Bridge Garden Rooms have created one of the largest ranges of granny annexe designs. From compact homes to large multi room designs.
Interestingly, they also offer self-contained annexe designs which can be attached to the house.
If you have a plot of land and are looking to make money. Why not add one or more holiday pod buildings. There are lots of different designs on the market that can quickly start paying for themselves.
Building With Frames has recently completed a series of holiday pods in Cornwall. Each pod was completed off-site to Building Regulation standards, transported to the site and craned into position. This process can be completed in a matter of hours and once connected to the mains supplies, the pods will be ready to let.
