Choosing the right size summerhouse or garden room is one of the most important decisions you will make before buying. The correct size will depend on how you plan to use the building, the space available in your garden, and any planning or boundary considerations.
Start with how you will use the space
Think about what the building will primarily be used for:
A seating or relaxation area
A home office or workspace
A hobby or craft room
A multi-purpose garden room
A building used for furniture, desks or equipment will need more internal space than one used occasionally for seating.
Consider internal and external dimensions
Product sizes are usually listed using external measurements, but internal space will be slightly smaller due to wall thickness. If space inside is critical, always allow extra room so the building does not feel cramped once furnished.
Allow for doors, windows and access
Make sure there is enough clearance for:
Doors to fully open
Furniture to be moved in and out
Safe access around the building for maintenance
Door and window placement can also affect where the building can be positioned in your garden.
Think about the future
If your needs may change, choosing a slightly larger size can help future-proof the building and avoid the need to upgrade later.
You may also wish to review planning considerations and base requirements when deciding on size.
