What is Self-build and Custom-build?
A Self-build is where someone directly organises the design and construction of their new home. This covers quite a wide range of projects. The most obvious example is a traditional 'DIY self-build' home, where the self-builder selects the design they want and then does much of the actual construction work themselves. Self-build also includes projects where the self-builder arranges for an architect/contractor to build their home for them.
Custom build homes tend to be those where you work with a specialist developer to help deliver your own home. This can be a more appealing approach as you'll have an 'expert' guiding you. These companies can provide you with everything from securing or providing a site in the first place, through to managing the construction work and even arranging the finance for you.
