Will the en-suite get a lot of use? We have a sliding pocket door on one of ours. They are annoying to open and close frequently. Hard to do quickly without banging against the stops. If yours is between en-suite and walk through wardrobe perhaps it would be left open most of the time thecen-suite is in use?

Is there water getting into the cavity higher up? Blocked gutters?

I know someone who built a nice 3000 sqft house. It cost them about £1.1m to build incuding the plot, everything. It's probably worth £800k.

Perhaps gang up with the neighbours and write a joint letter of complaint to the water co. Ask them to investigate. Does the house have a big cold tank in the loft and possibly pumps to boost the pressure for other outlets? Combi boiler or stored hot water tank?

Possibly. What time of year was it laid? The air is more humid in summer than winter so if it was laid tight in winter it will be under lot of stress come summer. That and a very hot floor due to sunlight would be my guess.

I think the requirement for houses to have charging points was introduced in June 2022. Thats when Approved Document S was introduced. So if the Building Control Application for your house was submitted before June 22 then you may not need one to meet the building regulations. If after June 22 then I think you do. However if the specification/contract for your house says it includes a charging point then I would expect one to be provided regardless.

https://www.watersafe.org.uk/advice/common_plumbing_questions1/pressure/what_is_the_minimum_water_pressure_that_a_water_supplier_must_supply/ Unfortunately water companies are only obliged to provide 0.7bar measured in the pipe between the main and your boundary so the 9L/min mentioned above isn't binding. Got any near neighbours? Ask them what they get. If they are in similar houses and get much better then check all the stop cocks are fully open. Some houses have pressure reducing valves to prevent taps splashing everywhere. In my experience these pressure reducers seem to need adjusting every few years as the flow reduces gradually over time. There is usually a screw sometimes hidden under a label. Does the kitchen tap have an aerator or strainer or filter in the supply tails? Sometimes these scale up reducing flow rate. Is it a new house? Old place with a long driveway/supply pipe?

My guess is high humidity has caused them to expand and bow upwards. If the boards were stuck down its possible the sun has softened the glue near the window and the expansion has caused them to pop up.

I'm not sure how that can happen unless the T&G has failed?

I think I was probably about that.

Are you doing a knock down and rebuild or building a new house in back garden or ? Eg Will the new house have same address? If its going to be a new address you may want to get that onto sorted first via the council so it's on all the databases. Sometimes service providers cannot create an order on their computer if they can't identify the address. Getting phone connections sorted can be pretty frustrating. I think in theory for a new house you can go direct to Openreach but some have tried that only to be referred to a service provider like BT. Openreach provide a developer portal where you can register new developments as small as one house but sometimes they say they can't do anything without an order from a service provider.

No. Only analogue phone lines.

Have you checked you have sufficient ventilation at the eaves. You typically need the equivalent of a 10 - 25 mm wide slot the full length. That's a lot of 80mm round vents, perhaps 4 - 5 per rafter bay. Sometimes you have to have two staggered rows to meet recommendations a one line won't fit. https://nhbc-standards.co.uk/7-roofs/7-2-pitched-roofs/7-2-15-ventilation-vapour-control-and-insulation/

For Thermaclass Cavity Wall 21 the board size installed is 1190 x 450mm (installed). That's an area of 1.19 x 0.45 = 0.53 sqm. So work out the area of your walls and divide by 0.53 to get the number of boards needed. In the 140mm thickness there are 64 boards per pallet so divide the number of boards by 64 to get the number of pallets. Perhaps add 5% for cutting/wastage? Shop around/haggle.

Online Quote for triple glazed sealed units. Lots of options. Not used myself though. Looks like delivery by 26th. https://www.glasstops.co.uk/order-online/triple-glazed-unit-rectangle.html

Existing services disconnected/turned off in the road? Any planning conditions that say "Before work starts..?

I you plan to sell in a few years I'd be careful about costs. It's not hard to build a house that is worth less than it costs to build.

We just have some low level wall lights around the house mostly where there are steps and the patio. Quite like them as the give a certain "atmospheric feel".

I remember how they would fill up alarmingly when you flushed, then just before overflowing there would be a gurgling woosh and it would all disappear.

Welcome to the forum.

Most (all?) pans have a round outlet pipe but on many it transitions to something not perfectly round when you look down the pan. In my many years of cleaning pans (I'm over 60) it's best to avoid the ones with are very "square" as you get err build up in the corners. Most toilet brushes are round and don't always reach into the corners of the square if you get what I mean.

Depends if you think you might want to use the water. I think most crate systems are just storm attenuators so it will all empty out before you can use it. Most tanks are the opposite in that they don't provide any storm attenuation when full. I believe it might be possible to get tanks that do half and half. Eg they automatically drain until half empty so you have half the capacity acting as a storage tank and half providing storm attenuation. I havent really investigated these.

Old whiskey barrel with flowers in?

We had same problem. Our plot was/is on clay and a percolation test showed soakaway wouldn't work. Also have a piped ditch along the edge of the road. When we applied for PP one consultee said "They wouldn't want us to make flooding down the hill worse" so we got hit with a planning condition to get the drainage approved. I proposed an underground rainwater storage tank with overflow to the piped ditch under the road. We wanted one anyway. The planners approved it even though it doesn't provide storm surge attenuation if its already full. Its been very useful when there is a drought as we can use it to water the lawn or the veg plot. We have even pumped the water 200 yards across the village green to an allotment. Its not used for anything in the house. Too much leaf mould gets into the tank for that. As far as I know the EA or County Council wernt involved, unless the planners consulted them a second time but I doubt it as approvalto discharge the planning condition came back too quick. If you don't get hit with a Planning Condition I would just propose discharge direct to the ditch to the BCO and see what he says. Perhaps write on the drawing that you have Riparian Rights. If it becomes an issue then perhaps propose a crate system for storm water attenuation or rain recycling tank. I wouldn't involve the County Council unless someone tells you that you have to.

In winter its obviously cold outside and warm inside. The 25mm insulation effectively "moves" part of the rafter from the warm side towards the cold side reducing its temperature. This increases the risk that water vapour may condense on the rafters. Ideally you would get a condensation risk analysis done. However my understanding is that normally upto 1/3rd of the insulation between and 2/3rds above the rafters is ok. You have 25/125 or 1/5th between and 4/5ths above so I agree with the BCO, it should be fine. To reduce risk perhaps seal the gaps between the 25mm insulation and rafters to reduce the amount of water vapour,pour that can get through to the cold side and add a vapour barrier before plasterboarding. Avoid down lights that need big holes cut in the vapour barrier.
