    Lintel in footing close to knock through

    If that's the case, its not going to be a problem. The load distributes downwards as an ever-widening triangle due to the bonding of the brickwork and by the time it gets to the level of the pipe, it will be so 'spread out' as to be minimal.

    Lintel in footing close to knock through

    is this what you mean, or is the drain to the right of the bearing, rather than on the left as I've shown it?

    Found notched roof timbers, should I repair it?

    That depth of notching won't be an issue, particularly with them being near a vertical support.

    Mortar failing in 2 year old garden wall

    If there's already plasticiser in Mastercrete, could it be that you've added too much additional plasticiser, which weakens the mortar? If so, you seem to have included a yellow/ochre additive?

    Mortar failing in 2 year old garden wall

    To me, it looks as though the mortar has dried out too quickly, even though you wet the bricks first; they may have been particularly thirsty. Did you add any plasticiser? This helps retain water within the mortar so that it does not get absorbed by the brick too quickly. It also makes the...

    Wall stability without a return

    You need to get the 2100 long wall checked as a panel wall, bonded at one end, and simply-supported top and bottom, with one free edge. If it was shown not to work, a coated steel post within the cavity might be necessary, with a plate bolted to the concrete foundation, and fixed to a wall...

    Wall stability without a return

    If it has a roof it will provide a degree of stability, but might a narrow brick pier work lose over time with a wide, heavy door banging shut? Your diagram isn't very clear, some dimensions would help.

    Pitched Roof renewal - how to satisfy BRegs?

    They are mistaken. Current guidance is to top up the ceiling insulation to 250mm glass wool if the insulation is not already to that standard.

    Planning application for roof works

    If you are replacing the roof covering of a pitched roof (even if using same tiles), Part L1b comes into play. This states that, at the same time, any loft insulation should be topped up to 250mm, if not already that thickness. This requirement appears in my old 2010 copy of L1b, and is the...

    Lots of cracks appearing internally

    Looks like normal plaster-shrinkage cracks.

    Garden room roof support

    I know you've now (sensibly) discounted I-joists, but how would they have been more 'energy efficient'?

    What fixings on these hollow bricks?

    Extruded clay blocks - hard and brittle. Is it possible to cut 50mm wide vertical chases in the plasterwork (marking the lines with an angle grinder) at - say - 500 spacings so that you can see the mortar joints, and then screw vertical 50 x 50 battens to the joints. Then fix your resilient...

    Neighbour cracks in walls

    If its a normal one-brick (225mm) party wall, drilling for plugs would not cause that pattern of cracking - as above, more likely to be shrinkage of her plasterwork.

    How much weight can my loft bear?

    There was some research done by Arups some time ago, which found that even in offices, floors were not often loaded up to the domestic loading of 1.5kN/m2. I suspect there is a case for the regs to be changed to accept slightly lower loadings in loft conversions (say 1.0 - 1.25 overall) on the...

    Planning Application not even Assigned and Officer after 3 months

    I'll bet they banked your application fee pretty quickly, though.

    7.3 N/mm2

    Concrete blocks of that strength would be expensive, very heavy for the bricklayer to lift, and not necessary for the relatively small loads in domestic buildings.

    7.3 N/mm2

    The 20N and 30N figures you quote for bricks seems at first glance much stronger than the 7.3N block. There are far more mortar joints in a square m of brickwork than in a square m of concrete blockwork. The mortar, being often of variable quality, is a source of weakness, so the design codes...

    Whats the name of this brick work?

    As Charlie said, plain old common-or-garden strecher bond.

    Floor joists for garage conversion

    Why not use thicker PIR if you've got the depth?
