We're having an extension done by a builder we don't 100% trust and want to feel sure the front of the house isn't going to collapse - that he's done his RSJ calculation.
We have a mid terrace two storey property that we have a builder doing a front extension on. The extension is 6.5m wide and comes out 2.5m.
The extension extends the lounge, the entrance hall and adds a downstairs cloakroom.
We are due to have a RSJ fitted across the front wall of the house at ground floor ceiling height. It will have to support the front (upstairs) of the house (a cavity wall).
The lounge span is 3m. The hall in the middle is 2m and the cloakroom 1.5m (so 6.5m total). There are already some lintels (for the front door) and side door (where the cloakroom is going).
It was originally supposed to be done as 2 lintels (one across lounge and entrance 5m) and a small 1.5m one over the cloakroom.
The builder now wants to split the longest one in 2 so making it easier to handle as he says it's about 70kg/metre - but the wall in the middle (between lounge and entrance) is only a 1/2 brick wide (10cm). This was only originally going to be supporting the middle of the RSJ. Does this sound ok with people on here? There's enough room for a padstone at each end of the 6.5m span (at least a foot of space) - I'm just concerned about the load on the middle pier.
