Cost Effective Home Extensions in London with Simply Extend

Home extensions or kitchen extensions are relatively cost effective and extremely versatile. In the current financial climate, with London house prices continuing to increase, many families are simply priced out of the market for a new property. Fortunately, a home extension, whether this is a kitchen, wrap around extension, flat roof extension, rear extension or side return extension in London can provide you with the additional room they need at your existing property. House extensions can build an improved home without breaking the bank, so get in contact with Simply Extend, the leaders of home extension builds in London today.

Of course, while home or kitchen extensions are cost effective in comparison to home purchases, they still require a lot of effort and a fair amount of time from the initial site survey to the décor in the finished space. That’s why Simply Extend extension builders pride ourselves on providing the simplest, clearest, most comprehensive home improvement and domestic extension building service available in London.

    What our clients say about us

    Kitchen extension | Skylight | Kitchen island | Simply extend | Dark Cabinets

    We engaged with Simply to build our kitchen extension recently and are really pleased with the results. Simply managed the tender process and appointed a Project Manager and construction team. The price was very competitive and the process made very easy. The Project Manager and the build team were excellent, very responsive, on time, hard-working and clean. They were great at providing options and advice to challenging design issues and were always happy to change things along the way for no extra charge. The team have also been very responsive with sorting out the snags. We are very happy with the results and would recommend the team.

    Kitchen Extension – South London

    We’ve held back on writing our review for some time – there seemed little point in posting our thoughts until we’d had time to see how the workmanship stood up to a few years’ wear and tear… and we can now safely report that the results are fantastic. No sagging, cracks or water ingress, and still looking great some three-and-a-bit years on.
    During the build itself the team were punctual, polite and listened to any concerns that we might have. The final part of the build did go on a little longer than we hoped, but speaking to others who have had similar work done it seems that’s more an industry standard than a problem with the build.
    In terms of after-care, we’d like to give a big shout out to Lorraine who followed up with us to make sure we were fully finished and happy with the results.
    All in all very happy with the work from Simply. So much so that we may well be using them for our next project.

    Rear Extension - South East London

    I used Simply Extend for my side return extension on a terraced house. The team were on time and professional and provided some great design solutions I would not have thought of (e.g. placing the boiler above the bathroom door instead of the kitchen to save space). My project manager was on hand to communicate updates and respond to queries and issues arising were dealt with in a timely and efficient way. The project ran to budget with the cost of my requested variations clearly communicated and competitively priced. I am really happy with the quality of the build and design which other tradesmen have also admired.

    Home Extension – North London

    Having considered a rear extension for a couple of years, the pandemic made us realise we needed more space. Simply Extend provided a very detailed quote with clarity on what was included and excluded in the cost. They provided contact details of work carried out by them in our area and after viewing a similar extension to what we wanted we decided to go with Simply Extend. The Simply Extend dashboard is great for keeping track of payments and managing variations for the project. Fantastic customer service provided by Holly and Lorraine, who were both really helpful in addressing any issues or concerns we had.
