    Hi I'm at the stage of my 1st floor side extension were I need to breakthrough from existing house. 20171123_195128.jpg basically up the stairs to the right where the window is now is where the corridor is for extension to bedroom and walk in wardrobe. Have to put a 3 step riser staircase in to level. 20171123_195050.jpg need some advice on putting the lintel in on the extension side. 20171123_195720.jpg left hand window is the landing on stairs where I need to breakthrough and right hand window is in the shower cubicle in bathroom which is getting bricked up. 20171123_195853.jpg what would be your guys plan of attack. Props and strongboy. What size lintel ect.

    I did something similar. I didn't need any props because the wall plate was so close. I fitted the lintel first, a 140mm concrete one, then removed the bricks below and fitted some extra wall ties.

    I would fix some strong galv brackets to the sides of those trusses and onto the wall plate then prop with a stout plank and a couple of Dan Ackroids. I'd remove the window and the proposed door masonry and then re-build with the new lintel.

    And I'd do it all whilst the missus was in the shower.

    Good idea...2 acros onto trusses with long sturdy timber l. Remove both windows and wooden lintels. Put in concrete or steel lintel? Directly under wall plate. To length of both windows...150mm either side. Need Padstones? ???

    Steel. It will behave better under point load.

    Probably yes.

    Yes/no.

    Why such a long lintel if the shower room window is being bricked up?

    Because the wooden lintels were off set I wouldn' of got the 150mm bearing either end so thought best to take them both out and prop. Also the internal leaf on bathroom window isn' being blocked up just the outer. The mrs wants me to frame some tiled shelfs in there. That make sense?
