By plain white do you mean a single flat panel ..?? Search fully finished white door - XL Joinery make them as do others.

Will be lucky to get 6m lengths of C24 9x2*. Is it going to be visible inside as that’s the usual reason for using glulam over steel. Point loads on a site fabricated beam doesn’t sit comfortably with me - sorry..!! Standard glulam beams are off the shelf these days too so shouldn’t be an issue. * oddly just checked and TP hold 225x47 in 6m lengths ... or some branches do..! Most I seemed to get was 5.4..!

I’d also want the SE to confirm the glulam replacement is correct, and also I would get the TF company to credit the cost of the beam as it will not be as cheap as bolting 3 9x2 timbers together. What is the beam length out of interest as 9x2 you will struggle to get longer than 5.2m. Any joint to make it longer should be scarfed and staggered.

It’s a flat topped attic truss really but you could struggle to find someone who can manufacture them in one piece with the ability to support the flat roof structure. I would go steel portal frame and cut roof and work from that.

Lots of duct tape and either make them higher than the slab by a good way, or just below and encase them in spare polystyrene so you can break them out after you have power floated the slab.

Is the space in the attic to be used ..? If so, could be as simple as building a steel box of UB and UC and then build a cut roof over the framework. “Long term” is an interesting term..! Some GRP is certified for 25 and 30 years, and if it’s not being walked on it could last even longer. Flat sheet lead could last even longer but would need to be properly engineered due to weight but could last decades. All down to cost and skills available.

The rear slope needs to be open rather than a parapet - water then flows over and down that roof plane

Detail is in the ridge finish. Most have a recess of at least 1-2 tiles to allow for the "flat" section to have a reasonable upstand to ensure waterproofing if the flat roof floods. Snow can also be an issue with an enclosed flat roof. I would say the issue you have there is that there is a parapet all around the flat roof so any drainage will have to be through the roof membrane itself. That has to be watertight and will mean rainwater will go inside the building envelope which has to be managed and designed very carefully. A better approach is a 3 sided flat roof so one side drains naturally and there is no need for unnecessary flat roof penetrations. Costings...?? The flat bit - a flat roofing contractor should be able to do this easily. I would look to GRP or something with a very long guarantee as it needs to be perfectly detailed. The remainder will be comparatively simple - its just a tiled roof of x square metres, with y metres of ridge etc.

So on a 165sqm part conversion (45sqm) part new build that was basically rip the old bit to 4 walls and a steel, mid point was fully wind and watertight with UFH (in slab) and heat pump in at around £60k. Big benefit of having a room in roof design and being able to utilise that roof space to the maximum. I would say on a square metre basis though, the conversion part has cost more per sqm as insulation cost is much higher (internal Kingspan) and floods have had to be replaced etc and the cost of removing the roof was much higher than anticipated. Hindsight would have seen it demolished as it’s created a fair few issues (not being square to start with ..!) however any cost saving (inc VAT reclaim) would have been swallowed by additional costs in compliance services such as air tests, DER/TER, and also applying for planning as the permission is for conversion not new build.

Yes you can run overground and I would as it’s a simple job of moving the pipe into a trench and sticking a pair of connectors in. Using lead - even temporarily - is just not something to contemplate. Trace it and rip it up and weigh it in - it will pay for the extra connectors ...!

Legally you can’t use lead pipe in a new connection so it’s a non starter .... water company won’t reconnect it either. Duct to the boundary and start again - do not use the old pipe ..!!

This stuff works. Leyland Hard Wearing Paint

Plaster doesn’t need a key for paint to stick ... and the easyfill will soak up any dust - if in doubt just wipe with a wet rag.

JCB will go through pretty much any soil type. Issue is when they hit rock that the back actor on them doesn’t have the power. Switch to a narrow bucket and double dig is the answer.

Before you fill any more holes go over it with a coat of white emulsion. You’ll see the worst ones better on a white surface and you can just fill and go with the next layer before you paint again. I use this stuff for small dinks and scratches as it’s white and hardly noticeable and dries really quick.

Never heard of them so not quite sure about the “market leader” comment ..! I’d spend the extra £35 and get the GROHE one. Geberit are good - you can find them on eBay a fair bit too.

Yep - straight on, no dicking about with PVA, SBR or peeing on the walls ....

Easyfill every day of the week....

It’s got some bad reviews but is 4.7 out of 5 overall ..??? I had an issue and it was sorted straight off. Their website does say some things are not stock items and take 3-4 days to deliver but that’s like anyone. No supplier holds stock of everything as they just would sell it all.

Isn’t the bottom switch the one I put for heating controls ..?? Could always take the plate off and take a photo ...

Chisel is the manufacturers recommended method - they create a weak point in the sinks to allow for this. The sink material isn’t tough enough in the centre to take a drill bit and it may wander and a grit edge hole saw will skip on the glaze and scratch it ...

MKM are cheaper than kitchen warehouse for multi panel ... ? QS Supplies are reasonable until you need after sales and then it is a bit hit and miss tbh. Just ordered from BBC in Bradford and only issue was a late delivery as the courier damaged the tray before it got to me - swapped on to a next day delivery and no issues. By wall hung do you mean semi pedestal basins ..? You can get a wide range from Solutions in Sutton In Ashfield and they have a trade range that is very good and on par with Wickes etc for pricing. Don’t be tempted to go B&Q as quality is shocking ....! Just have a look at the ones on display carefully and you can see even glaze colours don’t match ...

@newhome I have it on good authority that @Nickfromwales loves working in attic spaces at this time of year - something to do with a diet .... As @JSHarris said though, needs a decent route to get to it and the filters may not need cleaning if it hasn’t been run ..! you may hear something from the exhaust fan as that will project noise outwards - the intake may well be quieter. And as for tracing wires, you know who’s best at that ..!

I wonder how much is laid ..?? Can you count the layers ..? I wouldn’t get rid if there is less than. 300mm as another layer would help a lot.

This one was the first on a search - plenty more similar in the 2.5-3kw range which are ideal for what you want. https://www.cooleasy.co.uk/categories/easy-fit-air-conditioning/high-wall/2-6kw-midea-blanc-wall-mounted-system.html
