"We were on the search for a building company to manage and execute a project to build a single story ground floor kitchen extension and breakfast room, build a L shape loft conversion, fit 2 bathrooms and 1 kitchen. Michael and the team were able improve on the build, these items were delivered off plan: Michael worked with building control to keep our ground floor open plan, maximising our living space by installing a state of the art & hidden Automist solution. He also recommended we increase the size of a skylight in our second floor stairwell to 2m, which added a touch of quality to the finish.

Michael came up with a solution using a turret system to create a patio level with our indoor floor, which when coupled with the bifold doors he had custom built, has become one of the best features in our house.

Working with Michael was a pleasure, he was always on hand for a call, in constant communication and always supplied photos of the work completed and a written summary via WhatsApp at the end of each day. Many of my neighbours and building spoke of how Michael and the team conducted the quality work in a kind and considerate manner.

Overall, Michael has delivered us a family home that we are exceptionally proud of and will be very happy in for years to comes. I can highly recommend Michael’s services to anyone who is on the hunt for a top building company that delivers exceptional value for money.

Architecture & Planning

We will help you through every stage of the design process of your kitchen extensions from inception to build. At the initial consultation we will all conduct a full survey of the property. Existing and proposed plans will be provided in good time. The structural drawings are produced promptly as well. Everything is done to efficiently take your project efficiently to the build stage. These photos here are of a curent side extension that really has changed this lovely property in Chiswick. As for the full project files to see the full process.


We specialise in kitchen extensions particularly and providing this service at the best price and quality. We undertake all types of kitchen extensions. If you are considering a loft conversion as well we recommend that they are done at the same time as there can be considerable areas of overlap when managed correctly. All teams start 8:00am and work till at least 5:00pm, with half hour for lunch (and two short breaks either side). We will get you project done to a high standard quickly. Get in touch to start your project with an initial consultation. 

Project Management

I own the business and visit all the sites myself. With the assistance of another project manger each site is never more than 24 hours without a stakeholder attending the sites. We manage no more than four projects at a time and there is no doubt that you will receive a personalised service. As well as daily updates on you project, you can also leverage our networks of suppliers for your internal choices. We provide a few different construction services, however our expertise is in kitchen extensions.

Our team particularly excel in larger complicated refurbishments.

Single storey extensions are finished timely and to high standards.

Client focused, our aim is to provide considerate expertease.

I am always amazed how much difference taking down some walls and extending a kitchen completely changes a house!

I particularly enjoy the side extension process as creating one big open space at the rear of the property really benefits families. Not done one yet where there has not also been room for comfortable seating and a TV on the wall.
