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.










Making the right choice of a builder is very important, because spending money on a project and then not being happy with the outcome can be both expensive and heart-breaking. That is why it is not a good idea to just pluck the name of a builders in Chiswick area, and a number of other tradesmen, from a directory.

If it’s time for a bathroom renovation, it’s best to call in the experts. Renovating your bathroom is almost always an excellent investment, adding luxury to your bathing experience and value to your home. However, undertaking a project such as a bathroom renovation by yourself can be tricky, it can take a long time and costs can spiral out of control.

There is a growing trend to incorporate modern designs into bathrooms, and we can help you achieve this kind of design, as well as the more traditional styles. Whether you are looking to add an ensuite bathroom, create a wet room or just simply give your bathroom a fresher look with more space, we will be able to make it happen.

The desire to bring all of our disciplines in-house was born out of a vision to help our clients create truly exceptional homes. Not unlike the finest restaurants in the world that control every element of preparation from field to fork. Sourcing the most delectable and rare ingredients and combining this with hugely dedicated and experienced teams, to produce unforgettable gastronomic experiences. These are precisely the service levels that our clients receive and have come to expect whilst working with us.


Before entrusting any tradesman to undertake work in our company’s name, we go to great lengths to make sure that he or she can meet our very high standards. This includes a requirement to produce documentary evidence of certificates and accreditations.

We insist on every member of our team having at least 24 months’ experience, and that they are fully paid-up members of a relevant trade association. This is why you can have complete faith in our ability to deliver a good service.

We take seriously the fact that every member of our team is a company representative, and this enables us to maintain such high levels of workmanship and customer satisfaction.


We have a Quality Assurance system whereby our clients rate each one of our employees on a scale consisting of 1 to 5 stars. We do this for a total of 6 performance indicators, which include workmanship, value for money and cleanliness. We also ask our clients for a written testimonial on the good points, as well as any points for improvement, arising from our service.

In the unlikely event that a client is not completely happy with any aspect of our work, we have a procedure in place to review the issue so that the matter can be resolved to the satisfaction of both parties.

If the conclusion from this process is that a member of our team has been found wanting in any way, then that person will cease to be involved in delivering a service on our behalf. This is how we ensure that our clients can have complete confidence in us as a company.


To provide our customers with complete peace of mind, we maintain all of the necessary public liability and building trade insurance covers. This added protection comes at no additional cost to you, so why not contact us today for a free, no-obligation quotation?


Before a building project can commence, it is necessary to obtain any necessary Planning Permission to do so. This mainly subjective process will also determine the detail of what the project will finally look like.

The Building Control process, on the other hand, is more objective in that it relates to specific structural and technical standards contained within the Building Regulations. (In Scotland, it is a ‘Building Warrant’ that is required). Generally, a building either adheres to the regulations or it does not, although Building Inspectors do sometimes have some freedom to use their discretion.


The final act in a build is for a Building Inspector to visit the property and, if all complies with the required regulations, to issue a ‘Completion Certificate’. This is a certificate that must be kept in a safe place, so that it can be produced, on request, along with all planning consent documentation, in the event of any change of ownership. A Completion Certificate might also be required by a lender before a final payment is made, and might also be needed for warranty certification or for reclaiming VAT.

What our clients are saying

Design and Build London have delivered a fantastic service from the beginning to end. I was recommended Design and Build London through a neighbour who was happy with their service. The builders have done a fantastic job with our kitchen extension and full house renovation. The attention to detail from all the tradesman has been exceptional.

Linda Williams, Google Reviews

Design & Build London renovated my house and built an 2 storey extension including moving the bathroom upstairs and creating a kitchen diner downstairs. I can’t recommend them highly enough. Builders and decorators had a great eye for detail, was very responsive, trustworthy and conscientious throughout.

Laura Stevens, Google Reviews

We are really pleased with Design & Build London who recently completed our Kitchen extension to a very high standard. We were very impressed with the end to end service. Work was completed on schedule and efficiently, taking into account a pre arranged 2 week break for Christmas.

Racheal Smith, Houzz

I love decorating but I had so many ideas I didn’t know where to begin and wasn’t confident enough to make choices. My designer helped me clear the clutter, prioritize and now my place looks better than I could have dreamt it up myself
