Can you use an old garage base as the foundations or support for a garden office? The simple answer is yes, as long as the base is in good condition, has been laid properly and is strong enough to support the building that you want to put on top of it.
An example of this is a garden building in Somerset designed by architect Gordon Smith. His clients and transformed two dilapidated holiday flats into a stunning holiday home. They now wanted a home office and occasional guest room. The only spare space they had for this was on the base of an ancient timber garage. And the ancient timber garage was in a very interesting position approximately eight feet above the level of the garden.
And it was a very small garage. About the right size for a Morris Minor, but was the base going to be big enough for an office and guest room with an en-suite shower room?
Well yes, with a bit of thought and creativity. If this micro building was built to the same foot print as the garage base there wouldn’t be enough room to walk round the end of the sofa bed when it was opened out.
So, Gordon designed a small bay window into the tiny building to allow room to walk round the end of the sofa bed and to give a really good view of the surrounding country side and the Severn estuary.
Of course not all garage bases are as robust as this, so it is important to get your garden building manufacturer to check your garage base and reassure you that it is up to the job. If your garden office needs to meet building regulations you would need calculations from a structural engineer to prove that the base was strong enough.
And the final result: A beautiful garden building, clad in waney edge larch.
