Single storey back extension, full width.
Purpose: dinning room.
Adjoining rooms: kitchen and living room.
4m projection, 8m width (roughly).
Both side walls are leaning to garages (mine and neighbour's).
(Apologies for changing this significantly during the process, but some things changed on our side)
Add dinning / living room to the current space.
Redesign adjoining rooms if needed.
Like: orangery type of extension (low wall, a lot of windows / doors, roof windows etc.). Need to be used throughout the year and have radiators (so solid insulated roof with velux windows or similar).
Note; I am not sure if I am providing enough info, so please come back to me with questions and i will enrich the description
