Self-build mortgages 

Mortgages designed to help you build the home of your dreams.

Do you dream of buying a plot of land and building your own home?

If the answer is yes, Newbury Building Society may be able to help you. Self-building enables you to choose exactly what sort of property you want and build it to your specifications. Around 10% of new homes in the UK are self-built.

To get a mortgage for a self-build project, speak to us to discuss your options. We’ll need to check the plans in detail before making a lending decision and because it’s likely that your project will take some time, we can arrange to release your funds in stages in line with the progress of the build.

Extremely helpful, prompt and willing. Newbury helped us with a self build mortgage when most others did not. They have been brilliant throughout, reasonable with their fees, helpful and prompt when we need to draw down our stage funds. We highly recommend them.
