Innovative Extensions Crafted with Exceptional Architecture


Our Chiswick architects create smart, sustainable extensions that suit your space perfectly.

Wraparound Home Extension

Wraparound


We specialise in wrap-around extensions. This is a popular way to expand and transform properties. This extension combines a rear and side addition. It creates an L-shape that expands ground-floor space. This is ideal for open-plan kitchens, living spaces, or adaptable rooms that fit modern lifestyles. We handle everything from design and planning permission to construction.

Single Storey Home Extension

Single Storey


A single-storey extension can really boost space in your Chiswick property. It can be added to the back or side of the property. This addition offers more space for a modern kitchen, a living area, or a home office. This extension improves the flow inside and makes the property more practical. Our architectural team makes it easy for you to get great results that suit your property.

Multistorey Extension

Multi Storey


A multi-storey extension in Chiswick can provide a lot of space. You can use it for extra bedrooms, bigger living areas, or more bathrooms. Building up on your property lets you make the most of it without losing any garden space. We take care of everything. This includes planning, permissions, and construction. We ensure your extension fits well with the current architecture.

Side Return Home Extension

Side Return


A side return extension utilises the unused space beside your home. You often find this addon in Victorian and Edwardian buildings in Chiswick. Clients can extend into this narrow area to make a wider, open-plan kitchen. This change will let in more natural light. Our architects are experts in side return extensions. These designs boost functionality and add to the property’s value.

Rear Home extension

Rear Extension


A rear extension expands the back of your property. This gives you room for an open-plan kitchen, a larger dining area, or a more spacious living room. This is ideal for clients looking to improve their ground floor. These extensions boost natural light and link indoor and outdoor spaces smoothly. We create rear extensions that match your home’s style. They also boost efficiency and value.

FAQ

An architect is required for extensions, as they deal with planning detailed drawings that are essential considerations.

Some individuals do entrust contractors with project design and construction, but this approach can come with risks.
Having an architect involved in renovations ensures that your home addition is compliant with regulations, although there’s no legal requirement to hire one for any project.

There’s no legal requirement to involve an architect in your application for your extension’s planning permission.

That being said, architects can be incredibly useful and save you a lot of time and money in the long run for moving your extension ahead.

While architects are not required to offer their services for free, we do not charge for an initial consultation. This initial meeting allows for a discussion about your project requirements. However, you should anticipate paying for any detailed design or advice beyond this initial conversation.

Typically, from engagement, we aim to produce draft documentation within a 14-day period.

Modern Space in a Historic Setting: Chiswick Extensions

With leafy streets, Georgian villas, and a village-like feel, Chiswick House & Gardens at its heart, Chiswick offers a calm and characterful place to live. From family homes around Turnham Green to riverside terraces in Strand-on-the-Green, the area is suited for well-designed, lifestyle-enhancing residential extensions.

Why Chiswick Homes Are Perfect for Tailored Extensions

Chiswick blends historic charm with a strong sense of community. Homes in areas like Bedford Park homes often have extensions for open-plan kitchen and dining areas. They can add bedrooms by converting lofts or creating new basements in older houses. They do this while keeping their original charm.

(Wikipedia – Chiswick)

Streets like Rusthall Avenue, Grove Park Road, and Fauconberg Road have many properties. These homes are great for stylish extensions that can add value. Many are in conservation areas, so careful design and planning are key for success.
