Lean-to conservatories, especially those with UPVC frames and a poly-carbonate roof can easily be considered the best option when it comes to value for money and for the ability to fit into small spaces nicely.
Softwood doors with a hardwood veneer can be some of the cheapest, with UPVC being a close second. Aluminium and composites will cost more. UPVC is a good choice because it’s relatively inexpensive, a good insulator and lasts a long time.
Through careful forethought, planning and soil preparation you can construct an awesome garden room space, a true extension to your home’s internal living area, and add considerable value to your home at the same time.
