Urgent - Granny annexe company or builder reccomendations. Start ASAP

12 replies

time4change33 · 06/02/2026 11:11

Hi all, hoping someone here might have some advice or recommendations because we’re honestly panicking a bit now.

My parents (both in their late 70s) are supposed to be moving into a two bedroom garden annexe that was meant to start this week. Long story short, the builder has completely let them down at the last minute – lots of excuses, delays, and now basically admitting they can’t start and might not be able to do it at all. This has come totally out of the blue.

The really stressful part is that my parents have already sold their house on the basis that this annexe build was going ahead. Completion is imminent and there isn’t really a backup plan. Renting short term is tricky (pets, furniture, cost, etc) and they were relying on this being built asap.

The annexe itself is quite substantial – not a little pod or studio. It’s a proper two bedroom granny annexe, designed specifically around their needs (step-free access, wider doors, accessible bathroom, space for carers in the future if needed). Because of that, the companies that just offer standard models or “off-the-shelf” units won’t work for us. We’ve already been told by a few of those that they can’t customise enough, or their lead times are 6–12 months which we just don’t have.

We’re based in Redditch, just outside Birmingham, and ideally need someone who:

  • can do a bespoke garden annexe
  • can start very quickly (or at least do groundworks / foundations asap)
  • has experience with larger annexes, not just tiny garden rooms
At this point we’re open to any suggestions of companies, builders, specialists, or even advice on what we should do next. Has anyone been through something similar? Is it realistic to find someone who can step in quickly or are we being completely naive?

I’m really worried about my parents as this has been incredibly stressful for them and it feels like everything is up in the air now.

Any help, recommendations, or even hard truths welcome. Thank you if you’ve read this far.
(Also sorry if this is a bit rambling, head is all over the place!)

Presumably you've already got the planning, architects and building control plans so you could try to get quotes from alternate builders. A lot of jobs are falling through due to rising costs and people lacking money.

Geneticsbunny · 06/02/2026 12:10

I would be really careful. Anyone who has availability for this sort of job immediately without charging a huge extra amount to cover the extra man power to cover doing an extra job on top of their existing commitments is likely to be a complete cowboy.

Honestly renting for 6 months to a year is a far more sensible idea and will possibly be cheaper.

Tortephant · 06/02/2026 13:08

Totally agree with @Geneticsbunny

I would also suggest you start viewing this as a small house build not a large annex. Positioning will be critical to finding the most appropriate builder and trades.

as @Rollercoaster1920 asked, are all the permissions granted and technical specs ready? If so then go out for quotes. The best people will have a lead time particularly if you want the to project manage too.

also ask locally for recommendations.

get your parents reassured by finding a rental for a year. Look at Airbnb type holiday lets to. You may be able to do a deal with them and just get all parents things in storage.

this is all going to take longer than you think

When I was researching for something like this, I heard good things about this company, if this is the kind of thing you’re looking at. I don’t like the traditional log look but the modern scandi ones are nice. From memory I think they have a degree of bespoke design too.

Thanks for the replied, I really appreciate people taking the time.

Yes, we do already have planning permission and drawings etc, so at least that part is done (thank goodness). We are starting to approach other builders but it’s just the timing that’s terrifying. I completely take the point about costs and availability and we are being very cautious , the last thing we want is to rush into something and end up with someone unreliable or worse.

The difficulty with renting is my dad’s health, which I probably should have mentioned originally. It’s been deteriorating quite quickly over the last few months and one of the main reasons for doing the annexe now was so they could be settled somewhere accessible and stable, close to family, without having to move multiple times. Short-term rentals, stairs, unsuitable bathrooms etc are all becoming a real issue, and the uncertainty is really taking a toll on them both.

That’s why we’re trying so hard to see if anything can be done to get the build moving, even if it’s just groundworks or foundations to begin with, rather than everything being in limbo. I do hear the warnings about cowboys though and that’s honestly one of my biggest fears at the moment.

