    Chimney, no flaunching.

    Hello, I have a woodburner off one pot and I’d like to put another one in off the second pot (they lead to ground and first floor levels). The second pot has a ventilated cap on it (I’ve removed it in the picture) but when it rains there is a slight drip down to the open fireplace. I can see...

    Box Bay window

    Thanks. The structure will only project 400mm from the wall, but the window is 143kg so with the structure call it 170kg. I suppose two people could sit on it (plus the dog) so lets say an additional 200kg. With a 1.5 safety factor that would be around 550kg. With a span of about 3.4m, would...

    Box Bay window

    Ok thanks. I’ll investigate the existing support joists. I’d never heard of gallow brackets. Did a quick search and came up with this link. The video was a bit if an eye opener! o_O https://www.labc.co.uk/news/how-to-get-it-right-removing-chimney-right-way-video-showing-wrong-way

    Box Bay window

    Hi, I’d like to replace this window: With this: Inside it would look something like this: I was wondering what the best way of framing it was. I was thinking 6 x2 verticals bolted (wall anchors) against the wall either side, 4x2 horizontals something like this: The existing bay...

    How to build this “gable”

    Bit late now:(. The height from the top of the rafter to the lintel flange is 200mm. That doesn’t seem too bad does it? If I want the fascias to match the rest of the house then I’m thinking I could but a 4x2 timber horizontally across on the lintel and then just clad that same as a...

    How to build this “gable”

    Well spotted ...yes it’s an eaves lintel. Was intending to do soffit/eaves as show in blue below dropping timber down to support as it’s a shallow angle. Will that work?

    How to build this “gable”

    How to build this “gable”

    Hi, I’m struggling with this detail circled: I’ve built this far: I’m going to bolt new rafters to old to end up with a 20 degree slope: But, what do I do at this end: Do I extend the wall plate across the cavity: Like this: Help please!

    Extension roof join at old roof

    Hi, I’m currently building a front extension for a new entranceway which should look like this when finished (it will be a slate cladding finish not brick). In the picture below I’ve arrowed the bit I’m struggling with: I’m thinking that the walls and wall plate height will match...

    Reinforce existing retaining wall?

    Thanks Woody. Will do! Finally got some drawings from a structural engineer. Does anyone have any top tips on building it? The spec says B503 mesh or H8 L bars between wall and slab with lap length of 450mm. How would you even do it with the mesh? I’m thinking it’s a case of : 1. Excavate...

    Distance of openings from wall

    It’s a good point about the wall ties. Both leaves will be blockwork so would need thin ties which don’t seem very common. Have found some here http://www.tackburn.co.uk/wall-ties.html but it’s probably not a good sign if the builders merchants don’t stock them! Just read your post Woody and...

    Distance of openings from wall

    Thanks for the reply Tony. Why thin joint? It’s only a small extension, I’m doing most of it myself and I just fancy giving it a go! From what I’ve read it’s more common outside of the UK. I’ve read this ...

    Distance of openings from wall

    I’m planning to construct the small front extension (the white rendered part) out of thin joint aircrete blocks. In the picture I’ve arrowed the wall which breaks this rule: OPENINGS AND RETURNS An opening or recess greater than 0.1m2 shall be at least 550mm from the supported wall (measured...

    Reinforce existing retaining wall?

    I have a retaining wall that is no longer fit for purpose. Should I start again or modify? In the picture below, the gap between the retaining wall on the left and the house on the right was filled with rubble and resulted in damp. I was thinking of something like below. The new wall...

    How to build front extension

    Dear All, Finally got planning permission and I’m looking at what my options are for building my new front entrance way. The slight complication is that a 6m long retaining wall is required as part of the design (1.5m high of earth to be retained). I’m thinking standard footings with steel...

    Kitchen extension on slope over terrace

    Yes, all fair points. It’s more the how I would do it rather than the why! I’m thinking two 140mm deep by 100mm concrete lintels could be used to span the gap then build on top of them. On the side I’m looking at there is only a small wall to build with a window above. I could use timber frame...
