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.

We are confident that you will warm to our trustworthiness, our professionalism and our creativity. You will be impressed with our modern approach and our ability to deliver your vision within agreed budgets.
We deliver exceptional results through our close attention to your requirements, allied to our knowledge of how your home in Wandsworth can deliver all of the requirements of modern living.

KITCHEN REMODELLING & RENOVATIONS WANDSWORTH
The advantage of restructuring your property, or of building a house from scratch, is that you have full control over the size and lay-out of your home. But the things to remember are that a large rectangular kitchen diner will benefit from being divided into zones, and that, if the space is ‘L’-shaped, you have the opportunity to keep the food preparation area out of sight from the dining area.
Positioning your kitchen diner so that it backs onto your garden can encourage you to dine in the open air when the weather permits, and provide you with a nice view of the garden at other times of the year.
This connection with the outside can be enhanced through the use of sliding or bifold doors, or with the installation of French doors if they would be appropriate for the style of your property.
Of course, the choice of a more ‘outdoor’ lifestyle can be further encouraged by the creation of a pleasant outdoor eating area within easy kitchen renovation.
HIGH-END RESIDENTIAL BUILDERS WANDSWORTH
