Design + Build at the heart of Four Squares’ philosophy, we have progressively evolved  and developed our range of capabilities. Since the year 2017, we reformed to create a new brand identity which reflected from our clients specifications. Our core architectural design and build service is supplemented with interior design and bespoke joinery presented by our sister company Four Square Interiors. Rest assured your design won’t be left to the contractor to figure out how to cost and build it as we are the contractor. We will tailor each individual scheme to your personality, taste and design flair. The spaces we create don’t simply look immaculate but we design them too feel immaculate. More than just mechanical building, we combine our building and project management capability with our excellent offering a complete service client – liaison skills, offering a complete service. We can can also work to pre-designed plans and drawings, either directly for individual homeowners or as main contractor for a boutique selection of award-winning architects and interior designers.  Every loft conversion is unique, we put a huge amount of energy into understanding precisely what you’re trying to achieve, the thinking behind it, the look, the specification, right down to the last detail. Let our dedicated team of experts and craftsmen on hand to make sure everything runs smoothly, professionally and on time.

FOUR SQUARE DESIGN & BUILD is a great company to do business with! They are prompt and timely with their service when it comes to scheduling. As far as workmanship they just cannot be beat and I would recommend them over any other construction or refurbishment company in Fulham area I’ve used FOUR SQUARE DESIGN & BUILD for major refurbishment to my property. The Company ‘s Project Manager, walked me through the process, took over dealing with the building control and other regulatory bodies , keeping me in loop every step of the way. I’ve had my house remodelled and they offered me a very reasonable quote, the end result, exceeded my expectations and were Very professional. They did such a great job and were quick and efficient. The crew was attentive reliable and dependable and courteous We would definitely recommend to anyone looking to have their home refurbished. We couldn’t be more pleased with his service! They showed up on time, worked hard, cleaned up, easy to communicate with and completed the projects quickly and as scheduled. Always willing to answer my questions from start to finish or make a recommendation before the started. Really appreciated the honesty I highly recommend FOUR SQUARE DESIGN & BUILD for general refurbishment / construction needs. Any homeowner choosing to work with them will be very pleased and extremely satisfied.

After a long and hard search to find a trusted company to do our rear extension, loft conversion and full renovation , we have found four square. Excellent and a professional team, all the work was planned and communicated to us. Gave us honest advice for best results, we felt in control throughout. Delivered the job earlier than scheduled with such great quality and transparency. I would not think twice about using them again and recommending them to friends and family.
