    Stepped Crack

    If its at both corners on the rear elevation (and not on the front?) could it be thermal expansion if the wall is south facing? The corbels also look to be badly-detailed as they project in large steps, which would have made the brickwork slightly unstable to begin with. If there are any similar...

    Stepped Crack

    A pic from further back, showing the context, would help bigly. It seems to be at roof level (?) and the corbel (stepped bricks) seems to have rotated a little and pulled away slightly. How long has it been there?

    Joint thickness

    Unbelievable; as above, he's no bricklayer.

    Structural engineering advice; open plan kitchen / diner

    That span would have been easily achieved with a 254 x 254 x 73 UC section. A post in the middle would have been a rookie design failure. 0/10. Do we know the outcome?

    Testing foundations with a hammer

    Testing a foundation with a hammer reminds me of those Hollywood films where a man is buying an old car, walks slowly around it, and casually kicks a tyre to see if it is OK. The critical issue in clay is the depth (1.2m seems ok assuming no trees or shrubs too close) and the spread. For a...

    Concrete Coping - Parapet Roof - Am I going mad?

    You worry about that, and then have that tin tube (for the woodburner?) going up the side?

    Placing steels off-centre on a padstone

    As per Mr 888, an L-shaped padstone would have solved the problem, even if one arm needed to be cut down a little.

    removing chimney hearth old terrace house

    They are usually about 2 or 3 inches thick and cast around battens nailed to the sides of the joists. There's no structural objection to moving it, but be careful not to damage the ceiling below. It might continue into the fireplace recess, if so split it with a chisel to prevent damage to the...

    Structural Engineer needed or standard USB size?

    FWIW, my money's on the joists going onto the wall from each side as that seems to be the shortest span. In which case at 1.5m span, the beam will only be carrying some floor load, plus a small component from the ensuite partition. A couple of 150 x 50 C24 timbers screwed together would be...

    Padstones - are we getting them wrong?

    To any SEs here who design padstones for steel beams - you've been doing it all wrong! Forget things such as 'characteristic strength' and 'partial safety factors' - this is how its done. (Home owner and inspector not well pleased o_O).

    Blocking up Window

    Depends on the size of the window. At the least, in the absence of bonding the Fibolite blocks to the existing wall, a steel bracket or two screwed through to the original masonry and bedded into a mortar joint would have been better.

    Cracking idea, or crackers.

    This is the problem with estate agents: buying or selling, you're at their mercy.

    Adding pillar support for RSJ

    The fascia board will cover it. And garages are cold but draughty places. I very much doubt you'd get condensation affecting the end of the beam.

    Building Safety Act Principle Designer - what to do if DIY build?

    As above, the BSA is a bit of a mess. Contractors and designers do not have to be 'registered' under some official body, they only need to be competent to undertake work in their respective fields. 'Competence' is not just limited to passing an exam and having a piece of paper to prove it...

    Adding pillar support for RSJ

    Yes to 1-4, subject to points made previously (exposure, returns etc) Re 5, gravity + friction keeps the beam in position. Of just a little more concern is the height of the block wall above ground level (3.3m). Wind applies not just horizontal compressive force on walls but, more significantly...

    Where can I buy melamine/laminate sheet ?

    It isn't waterproof - are you perhaps thinking of Formica-faced board? A few years ago I was in a DIY store where I heard two 'builders' pulling out some white 225 x 8ft contiboard and one saying to the other, "this will do for the fascia board".

    Do I really, really need a windpost?

    Your first problem is, as Nose pointed out, SEs - particularly inexperienced ones - will opt for the wind-post in order to cover themselves completely, being mindful of their PI insurance. So from their point of view, why should they do some rather more complex wind-load calcs taking time, when...

    Do I really, really need a windpost?

    The old wind-post hobby horse wheeled out again by some SEs. The distance between the party wall and the original side wall of the house seems to be around 5m, which is not excessive for a horizontal span, and IMO no post would be needed, assuming the house is in a sheltered/suburban area and...

    Missing bricks under chimney stack

    Those bricks which are 'edge-on' are part of the foundation to the chimney, so your hole is actually a void you've dug under the foundation. The casualness of it might surprise you, but the ground looks to be sandy and probably of reasonable bearing capacity; the builders of old would have known...

    Adding pillar support for RSJ

    Bolting-down in that situation would serve no useful purpose. As long as the garage wall is not too high, and there are reasonable lengths of brickwork returns each end, lateral stability under wind load wouldn't be an issue. If the roof joists are running parallel to the wall in question, they...
