Choose an Isleworth Kitchen Extension Specialist

Whether it is the riverside beauty or London city lights that make you want to stay put in Isleworth, we know you want your home to be the ultimate comfort zone to appreciate your town’s worth. A home needs enough space for all its occupants to share the joy of living together. We love to bring you that joy with innovative solutions that open up new spaces in your property without having to move. Kitchen extensions Isleworth do the seemingly impossible by providing much-needed space for your home. In a time when bigger kitchens are just as much as indispensable as sitting rooms to entertain and hang out as a family, your interest in a newer and better kitchen is well in keeping with the times. Let’s make that happen for you with minimal worry.

Don't move. Extend in style

We can save you the hassle that comes with moving not to mention the heavy stamp duty! Adding an extra loft bedroom or enlarging the living kitchen dining space on ground floor is an economical way of transforming your home to suit growing needs. The projects can range from £40-100K depending on your requirements and can be completed within 8-16 weeks.

Single Storey Side Return – for semi-detached and terraced urban properties, this is a classic. It builds out on to the pathway beside your house along a boundary wall. If you don’t want to compromise back garden space and want the most cost-effective method, this is it.

Single Storey Rear – If you don’t have the option for a Side Return or need much bigger space, a rear extension does the trick. It extends towards the back garden and covers the whole width from one garden wall to the other.

Double-Storey Extension – side and rear double-storey extensions can save more garden space and add twice as much space as a single-storey extension cost-effectively. With the same foundation and roof, you get additional space.

Wraparound – the addition of both a Side Return and a Rear extension jointly in L-shape can create a wraparound for a spacious extension.

A house extension is a Permitted Development project; however, limitations apply. These are;

  • Your property is not on designated land
  • Only half of the land area should cover with extensions
  • Extensions cannot exceed the height of the highest part of the roof
  • When extensions come within 2m of house boundary, height at the eaves cannot be more than 3m
  • Extensions must not include raised platforms, verandas, or balconies
  • Any alterations to the roof of the original house must not take place

You will also need Party Wall Agreements from your neighbours for building to take place.

We are home remodelling professionals with over 12 years of experience and expertise in period properties in London. Our team consists of the industry’s top architects, structural engineers, and skilled builders who put your needs first. You get a comprehensive overview of the total cost before the project kicks off. We offer full transparency of the spending, and our diligent project management ensures you remain well-informed until the very end of the process. Our flexibility allows for minor changes, even at the completion stage.

After the free initial consultation we provide, you also receive a free site visit and itemised quote. If you are willing to go ahead with us, the crucial Design stage begins. To create precision CAD designs, we carry out a complete architectural measured survey of your property. After familiarising ourselves with the available space, we will draw up bespoke designs inspired by your ideas, requirements, and choices. If your extension in Isleworth needs planning permission, we start the application process sparing you the hassle of it. At the technical stage, we prepare technical drawings and structural calculations and offer you a ‘no obligation’ quote for the Build phase. If you are happy with it all, we sign the Build contract and start construction work.

Angles – right sloping of the roof and glazed walls can bring in more light, better aesthetics, and maximise available space.

Minimalist – clean edges, smoother surfaces, slimmer proportions, and light colours are all space-saving and space-enhancing design features.

Movable skylights – electrically operated skylights you can open give a more outdoorsy feel to the extension. Oversized sliding doors, too, can enhance the appearance of the space.

Seamless Integration – by choosing similar colours and material, you are working in harmony with the rest of the house, so it doesn’t look like an extension at first glance.

A kitchen extension for your Isleworth house starts from £35,000. The size of the extension, the style, design features, and material you choose are the major deciding factors of the cost.

How we deliver projects

Our process is simple and divided into two distinct phases with separate contracts: Design and Build. As a client you only commit to one phase at a time depending on what stage of the process you are in. Each phase consists of three stages as described below.

1. Design

This is the kick-off point for your project. We carry out a complete architectural measured survey of the property. This allows us to create accurate CAD design drawings. This is followed by a design meeting to start discussing your ideas in more detail.

2. Planning

At this stage we finalise the designs with you and start preparing planning applications as needed. We place a high priority on ensuring that plans, designs and schedules are all based on a thorough and detailed understanding of planning guidelines. We co-ordinate with local authorities until the decision is made, and the planning approval is secured.

3. Technical

Once the planning consent is secured, we translate the design drawings into more detailed technical drawings for the purposes of building control and construction. This also includes specifications and structural calculations. At this stage, we will also submit to you our ‘no obligation’ quote for the build phase.

4. Pre-build

90% of our clients decide to stick with us after the design phase is completed. Once the build contract is signed, we kick off the process by making sure all the pre-build processes are complete. These include assistance with party wall agreements, Thames Water build over agreement, submitting building control application, and preparing method statements etc as needed. This stage ends with a pre-start meeting with your foreman before the actual build begins.

5. Build

One of our foremen will be dedicated to your project and will be on-site to manage everyday works. Our project managers will be overseeing the works to make sure they are completed to high standards, within your budget and on time. Throughout the process we will keep you updated with the progress and coordinate the works with third parties such as kitchen or flooring suppliers. We will also advise and guide you to choose any suppliers if needed.

6. Handover

As the build draws to finish, we will help to iron out any ‘snags’ to make sure everything is completed to your satisfaction. We will put together all necessary certificates such as gas, electricity and building control completion along with warranties for glazing, boiler etc. At the final completion meeting, we will hand you these documents, together with the keys to your house. Needless to say, you can contact us any time after this, if you want us to look at something.