If anyone has been through something similar or has managed to find a reputable builder at relatively short notice (even if it meant a phased approach), I’d really welcome hearing how you handled it. At the moment it just feels like every option has risks attached.

How long its going to take is my biggest concern :(

I will check out Norweigan Log

Thanks again

@time4change33 Are you building bricks and mortar or buying a kit? Sorry I’m a bit confused. If you’ve got an architect, then ask them to source you 3 builders they’ve used previously and get quotes and availability. Don’t immediately discount someone. All I can say is my builder brought forward our work by 6 months with two weeks notice due to people unexpectedly pulling out. Though this was a trusted and known builder to us. I’ve also had quotes previously from sourcing local well used family firms, multiple builds in our village, etc. It takes time to research the more reliable contractors but well worth it

ThroughTheRedDoor · 06/02/2026 17:27

Pm'd you @time4change33

SoScarletItWas · 06/02/2026 17:27

I’ve messaged you with a recommendation.

Agree with PP to ask the architect for people they’ve worked with.

time4change33 · 07/02/2026 11:38

Hi guys, thank you so much again for all the advice and recommendations, its honestly really appreciated.

I’ve realised there’s another layer of complexity which I wasn’t fully aware of before (this was all being handled by my OH). Apparently we already have a Certificate of Lawfulness in place for the granny annexe, but it has to be built in a very specific way. From what I understand, that means we can’t just use a traditional builder unless we go back through full planning again, which obviously isn’t ideal given the timing.

The annexe has been approved under the Caravan Act, which I’m only just getting my head around. It’s still a proper two bedroom garden annexe, but it has to meet the legal definition of a caravan, which affects how it’s constructed. That seems to rule out a lot of “normal” builders, which explains why this is proving so difficult.

It looks like companies such as Norwegian Log do meet this criteria, but they are eye-wateringly expensive. So we’re now trying to find any companies or specialists who can do a bespoke granny annexe built under the Caravan Act, ideally timber or steel framed, and who might be able to help in a relatively short timeframe.

I appreciate this is all quite niche, but if anyone has experience of lawful development granny annexes, or knows of any companies that don’t just do standard models and actually understand this type of build, I’d be really grateful. Even pointers on what to search for or who not to use would help at this point.

Sorry for the essay – this whole thing feels like a crash course in planning that I wasn't privy to 😩

Ahh that sounds like a bit of a nightmare, especially given everything you’ve got going on with your parents, I really feel for you.

We were in a vaguely similar position and actually ended up using a company called The Granny Annexe Company who do exactly what you’re describing. Ours was also built under the Caravan Act and I remember being told at the time that it isn’t all that common, which caused a bit of pushback and confusion early on. They were really good at dealing with that though and eventually got everything over the line (sounds like you’re past that hurdle already at least!).

They’re not a massive firm, so I’d be honest and say they might struggle to slot you in immediately, but from what you’re saying they sound pretty much spot on for what you need. Our annexe was a steel-framed granny annexe, built on these huge screw piles they literally drove into the grond, it was actually quite impressive (and slightly terrifying!) watching it go up. The whole build took about 5 weeks once it started and we absolutely love it.

Not the cheapest option, but given the stress and complexity at the time it was worth every penny for us.

This is their website if it helps:

Really hope you manage to find a solution quickly, keeping everything crossed for you 🤞

time4change33 · 07/02/2026 17:39

Thank you so much for this. I’ve had a look at The Granny Annexe Company and they actually seem exactly what we’re after. There’s going to be quite a lot of “pre-work” needed before the annexe itself can even start, so it’s reassuring that they seem set up to handle that side of things as well rather than it all being a problem.

I tried calling earlier but they were closed, so I’ve filled in the online form and will be ringing first thing on Monday morning. Fingers crossed 🤞 I’ll definitely update once I know more.

Would also really love to hear if anyone else has used them or knows someone who has, good or bad experiences with them very welcome at this point!

Did you go with them in the end? How’s it going if so.
