House Extensions Canterbury
Looking to extend your home in Canterbury? We design and build high-quality kitchen extensions, rear extensions, side returns and two-storey additions
High-Quality Extensions Built Around Your Home & Lifestyle
When your Canterbury home no longer provides the space your family needs, a house extension offers the perfect solution. Rather than facing the expense and upheaval of moving, an extension adds valuable room while keeping you in the location you love. We design and build single storey, double storey, side return, and wrap-around extensions across Canterbury, managing every stage from initial design and planning applications through to construction and finishing.
Whether you need a spacious kitchen-diner opening onto the garden, additional bedrooms and bathrooms above, a dedicated home office, or simply more room for a growing family, we deliver extensions tailored to your property and budget. Our team handles all trades in-house including structural work, bricklaying, roofing, plastering, electrics, and plumbing, so you deal with one team from start to finish. We build extensions that complement the existing property and add genuine value to your Canterbury home.
Types of Extensions We Build
Rear Extensions
Extend your Canterbury home into the garden with a expertly designed rear extension. Whether you’re creating an open-plan kitchen-diner in Wincheap, adding a family room in St Stephen’s, or opening up a Victorian terrace in St Dunstan’s, we deliver projects that transform how you live. Our team handles everything from planning applications through to final finishes, working with Canterbury’s mix of period properties and modern homes. We’ll help you maximise natural light with bi-fold doors or skylights while ensuring your extension complements your existing property. Most rear extensions fall under permitted development, meaning faster project timelines.
Side Return Extensions
Unlock wasted space with a side return extension. Many Canterbury terraces and semis have narrow alleyways running alongside the kitchen—dead space that’s perfect for extending into. A side return extension can add metres to your kitchen width, creating room for a breakfast bar, utility area, or larger cooking space. Properties in Nunnery Fields, along the Old Dover Road, and throughout Canterbury’s Victorian streets often suit this approach. We’ll design a layout that works with your existing structure while bringing in light through roof lanterns or glass panels.
Wrap-Around Extensions
Combine rear and side return extensions for maximum impact. A wrap-around extension gives Canterbury homeowners the best of both worlds—additional depth and width creating genuinely spacious ground floor living. This approach works particularly well for period properties in Oaten Hill and the streets around Canterbury West, where original kitchens are often compact. We manage the structural complexity, ensuring load-bearing walls are properly supported and building regulations are met. The result is a seamless, open-plan space that feels like it was always part of your home.
Single & Double Storey Extensions
Add serious square footage with single or double storey extensions. A single storey extension suits homeowners needing extra ground floor space without major structural work, while a double storey extension adds bedrooms and bathrooms above. Properties in Rough Common, Harbledown, and Tyler Hill often have the plot space for substantial extensions. We’ll advise on planning requirements, handle building regulations, and deliver a finished extension that adds both living space and long-term value to your Canterbury home.
