One of the most popular reasons for expanding a property's ground-floor footprint is to create a stunning, open-plan culinary and dining area. We frequently tie our rear additions directly into a high-end kitchen refurbishment. This approach completely revolutionises how you use your home, delivering a bright, modern social hub tailored to clients in Esher, Oxshott, and neighbouring communities.

Executing Seamless Structural Alterations

Blending a new build phase seamlessly into your existing property requires absolute technical precision. We routinely manage the complex structural alterations needed to safely knock through rear exterior walls and install heavy steel supports. This guarantees a smooth, continuous flow between your original rooms and the newly constructed space, executed flawlessly across Walton on Thames and the wider region.

Integrating Complete Property Renovation

Undertaking a major rear, side, or wrap-around addition is the perfect catalyst to update the rest of your house. By combining your new build phase with a wider property renovation, we ensure that modern plumbing, updated electrical circuits, and fresh plastering run consistently throughout the entire building. Our comprehensive project management keeps these multi-phase builds entirely on track.

Exploring Alternative Expansion Methods

If your garden plot does not easily accommodate a traditional brick-built outward addition, there are plenty of other ways to increase your square footage. We are highly skilled at executing rapid garage conversions that repurpose underutilised attached structures into highly functional living areas. For our rural clients in Claygate, Shepperton, and surrounding areas, we also deliver spectacular barn conversions that add massive residential value without requiring entirely new foundations.

Looking Upwards for Additional Room

When expanding outwards is restricted by plot size, building upwards is the most logical next step. Alongside our extensive ground-floor work, our team is perfectly equipped to deliver a custom loft conversion that adds valuable bedrooms and en-suites to your property. Managing both ground-level and roof projects concurrently ensures maximum logistical efficiency for your overall build.

Questions and answers

House Extension Questions

Do I need planning permission for a house extension?

Many single storey rear extensions can be built under permitted development, within limits on size and height. Two storey extensions, side extensions facing a road and homes in conservation areas usually need a planning application. We check this at the first visit and manage the application for you.

Will an extension need building regulations approval?

Yes. Foundations, structure, insulation, drainage, fire safety and electrics are all inspected by building control as the work goes on, and a completion certificate is issued at the end.

Can we stay in the house while the extension is built?

In most cases, yes. The new structure is built outside the existing walls first, and the opening into the house is made near the end. We seal the work area and agree with you when the kitchen or services will be out of use.
