Yes, sorry, SAP. Min is B85. I also wrote a project description - they want an idea of the overall project "eco" credentials. I focused on reuse of materials from the demolition, and my planned zero to landfill waste policy.

For us, about an inch thick stack. Latest CC statements. 3 month's pay slips 3 month's bank statements for all accounts Proof of deposit Detialed costing for project (combo of QS estimates, quotes, all signed off by architect) Proof of address and identity (utility bills, passport) Current mortgage balance and 2 years of original statements. You'll find that will be universal for all mortgage companies.

@darringo just started! Documents went in a couple weeks ago. Following up on one or two missing documents at the minute. So far experience has been positive. They are very thorough and detialed. They actually rang my coany to check that I work there... You get allocated a dedicated agent, so you have a direct line of communication.

Also like the fact that it's a small house built on a reasonable budget. Not the usual multi million pound gargantuans that are usually revered and win awards (remember that rediculous hotel complex like "home" in Kent that won home of the year a couple years back?)

Who was the ICF company? Kore have included a quote for services from Tanner's for the EPS raft.

Perfect. I'll use my architects preferred engineer to oversee and check the manufacturer's calculations. She'll be coming out next month to do the soil samples anyway. As I'm an engineer (not an SE tho) and project manager, I should be able to manage any changes or conflicts effectively...

Hi. We're building using a passive raft foundation, ICF walls, concrete decking system for intermediate floors and an EPS panel system for the roofs. For each of those elements, each supplier has offered engineering services to do calculations etc. Normally I'd prefer a single SE to do all of this... But a lot of these are novel and proprietary systems and I'm not sure I could find an SE that is competent for all of these items. My local SE firm has never done ICF before... Anybody done similar, and what did you do?

We have our ES coming off the dressing room. So two doors between ES and bed.

That's good value. We would have charged £225 per half day on site.

Sorry, a local company here in NI, CES quarry products.. I know our concrete and quarry material costs are a fair bit cheaper here than in GB. Yeah, Kore will be doing structural design, definelty required if you're doing something other than a pure timber construction. I see base prep being key... I think I'll be retaining my ground works company to help with this. You're right about setting out.... Surveyor for setting out all corners is key. Luckily for me that's my background.

On paper, it should be better value compared to traditional system. Largely due to less excavation, simpler excavation (no marking out of trenches), no rising walls, no secondary screed, smaller concrete volume. You're putting more money in to the formwork tho. But it makes eveything else simpler.

I've costed up insulated raft for our 100m² footprint comes out at about £35m² largely DIY. Obviously if going for a MC, you would double this.

I fully intend on installing my own Kore raft. And I'll be doing the pour as well... Self compacting concrete. Very little shovelling, moving, floating or tampering to do. It behaves more like a screed. Look up some videos. I think I will talk the concrete guy into being there tho... Cost wise, self compacting is £80/m³ vs £60/m³ for standard c35. But a lot cheaper then me getting a crew in for a day.

You'd be right. If we need to encase PE pipes, we normally insert in to a steel sleeve or wrap in a plastic liner before pouring. In a domestic situation, bring the pipe up through a pvc pipe.

Unfortunately I've been working in Dublin this week and not had a chance to speak to him... Will be speaking to him this weekend tho as I need his input on my proposed vent locations.

@Russdl I'll find out tomorrow for you.

My neighbour that installs MVHR systems insists on a coarse filter before the 2.5 filter. Massively increases the life of the filter, but more importantly delays the pressure drop as the filter clogs.

Similar here but I'm choosing not to use a main contractor. I'm planing to build the ICF forms myself, then get a contractor in just to to the alignment and pour for each story. I'm the. Ordering the floor slabs as a supply and fit, and wil be using a small builder I know well to do all the internal carpentry. As long as you get the design details right and communicate them to your contractors then it comes down to the work ethic and skill of the workers.

Making savings by simplifying layout (most of work surface on island) and few units by moving storage in to pantry. Will likely fit it myself.

If it were me, I'd be taking £1k off the kitchen/bathroom budget and getting the best windows you can afford. Fabric first. Actually, that's what we are doing to get the standard of bi-folds we want, kitchen budget, down from £10k to £7.5k. kitchen is easier to replace than a window system in 10 years time.

Super king all the way.

For our estimate for our mortgage we included everything from groundworks to floors and kitchen. Doesn't include landscaping, driveway, garage (future item), demolition of existing house, and utility costs (being done before first drawdown, and only electric). Location has a huge impact on cost... I've been costing up concrete, windows, site works etc and they are all substantially cheaper than what the UK industry tell me they should be. E.g. concrete from £60/m³ instead of the typical £80/m³. You might find same story in N Scotland. As regards accurate costs... Best getting a template and then going out and getting ballpark quotes from individual suppliers. Don't bother with a QS.

Our design has a partial basement that is only open to the south side. Space is precious on the ground floor and ceilings are vaulted on the first floor... So basement is only option. Architect is proposing inlet and outlets of MVHR to be on the southern basement wall. Not ideal, but not a huge issue. ASHP also to 3b close by. Issue I've raised is that these are all underneath a ground floor balcony. It will be 3m above the basement ground level and will only project 1.5m out and will be a slatted deck. Is air recirculation a potential issue here? We can still get the pipes 2m apart, but both will be under the covered area. ASHP can be about 4m away, but still under the covered area. Very rough sketch landed in there now. MVHR ducts would be around the area annotated "E" on the drawing. Thanks

Do they do a triple glazed option? I see from the Sieger page it's *possible on request*

This happened to us a couple months ago. Whole system went off for about 20 seconds then stopped. Same thing the next day. Been fine ever since! Gremlins.
