Hi folks. We're getting a new Howdens kitchen. Hoped to install new Worcester Bosch CDi Compact boiler in 290mm deep wall unit (vertical flue through roof). Boiler is 280mm deep, so fits inside. But...the Worcester Bosch literature (and checked with technical team) insists on having 20mm...

Expert or non-expert views welcome! Being in the midst of building an extension on our house, I'm perhaps naturally thinking about how I would do it differently next time. Particularly about how to get the best bang for your buck on the build. The current extension is pretty standard 300mm...

Any thoughts on using elements board on walls in a bathroom around the bath/shower and on floor (all areas being tiled)? Looks like a good product but I don't have the experience to know about its pros and cons vs say hardiebacker. Cheers!

Am I going mad or does this sound right to you... Having removed a downstairs chimney breast in our Victorian terrace (upstairs breast gone and stack braced), the gaps on the first skin of the party wall (covering about 30% of the wall) have been patched/plugged with what looks like dry wall...

Thanks. A recent photo attached. It's the brick wall in the background. Once cleared of all surface plaster, the next step would be something like dot and dab plasterboard, then skim?

How so? In our setting, the neighbours side along our extension flank wall is about 300mm higher than our ground level. So it looks as though builder will put block along that section (and then DPC above the neighbours ground level). Make sense? Guess I am wondering how much of an issue, if at...

Have updated the post above - hopefully clearer.

The engineer's drawings for our single-story rear extension specify 3 courses of engineered brick (below external ground level) on the outer skin of the cavity wall. It looks like the contractor is planning on bringing the concrete higher and then starting straight away with about 1 course of...

Can I get some feedback on this CHS design for an extended ground floor flat (75sqm total)? Specifically, I'm thinking (1) the two radiators in the UFH kitchen/living area aren't needed and (2) to ditch the hallway radiator entirely. Thoughts?

So, the cavity wall infill below ground level provides strength against the pressure against it from the ground?

The engineer for our extension has specified a mass concrete fill to the new cavity walls, to a height at least 150 mm below the DPM. What's the purpose of this fill to the cavity? Thanks!

Building a side and rear extension on the outrigger of our ground floor Victorian terrace flat. I have an access chamber and a drain that runs down the side return into the garden and into a public sewer that runs across the back of the terrace gardens. Our neighbours' drainage goes into the...

Hmm, yes there is the question of how useful the above-floor foam is. It's quite thin (4 to 6mm) and has an R value of about 1.1 (vs 0.3 or so from typical insultation).

Contrary to everyone trying to work out how to insultae under the boards... I'm trying to understand the potential downsides of laying something like EcoTec Floor-Foam Insulation above the boards instead. I noted PUR/foam/wool products you'd use to insulate under the boards tend to have lower...

Update: we need a new floor. The planks were T&G, glued down on the side with the short tounge (though not the long tounge), which meant nearly all the planks have a snapped short side tounge now.
