A question often asked by new customers is ‘how large’ are the annexes we build in people’s gardens.
You might be pleasantly surprised to know that our granny annexes are probably larger than you think and represent excellent value compared to a similar sized bungalow.
The question of ‘how large can I have my annexe?’ is only limited by the size of your garden and possible building regulations particular to your area.
