Perhaps the primary reason is that it works quite nicely for the architects that fund it. It clearly does not always suit the customer, which is why there are so many topics posted on here questioning the wisdom. I seem to remember that RIBA were taken to task some years ago over their "fee scale" that they sought to impose and was found to be unlawful. I don't blame RIBA for looking after their members, but customers should be listened to more, as we are the ultimate paymasters.

Another vote for Spanish. Siga and SSL are 2 of the brands I know.

At least make sure you insulate the pipework between the boiler and cylinder. Quite annoying in the summer having a room heat up because the plumber was too lazy to do this.

Yes.

I use an architect who is very good at getting planning consent and is happy to pass over the CAD drawings. They are good at working out what will fit on site, look good, sell and finance well and help make me a profit. I would always expect the scheme they come up with to be buildable. I get others to do the building regs, planning conditions, amendments and detail drawings. If there is not enough information on the planning drawings, they can email each other. I often find that architects are more interested in producing attractive elevations than considering costs, building performance, H & S and so forth. On some LA planning websites you can search by Architect and work out who has the best success rate, which can be useful.

It is your money and you can do what you like. Make it clear to the architect that you will only be engaging them for the planning and you will require the design in electronic format for the detail and construction stages. If they are expensive, haggle for a better fee.

I use a Big Mutt for this sort of thing. Handy for removing skitings, door linings and general light demo stuff.

Another vote for the Aicos, although I spec them as mains with lithium cell backup. I have 10 plus and external sounder and a test switch at home.

I think it would be better to have the final ICs on your own land. Gutter outlet will be OK if all properly sized. Run all the drainage fairly shallow and just dive down where you are connecting into the main drain.

I have used Fermacell in the past. It is a real pain to work with, expensive and your sparky will hate you when they try to cut out backboxes. I also found it seems no less prone to mould than plasterboard. I have used Knauff Soundshield Plus in the past. Good value, sound attenuation, tough etc.

Standard practice at the onset of winter. Robbing b*stards.

I have to say @zoothorn that if your builder does not give you a smack in the mouth he is a saint.

I have not seen these used in a single dwelling - just in stairwells for flats. I guess because of this it needs to be anti tamper. £20 for a key seems a bit cheeky. Maybe explain to Velux that you were not issued with a key and see what they say.

Wait until spring. If you fill any cracks in the render, then insulate the lintel void you should be OK.

And you can scrap any plans to set up the Scalextric in the new loft.

The water could be getting in anywhere on the wall. The bigger the wall and the more exposed the worse it will be. It may be worth doing a close inspection next spring, when the weather is better. Check for cracks and hollow areas.

I may have this wrong but could it be lack of any cavity tray and weep holes above the lintel? This would normally be a DPC sloping down from the inner leaf and built into the brickwork above the lintel.

Red but scrap the kitchen IC. Use the bathroom near to utils in the main run inlet, with a bend just before the IC. Use the 2 inlets on the left of the IC for utils and kitchen, the R/H 45 inlet for the other bathroom and blank off the final inlet.

They look OK but I would be concerned if they needed replacing - flaking paint, rust etc. Also I like recessed fittings fire rated and OK in insulation without needing to add hoods.

Maybe worth CCTV or rod to check the rest of the drains on site.

You may be able to see the Environmental Health comments online. If they suggest a contamination condition it will almost certainly be added to your consent. If no contamination you will still need some soil information for soil type, bearing capacity and groundwater presence. Basement is easier if you have plenty of space around so you have room to work when you build the walls.

Would Aco type drains around the perimeter of your property work instead? You can feed downpipes into these and they will also catch the surface water from the yard. Not sure about your neighbours though.

Indeed, but that one seemed to have a huge amount of insulation and the walls were not built off the slab.

I would want to see a vertical DPC where the frame abuts the existing wall.

We have a house with flood resilient construction. The ground floor walls have full fill Celotex and the floors are beam and block with EPS under and around the beams. I am slightly concerned that the house may lift up in the event of a flood...
