Buying and building a garden room
The short answer
Decide what the room is for and how big it needs to be, check it fits the planning rules, then get two or three quotes you can compare like for like. Pay in stages tied to the work, never everything up front. A room you can use all year needs proper insulation, a solid base, certified electrics and good ventilation, whoever builds it.

Common questions
How long does it take to get a garden room?
Allow a couple of months from first quote to using the room, more in busy seasons. Once your slot comes up, a prefabricated room can be installed in a day to two weeks, and a room built on site typically takes 2 to 4 weeks.
What makes a garden room usable all year?
Proper insulation in the walls, floor and roof, a solid base, certified electrics, heating sized for the room and enough ventilation to avoid condensation.
