Feedback on Dan Wood build

[kandgmitchell]

Well it's the second day on week 4. The ground floor screeding is being done as I type this. To date all the walls are up (they come fully glazed, partially rendered and plasterboarded). The roof has been tiled and guttering fixed, the first fix electrics are done, the first fix plumbing is done (wastes and supplies for basins, wc's etc come ready installed in the panels), the underfloor heating is in and the MVHR ducting in place. In the service room is the cylinder, expansion vessel etc for the ASHP and the external unit is here wrapped, sitting on it's pallet. They started on the 8th April and expect to hand over at the end of May.

 

We elected to use Dan Wood as a "half way house" - it's our original design (although with a nod to that sort of style). We didn't go extreme, much as we would like as I wanted a smooth planning experience, which we got. So, some of the standard Dan Wood bits we omitted. They can finish right up to carpets; handing over complete, save for the kitchen (too many choices apparently). We wanted a UK stair with closed risers so it could be carpeted. DW use bare wood, open riser and being aimed at the German market, the pitch is lower so the going messed up our internals too much. We also left out the doors (odd looking with the leaf rebated and closing against the face of the frame) and floor finishes save for the bathrooms. Those are now down to us.

 

We had to provide the foundation (insulated raft for us) and drainage/service connections. However, it's been a dream not having to organise anything once they sign off the slab as ok. Men turn up at 7.00am sharp and work to between 5 and 6. Saturdays 8 till 1 ish. All materials are either brought with them or turn up on time. Electricians, plumbers, and scaffolders are woven into the work and are here at the correct point. The electrician was here until 11pm finishing off first fix because the next trade needed it done. Every single day it progresses.

 

It probably isn't the cheapest way of doing it ( about £1730/m2 ex foundations) but the joy of not having any arguements with individual contractors makes up for it and there is no doubt the polish crew working on this house work damm hard and do a good job. You have to credit their attention to detail too. They obviously do this all the time as all the membranes are properly taped and sealed, the windows being inserted in the factory are done properly, etc etc. It's clear they have designed out issues over the years and have come up with solutions that work - hence the 20 year guarantee. 

 

We could buy the plot but needed to sell our house to fund the build. We are in a static caravan at present on site. Having reached retirement the certainty of getting the build done in a sensible timescale so we could get on with enjoying life was a big driver for this approach. Hopefully it'll be a family Christmas settled into a house this year instead of renting a cottage to escape the cold and damp of a 32ft static!

Really interesting! I didn't realise they did non-catalogue designs - it would be great to see yours. I had excluded them from my initial list, but sounds like it might be worth reaching out to them.

 

How does BC work with something so speedy?

[kandgmitchell]

The BC side is not too much of an issue. The foundation stuff is dealt with as normal and we did that so it didn't move as quick anyway. As for the superstructure technically it's a dpc inspection but DW cover the whole slab and a photograph did the job there. The rest is factory manufacture and BC seem very happy. DW do the pressure test and provide all the certificates for MHVR etc. Hopefully the final sign off will be smooth after we've done our bits.

 

We had seen an Adelia made by Scandi Huis, they have one on their factory site near East Grinstead. It was too big (and too dear). We had looked at DW but couldn't find a design we liked although some of the features we thought were interesting. So we came up with something along that scandinavian look which would not be out of keeping in the streetscene. MBC quoted and whilst we were considering where else we could go for an alternative quote, we spoke to DW just on a whim and they said they could get close. We had to drop a few bits, partly due to their system and partly due to cost so there was a compromise to be made but we're not far off. Just couldn't face several years of pain at our age just to get the fully glazed gable that you can't curtain anyway!

Thanks for sharing your experience with Dan-Wood . We are also considering this approach, once we find a plot.

 

I've read the foundation slab is specialised and very costly? 

 

Would love to know more and see some pics please.

 

Cheers

It's not a particularly specialised slab, it's just a little awkward (and has to be "right" dimensionally and level). They want a min. 150mm thick slab to lay their dpm over and then stand the frame on and fix down to. They then dress another dpm skirt off the bottom of the frame onto the vertical face of the slab. In a local DW build they used traditional foundations, built up to level with blockwork and cast their slab across the whole lot. That meant they needed formwork around the perimeter to contain the slab (normally the slab would be within the blockwork on a traditional build). Add to that their internal floor insulation used to comply with BRegs by itself but the last changes meant that some additional underslab insulation is needed as well.

 

We therefore used an insulated raft design. The formwork and under slab insulation is then covered all in one. The only frustration was that they wanted the upstand insulation removed so that their dpm skirt could be fixed to the vertical concrete. I removed that, stored it and will fix it back after completion. If you go that route then make sure the upstand is removable. We used Greenraft who use a plastic "fin" on a strip to join the horizontal and vertical, so removal was easy.

 

I've covered the foundation cost elswehere but it was about £20K (100m2) inc some drainage and a bit of cutting into a slope . One quote for the DW suggestion was £65K. I get the impression that DW are aware of the foundation issue and the rise of insulated rafts following the reg changes, but being based in Poland and feeding the German market it's not had the highest priority.

 

That lack of awareness is illustrated by them not offering a half glazed door option. This is due apparently to the Germans not normally having "back doors". After a concerted push by the UK sales people, they have now added such a door to the options for the UK market.....

Likewise i would love to see what is being built here, any pictures etc.

I would love to use Dan Wood to save myself some time and stress but their off the shelf designs aren't suitable and they are fairly coy about bespoke. 

Currently working up plans with an architect, will take them to DW once complete to see if they can quote.

[kandgmitchell]

Well this is entirely our original design but adapted for the DW system so they can do it (if you alter any of their standard designs by say moving a window it becomes "bespoke"). We omitted additional cladding due to cost and didn't do the glazed gable and fancy aluminium glazing as their system couldn't handle it. The interior is however exactly as we wanted. Sure there were compromises to make but we should be in, carpets laid and sitting on the sofa watching TV within 12 months of clearing the site and bringing on the static. We are both in our later 60's so didn't want a prolonged build on site, been there, done that. Garden to sort but can enjoy a warm modern house this winter after the last couple of renovations of old, cold "characterful" houses.

with this as the rear

Very nice. There’s a Dan Wood bungalow near us that went up in 6 months. 

[kandgmitchell]

This was 8 weeks from slab to hand over, with all services done and bathrooms tiled. We wanted our stair for space purposes and decided to fit our doors and skirtings. It's taken almost as long using local labour to do that as the poles took to put the thing up!
