Cheapest way to add an extra room

[SpringGreensPreens]

Could you help me brainstorm? I need an extra downstairs room, what’s the cheapest way to achieve this? Can’t be fully glazed as would get too hot

Are you considering reconfiguring your existing downstairs, or adding an additional room as an extension?

You can buy modular add on rooms

Can you get a garden summer house type room?

Dividing wall inside a current room?

Someone else has said it, a large summer house, but log cabin style so it’s cost in winter too

Cosy

Divide an existing one would be the cheapest!

Your home made perfect on the BBC last night added a liwcist/prefab modular home. They kitted it out as a large utility. Looked great.

Low cost!

If you've got a through lounge, put the original dividing wall back up.
