Converting and renovating an existing extension
We have a rear extension approximately 7.5m x 7.5m, there are currently 3 bedrooms and a large bathroom in this space (floor plan below). The walls don't seem to be cavity walls, the roof is a butterfly felt roof (picture below). The floor level of this extension is lower than the rest of the house due to a sloped plot we are on.
We're looking to remove the roof and ceilings, knock through all the internal walls, remove the external wall on the west side and replace it with a full glazed wall (+doors). The idea is to convert this space into a kitchen / diner / family space.
Can anyone advice on what sort of ballpark cost we might be looking at per square meter, excluding the kitchen fit because obviously that can be a huge range. We're looking for the cost of:
- Gut all out as described above (could do this part myself if it made sense)
- Install a flat roof (fibre or single ply rubber)
- Insulate the external walls on the outside and render
- Insulate the base/floor and install wet under floor heating
- Slim framed glazings
- Electric wiring and plastering the walls
The space should be ready after this install the new kitchen and fittings and fixtures.
Any help and guidance will be appreciated.
