HAMMERSMITH'S Trusted House Extension Experts
Specialising in high end home renovations across London
At Unique Design & Build, we specialise in creating beautiful, functional house extensions that transform the way you live. From open-plan kitchen spaces to multi-storey additions, we’ve helped homeowners across London make the most of their homes, adding space, light and value with every project.
Our experience covers all types of extensions from modern, glass-fronted additions to more traditional styles that complement period homes. Our focus is always on creating something that feels truly unique to you.




TRANSFORMING HOMES ACROSS HAMMERSMITH
At Unique Design & Build we work closely with you from the first idea to final completion, ensuring your new space feels seamless and truly part of your home.
We design and build a wide range of extensions, tailored to suit your home and lifestyle:
Rear Extensions – Perfect for opening up your kitchen and dining space, bringing in natural light and a stronger connection to the garden.
Side Return Extensions – A popular choice for period homes in Chiswick, maximising unused alleyway space to create a bright, open-plan layout.
Wrap-Around Extensions – Combine rear and side elements for a full transformation and incredible impact.
Double Storey Extensions – Add both living and bedroom space for growing families or multi-functional homes.
Kitchen & Dining Extensions – Create the true heart of your home - a social, light-filled area for cooking, entertaining and relaxing.

HOW WE WORK
Unique Design & Build have extensive experience working in Hammersmith and nearby areas such as Brook Green, Brackenbury Village and Ravenscourt Park. We’re familiar with the mix of traditional Victorian and Edwardian homes alongside contemporary apartments, as well as the planning guidelines set by the London Borough of Hammersmith & Fulham.
With UDB, you’ll have a team that understands the character of Hammersmith’s homes and how to enhance them through thoughtful design and quality build work. From extensions and loft conversions to full refurbishments, we create spaces that balance modern living with the architectural charm of West London.
