    Hi , looking for advice please.
    We intend to open out this door and small window area to create a larger door opening by replacing the concrete lintels with a steal beam - RSJ to hold the joists on the inner leaf and a concrete lintel on the outer leaf. The outer wall has only 3 courses of brick above it where it enters the loft. The inner wall holds 3 floor joists and 3 courses of brick where it also enters the loft.
    I'm not sure what size RSJ and concrete lintel to use to cover the new 60 inch opening ?
    Is it acceptable to rest the RSJ onto the breeze block ( 1970's )inner wall or is a "pad stone " required?
    Thanks in advance

    152 x 89 steel beam; with 200mm bearing each side on stiff mortar, very unlikely to need a padstone if the loads are as you say.

    Your building inspector (if there is one) will, however, see it differently and will demand a padstone, though will not be able to say why :LOL:

    Thanks for your reply. I have no objection in fitting padstones, and guess they bridge the cavity sitting on both inner and outer walls?

    Use a single engineering brick as a pad stone if you must have one.
