A mortgage that's as unique as the home you build

There are currently no Self-Build mortgage products available

If you're looking to build, renovate or convert your own home, Newcastle Building Society could provide you with the funds you need. Our self-build mortgage is simple and straightforward and helps you construct your home the way you want.

You might be looking to borrow the final value of the property or the total costs of the project, either way, we will consider your mortgage application. When working out your budget, we normally suggest you build a contingency fund into your costings. This is because any building project can be susceptible to a few hiccups along the way, but with a contingency, there's no need to worry.
