Trying to find a sip supplier that can also design- it's for a very simple small outside utility room to put in a hot water cylinder, water softener, buffer tank etc. it's tiny... 3m x 1m footprint but dont have the time to learn all the details for such a small project - happy to pay someone to do it but I'm hoping to fi d a supplier who would do it for free (or very cheap)....

Some decent recommendations above.

I tun a factory that makes advanced timber frame homes. If the op wanted 600 panels I could help, but small scale needs the small outfits linked above.

For a small one-off, would it not be easier to design a simple timber frame and add insulation?

Or buy half an insulted garden building?
Or slap on a standard conservatory/porch with opaque panels instead of glass?

Easy enough to stick build a one off

Who’s going to build/assemble/finish it?

A typical sips kit is just the panels/structure; you’ll still need a base, waterproof the roof, membrane & batten & clad the exterior with something, fit a door etc.

If a builder is doing all the above then they might be more comfortable building it from timber; use 4x2 for the structure, put 100mm PIR between then line internally with insulated plasterboard for a thermal break. Or a million variations thereon.

If its going to be attached to the house, its going to need firestopping, and building regs approval.

Indeed.

I'm imagining this as a lean-to against the house, so the existing building exterior walls should suffice in general but out of interest how would you firestop the services coming (presumably) through the wall?

THanks All

Its not attached to the house- its about 2m away across our side access path.

I'll be building it - Did think about timber framing, but sip panels are going to be way quicker i believe and i am tight for time! Unless i've missed something.....

OK, SimplySIPS will design you a freestanding structure and the SIPs to assemble it. I had good service from them when I was making enquiries, although ultimately my build got more complex and detailed so I went down a traditional stick built structure.

However, see above about the other elements to finish the building. Will take a couple of weeks if doing solo and you have all the materials on-site.

Also, how are you running, protecting and insulating the feeds across the 2m gap to the main building? Guess you'll need 5 pipes minimum: mains feed, CH coil feed & return, softened water return, HW return, and probably a radial electric feeds for immersion heater and softener?

yes- but I'm only making the outbuilding- I'll open up the trenches to various places and then I've got plumbers and sparkies installing heatpumps and battery storage

I think I'd like a very precise specification from the plumbers to ensure they insulate the pipe runs adequately. Don't let them get away with just standard pipe lagging.
And then I'd look over their shoulder to make sure they followed it.

thanks Phil

They are using very very specific pipe for the plumbing which is costing us a fortune- its a silly amount something like £2k just for the underground piping....

We use an intumescent strip between the battens.

For a 3x1m structure it'd probably take longer to explain it to the SIP manufacturer than just stick build it... do the plumbers not know a jobbing builder that can sort it? These guys do "off the shelf" panels: https://www.premiersips.co.uk/product/147mm-sip-pa...

Pipework/ancillary spec is where the problem will come. For example, you need a spec for the slab that takes into account the pipe (and other duct) entry points. Make the ASHP guys double check it... the guys who did one for me recently did so, and still managed to forget a couple of wires because they specced it based on the ASHP they usually install (instead of what was actually being installed). Of course you can core drill through the slab to add another duct, but that's not a fun job.

When it comes to expensive pipe, I'd wager it'll be the insulated district heat main piping going in. That stuff has quite a long bend radius, and the installers will probably want the tails near vertical, so the trenchwork needs to take that into account. I'd get them to come and check it before your slab gets poured.
