Introduction

Our Extension Services

At Hill & Way, we design and deliver thoughtfully executed structural home alterations across London's most prestigious neighbourhoods. Whether you're extending a Victorian terrace, enhancing a Georgian townhouse, reconfiguring a grand stucco-fronted home or expanding a detached Edwardian property, we create thoughtful, architecturally sensitive spaces that feel like they have always belonged.

Managing every stage of the project under one roof, we partner with homeowners, architects and interior designers to deliver seamless extensions from concept through to completion.

No two homes are the same, which is why every extension is tailored to the property, its architecture and the aspirations of the homeowner.

Our expertise.

Our expertise includes:

Rear Extensions

Create larger, brighter living spaces that seamlessly connect your home with the garden through carefully considered layouts and expansive glazing.

Side Return Extensions

Unlock the unused potential of narrow side passages, transforming dark, confined layouts into spacious open-plan kitchens and family living areas.

Wraparound Extensions

Combining rear and side return extensions to completely reimagine the ground floor, creating generous, light-filled spaces designed for modern living.

Double-Storey Extensions

Expand both ground and first-floor accommodation while maintaining a balanced architectural appearance and maximising the value of your property.

Structural Alterations

From removing load-bearing walls and installing structural steelwork to completely reconfiguring internal layouts, we create open, flowing spaces without compromising structural integrity.

Designed around your home

Every property presents its own opportunities and constraints. Whether we're extending a grand stucco-fronted Victorian terrace in Chelsea, reconfiguring a Georgian townhouse, enhancing an Italianate villa or creating additional family space within a detached Edwardian home, every extension is carefully designed to complement the original architecture while improving everyday living.

Frequently Asked Questions

Answers for clients considering house extensions.

What types of house extensions do you undertake?

We deliver rear extensions, side return extensions, wraparound extensions, double-storey extensions and bespoke structural reconfigurations. Every extension is individually designed around your property, lifestyle and long-term aspirations, ensuring the finished space integrates seamlessly with your home.

Do I need planning permission for a house extension?

Planning permission depends on the size, design and location of your extension. Some extensions can be completed under Permitted Development rights, while others require full planning consent. We work closely with architects, planning consultants and local authorities to guide you through the process and ensure all necessary approvals are secured before construction begins.

Can you work with my architect or interior designer?

Yes. We regularly work alongside architects, interior designers, structural engineers and quantity surveyors on luxury residential extension projects throughout London. Our collaborative approach ensures every design is delivered with precision while maintaining clear communication and careful coordination throughout the build.

Can you undertake structural alterations?

Yes. We specialise in complex structural alterations as part of house extensions and residential refurbishments. Our expertise includes removing load-bearing walls, installing structural steelwork, creating open-plan living spaces and reconfiguring existing layouts. All structural works are carried out in collaboration with qualified structural engineers and in full compliance with current Building Regulations.

Can I continue living in my home during the works?

In many cases, yes. Whether you can remain in your home depends on the scale and complexity of the extension. During the planning stage, we’ll discuss the construction programme with you and advise whether occupation is practical, ensuring disruption is kept to a minimum wherever possible.

We deliver luxury house extensions throughout Notting Hill, Chelsea, Kensington, Hampstead, St John’s Wood, Knightsbridge, Belgravia, Brompton and the surrounding areas of London. If your project is located elsewhere in London, we’d be happy to discuss your requirements.
