Welcome to SimplySelf-Build...

Simply Self-Build is recognised as the UK's leading timber frame package company. Our expertise and environmentally-friendly way of building make us first choice for unique self-build homes, extensions and house conversions.

What type of project are you planning?...

Simply Self-Build is the UK’s leading self-build housing company. And, because we specialise in complex and advanced ‘green’ projects, we also offer a variety of ways to extend or convert your existing home using the UK's most advanced building technique: engineered timber frame.


The experienced gained from building thousands of homes around the UK and abroad helps us to really understand the motivations, complexities and needs of a self-builder during this exciting venture. We understand that your self-build project is unique, and that a ‘catalogue home’ simply won’t do for you.


As such, we offer a completely tailored solution to getting your project started, offering only the finest, precision-made timber frame and environmental solutions for your design.


Our promise to you is:

  • We will take the time to understand your project and needs to allow us to offer your best value
  • We will offer specialist complimentary services to offer you the best support and help you get your project completed on time, and on budget.
  • We will always be up-to-date with industry issues, including building regulations, planning guidance, innovative solutions and green products.
  • We will offer highly-engineered, environmentally-sound building solutions from the finest environmentally-certified manufacturers.
  • If we erect your home structure, we will offer a 60-Year Structural Warranty.
  • You will be supported by a dedicated specialist team of highly-qualified and experienced professionals.

Self-Build Home Solutions

If you decide to self build you won't be alone! Up to 20,000 people build their own homes each year and many others will carry out an extension, renovation project or conversion. The market is estimated to provide about 13% of all the new houses that are built throughout the country, making self-builders the UK's largest housebuilder.

The most important function of the 'self builder' is to oversee and manage the project from start to finish, as opposed to building a new home on your own with their 'bare hands', as is commonly thought.

In many cases project management is being handed over to specialists in this field such as Simply Self-Build who offer specialist project management services, leaving the self builder with a more 'client' role, as opposed to a more stressful and hands-on 'project management' role!


Home Extensions UK Solutions

Believe it or not, timber frame home extension projects require the same level of specialist knowledge, skill and support as a self-build home build project. Whereas with a new self-build home we essentially work from a ‘blank canvas’, but with an extension project, we must consider existing structural elements, loadings, building methods as well as precision engineering.

This is why we are the UK’s #1 supplier of timber frame home extension kits in the UK, and is why we are able to help anyone, with anything.

From new hexagonal turrets and multi-floor extension projects, SimplySelf-Build can handle them all…nationwide.

Property Development & Conversion Solutions

Similarly with home extension projects for timber frame, conversions and bespoke renovation projects can be very complex, and - we have found - that we can offer some very innovative and novel solutions to conversion and development issues.


Whatever step of the Self Build journey you are at: thinking, designing, planning or building; and whatever type of self-build project you are planning; new home, extension, conversion, renovation...we can help.


We look forward to talking to you.
