A corner summerhouse can turn an overlooked end of the garden towards the best view. Its angled front also makes the room feel open. The trade-off is a less obvious footprint and shorter internal wall runs.
Draw the real shape
Do not test a corner model as a simple square. Mark every wall, the roof overhang and both open doors. Then place the largest furniture against the remaining straight walls.
Inspect the hidden sides
The back walls still need treatment, ventilation and rain clearance. A shape that slots tightly between two fences may be impossible to maintain.
Use the garden fit checker for the first envelope, then replace its rectangle with the maker's dimensioned footprint.
