WHAT WE DO : AWARD WINNING KITCHEN EXTENSION DESIGNERS WIMBLEDON SW19

Capturing your vision
We apply innovative architectural design solutions to building projects to develop a concept design, sketching layout of your house extension and options to explore the potential of the property. We are prepared to spend as long as you require on this process, to ensure that all issues and alternatives are considered.

Bringing your ideas to life
Our creative Architectural & Interior designers will begin producing concept designs and sketches. This is a collaborative process where we work closely with you to develop ideas into a final set of plans for the kitchen extension build phase. You can also hand-pick materials, fixtures and fittings with guidance from our experts.

Construction and sign-off
You can look forward to the final result as the build teams begin construction under the orchestration of your personal Project Manager. The detailed program will ensure that the right people, tools and materials will be on-site at the right times for a seamless build.
Meet With Us
At the early stages of enquiry about your house extension project, most questions we receive are about feasibility and cost. We respond to this need by booking a free design consultation with a member of our Architectural Team. This consultation typically takes around 20- 30mins and following the meeting we will send you a tailored, fixed fee Design Proposal, along with an outline quotation for the works. If you prefer, we can also arrange a site visit to your home, and with our Premium visit the fee is refundable in full should you instruct us within 30 days of the visit.

High quality kitchen extensions Wimbledon
The kitchen is often referred to as the heart of the home, so the significance of this space isn’t lost on us. After all, it’s where many families tend to congregate, and a fantastic kitchen can be the very thing to make a house feel like a home.
That’s why we put 100% into every single kitchen extension project we undertake. At the early stages of your project, you will likely have some enquiries about the feasibility and expected costs of your plan, so we can arrange a completely FREE design consultation with a member of our Architectural Team. This will typically last between 20 and 30 minutes, and will allow us to develop a tailored, fixed fee Design Proposal, which will include an outline quotation for the works. This means that you don’t have to go into your project blind to the costs to your time and finances, and we can work together to make sure that all the work taking place falls within your budget.
That’s a big part of what we do here at Design & Build London: delivering high quality projects on brief, on time and within budget. We offer a wide range of kitchen extension, loft and basement conversion, refurbishment and home extension services in Wimbledon and the wider London/SW London districts.
Working in different areas and taking on projects in different house types is something we love. No challenge is too big or too small for our team.
