House Extensions

Expand Your Home with Our Expert Extension Services

At Pro Builder, we specialise in creating bespoke house extensions that cater to every unique requirement and lifestyle. Our team, led by the experienced project manager Tim Rigg, is dedicated to transforming your home with extensions that seamlessly integrate with your existing property.

An Extension You Can Be Proud Of

Each project is meticulously designed and executed to ensure that your new space is not only functional and beautiful but also a feature you’ll be proud to showcase.

Single Storey House Extensions

Ideal for expanding your living space horizontally, single-storey extensions are perfect for adding larger kitchens, dining areas, or additional rooms like utility spaces, home offices, or guest bedrooms. These extensions offer versatility in design, allowing for features like bi-folding doors to connect your home to the garden​.

Double Storey House Extensions

Double the space with our two-storey extensions. These are cost-effective solutions for adding significant living space, including extra bedrooms or bathrooms, while maintaining the property’s footprint. Recent changes in permitted development rights may also reduce the need for full planning applications for these extensions.

Over-Structure House Extensions

Built over existing structures, such as garages, these extensions are excellent for adding space without impacting your garden area. They require careful structural calculations to ensure safety and compliance.

Rear Extension (1)

Rear House Extensions

Extend into your garden or courtyard with our rear extensions. These are popular for creating open living spaces that blend the indoors with the outdoors, perfect for modern lifestyle needs​​.

Side Return House Extensions

Utilise the unused space along the side of your property with side return extensions. These transform alleyways into valuable living areas, ideal for enlarging kitchens and creating brighter, more open spaces.

Wraparound House Extensions

Combining side return and rear extensions, our wraparound extensions create substantial ‘L-shaped’ living areas. This style is particularly suited for properties with enough side and rear space, offering extensive room for creative design.

Timber Pagoda

Dormer House Extensions

Transform unused attic space with dormer extensions. This type often falls under permitted development rights and is an affordable option for adding bedrooms or playrooms.

Glass Roof House Extension


Blend traditional and conservatory styles with our orangery extensions. Designed with brick pillars and glass roofs, they are versatile spaces suitable for dining rooms, playrooms, or offices, offering a more open-plan feel than average extensions.
