What we specialise in

Rear Extensions

Typically stretching across the back or side of your house, single-storey extensions are the go-to choice for expanding kitchens or creating dedicated playrooms. We often install wide bi-fold doors to erase the boundary between your indoor life and the garden.

Side Return Extensions

A side return is a clever way to gain internal width by reclaiming the underused alley alongside your house. This is a high-impact, low-disruption solution that preserves your precious backyard space. Because it uses existing boundaries, it is often a faster and more budget-friendly way to significantly change the feel of your ground floor.

Wraparound Extensions

By merging a side and rear extension, we create an expansive L-shaped floor plan. This is the ultimate choice for those wanting to enlarge an existing kitchen while simultaneously adding a brand-new dining or living area. The planning and roofing considerations generally mirror those of a standard single-storey build but offer much more dramatic results.

Multi-Storey Extensions

A double-storey build mirrors the footprint of a ground-floor extension but adds a second level of living space. It is the most effective way to add bedrooms and bathrooms without losing more garden space. While this adds the most value to a home, we work carefully to manage planning permissions and ensure the design respects the privacy of your neighbours.

Porch Extensions

A well-designed porch is a smart investment that boosts curb appeal and provides a practical thermal buffer for your home. It offers a dedicated spot for shoes and coats, keeping your main hallway clutter-free. In many cases, if the porch is kept under a certain size and separated by an internal door, it can be built without the need for formal planning permission.

Bungalow Upgrades and Over-Structure Builds

An over-structure extension allows you to build upwards, such as adding a new floor above an existing garage or bungalow. This is becoming a favourite for homeowners who want to keep their entire garden intact. This method often allows for more architectural creativity in the layout and is generally less messy than digging new ground-floor foundations.

Why is Pinnacle Design & Build the leading building contractor in Ewell?

We take full ownership of your project from the first sketch to the final brick. Our management includes navigating the planning-permission maze, overseeing structural engineering, coordinating with building control, and providing a dedicated project manager who delivers daily updates on our progress.

Investing in a Pinnacle extension offers impressive financial rewards, often boosting a property's valuation by up to 25 per cent. It is a secure and profitable way to improve your lifestyle while securing your financial future.
