Granny Annexe Price Guide
We believe that transparency is key when it comes to budgeting for your garden annexe project. That's why we have put together a comprehensive price guide to give you an idea of what you can expect to pay for some of our most popular garden annexe sizes.
Our prices are based on the external dimensions of the structure and include everything you need to get your new living space up and running, including ground screw foundations, electrical connection, plastering, painting, installation, and BS3632 Certification. This allows you to compare prices easily and make informed decisions about your project budget. With The Granny Annexe Company you can have peace of mind knowing that the price you see is the price you pay. There are no hidden fees or unexpected costs. Let us help you bring your dream home to life.
As every annexe we build is completely bespoke, we have included a selection of real project examples below to help you understand what can be achieved at different price points. These examples will also provide inspiration and help you make informed decisions regarding the size, layout and specification of your own annexe.
