WHAT WE DO

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.

Why Choose Design & Build London?

Transparency

We believe that the key to a strong working relationship is transparency. That is why we produce a full schedule of works that breaks down the project into simple weekly targets that correlate to payments, making it clear what to expect.

Liaison

It is vital to the success of a project that we have a clear channel of communication with our clients. A Project Co-ordinator will be assigned to you when the first draft plans are produced and will work with you right through to the completion of the building works. They will be your main point of contact throughout the process.

Carefully managed

We have worked hard to build a strong work force that represents Design & Build London in the best possible light. Our Project Co-ordinators are articulate, organised and approachable, whilst our site foremen are experienced and reliable. In order to attract and retain the very best workmen we make sure we give them the training and tools they need.

First-class Service

Residential building work requires a high level of attention to detail. Creating a great structure isn’t enough, its the cosmetic elements that everybody looks at and talks about, we take pride in the plastering, brickwork, rendering and roofing so that our product has a distinct feel that is reflected across all of our projects.

Recommendations

We are a small business that relies on recommendations; we don’t just want our customers to walk away satisfied, we want them to actively tell their friends and family about the positive experience they have had with us. We always sit down with our customers at the end of each project to ask for feedback as we constantly strive to improve.

We are Your partner

More than 30 years’ experience underpins our reliable and detailed approach to every project. Our proficient team provides efficient project management while adding value at every stage of the process from design to completion.
