Look at the specification on your SE drawing. You won’t get an answer here.

As long as it’s a recognised system it will be fine. Don’t just slap a bit of pink board around the beams. Doesn’t work as simple as that.

No.

The extension doesn’t need a SAP. If you can’t get your glazing below 25% of the floor area (minus the area of glazing removed) use a calculated trade-off or get a SAP done to do an Equivalent Carbon Target calculation. Most companies shouldn’t need plans - they should come to the house and take a few measurements and ask you a few questions about what insulants you used.

Where does the toilet roll go? Do you have to lean to the back wall to get a few sheets?

Nor was he. Took him years to build his house though!

Petrocelli?

Why did you wait so long to get BC out to do the final inspection? Bathroom door: There is a requirement for an accessible wc door to open out. Do you have a separate wc or is the accessible wc in the bathroom? Where I am as long as the door does not impede on the clear space it’s fine. Where a clear space is in a bathroom the door can open into the bathroom but if the wc is quite small and the door would impede the clear space if opened in the door should open out. In your case I wouldn’t be too worried about opening the door into the bathroom. In reality opening the door out can cause more problems - someone walking past could get a smack in the face! FR to steelwork: The requirement for FR of structural steelwork is a standard requirement - even if it’s not on the plan. Standard plasterboard won’t achieve 1/2HRFR. Intumescent paint is the easiest option. Water membrane system: Cannot really comment on the water membrane system other than to suggest that you send him a sketch of what you did with an accompanying sketch from the supplier/manufacturer. Timber frame specification: If you can’t get the TF company to give you a structural design certificate invite your local friendly SE around for a cup of tea and ask him to indemnify the structure. If BC noted these things six years ago they really should have told you at the time they were inspected. Could they have told a contractor on your site? I can understand your frustration but to get your completion certificate you will unfortunately have to comply with the request from the BCO. Good luck.

Ask Unilin (was Xtratherm) to do an interstitial condensation risk analysis for you. They can do it over the phone and email you the results within 30 minutes.

Inside for all doors. No architraves in the hall unless you line the recess and put architraves on both sides.

Don’t be put off putting in a very large dormer to the back of the house. Some can look very good.

I think it’s called 80’s post modern too high to clean or do anything with.

Looks a bit small for a double bed and two bedside tables/lockers.

Where does the bed go?

Knock it down and start again.

BC couldn’t care less if it was drawn on the back of a fag packet as long as the information was there.

Either will work as long as you make sure the DPM is overlapped with the DPC in the walls.

You might want to check if you need to make a BC application - you do in my jurisdiction.

Did you make a BC application?

Use the black brick that you’ve used for the plinth.

I never understood why anyone would want drawings on site - builders never read them anyway!!!😂😂😂😂.

You need a VCL- it’s normally only 500 gauge - quite light really. Alternatively if you’re using PIR with a foil face tape all the joints. A separate VCL is easier though. I am presuming the DPM is already laid below the insulation.

Ugly as f**k!!!!

If you’re getting condensation in the roof space you should try and increase the insulation in the roof space making sure that you overlap insulation at the eaves and provide adequate ventilation. However lap vents aren’t great. Where the insulation is at ceiling level you should be providing 10,000mm2/m ventilation at the eaves and - depending on the span and pitch - 5,000mm2/m ridge ventilation. For insulation between the rafters the requirement is higher. Take a look at Glidevale’s website for products and take a quick look at the White Paper which explains a little bit about ventilation in buildings.
