Kitchen Extensions

Creating a large, open-plan kitchen can modernise your home while creating a fantastic space for family evenings and social events. As part of your kitchen extension, we will remove interior walls, create additional structural supports, and completely refurbish the interior.

Glazed Extensions

Natural light is incredibly important in the home – particularly in such a high-traffic room. Glazed extensions can unite the kitchen and garden while creating an airy, light room. We can create traditional and contemporary glazed extensions, depending on your interior design and general preferences.

Bi-Fold Doors

Bi-fold doors are a real centre piece in kitchen extensions; they allow an uninterrupted view of the outdoors and let you open up the kitchen completely. Whether you want to feel the breeze in summer or open up our ground floor when entertaining, adding bi-fold doors to your extension will certainly achieve the effect that you want.

Extension Sizes

While most clients agree that bigger is better, there are a number of restrictions on the size of your kitchen extension. The most obvious is the size of your garden; you will need to decide how much of your garden you will be willing to use for the extension. As part of this process, many clients opt to landscape the garden and add more decking/patio space as the kitchen extension often builds onto the existing pavement.

If you are building your kitchen extension as a permitted development, there are further limitations placed on size. These extensions can’t be more than 50% of the size of the original property (for side extensions), and cannot be more than 4m in depth. The extension must also be lower than the existing roof, and should be made with similar materials to the rest of your home.

Planning Permission

If you live in a conservation area or you’re not happy working within the restrictions placed on permitted developments, you will need to apply for planning permission to build your kitchen extension. This will require full architectural drawings of the layout and any elevations. We work with a number of architectural partners who will provide the drawings, design, and gain planning permission on your behalf.

Planning applications usually take approximately 8 weeks to process.

Our Process

During our initial meeting, we will discuss your requirements and the potential costs involved – we cannot provide definite costs at this stage since the designs have not been created so the parameters for the work are not clear. We will put you in touch with our architects (if you prefer) who will create your design and go through the planning consent process for you.

Once we have the working drawings, we will finalize our quotation and draw up the paperwork for the build. At this point, you can change your building materials or discuss the design further with the architect.  However, this is more difficult once planning permission has been granted or if we have already purchased the materials. Therefore, we ask that you sign off on the design when you sign the paperwork with us. The paperwork will include a specification of work and a payment schedule.

When the paperwork has been signed, we will agree a start date with you and schedule a pre-start meeting so you can meet the site foreman and answer any final questions you may have.

Since the kitchen is so integral to the running of your household, we offer to set up a small, temporary kitchen elsewhere in the house while we complete the work. There are a number of options for grills and tea making facilities to minimise disruptions while we build your new kitchen.

Kitchen extensions typically take 8-10 weeks, depending on the size, design, and interior. The site foreman is responsible for keeping your work on schedule, and he will discuss any delays or issues with you as they occur.

Satisfaction Guaranteed

We have a 100% satisfaction guarantee, and will not consider a job finished until you are absolutely happy with it. Over 90% of our work comes from personal referrals, and we are proud of our excellent customer service as well as the beautiful kitchens we build.
