It is pretty funny how AI completely ignores property lines and just casually redesigns your neighbors yard too. It seems generative models really do not care about real estate boundaries 😁

This might be the most accurate description of living with solar tech I’ve read in a while 😁

When I did a hip to gable a few years back we had the engineer specify stainless angle brackets resin fixed into the inner leaf only. Outer leaf was kept completely non loadbearing and tied back with wall starters just to carry the hung tiles. Biggest lesson learned was to run the DPC up behind the studs and lap it properly into the cavity trays, otherwise you risk hidden damp bridging later on. Hopefully this helps

Ik this post is a bit old, but it’s worth pointing out that Octopus won’t validate an export MPAN until the DNO has updated ECOES with the new technical details, and sometimes that update lags behind the G99 approval even when Grid say everything looks fine. In my case, the installer and DNO both said all good, but the ECOES record still showed the site as import-only, so Octopus’s system auto rejected it twice. Once the DNO repushed the export MPAN into ECOES, Octopus processed it within a week and backdated payments. If u haven’t already, i’d push specifically for a screenshot or written confirmation of what ECOES actually shows for ur site, rather than relying on what each party says separately. Hopefully this helps someone who encounters smth similar

Few people mention this, but if you’re aiming for a genuinely healthy house, consider integrating clay or lime plaster for internal walls, it passively regulates humidity, reduces VOCs, and creates a noticeably more comfortable indoor climate without relying entirely on tech like MVHR.

That sketch looks great and the inspiration photo is absolutely spot on – love the simple, modern look with that big glass window framing the view. I was actually in a similar boat not long ago trying to get a compact sauna built on a tight budget (also around £3K), and it’s definitely doable if you find a small local outfit or even a skilled independent builder. I’d suggest checking Facebook community groups around Tunbridge Wells or even posting on Checkatrade and Rated People with very clear specs and your drawings – I found a guy that way who was happy to work with my materials and plans. Also, worth calling local carpenters directly, some of them are surprisingly open to side projects like this. And if you end up building it yourself or part-DIYing, feel free to reach out — I’ve got a bunch of notes from when I did mine, including tips on moisture protection and window fitting. Good luck, it’s going to be a great setup!

Your home looks fantastic! Modern but still warm and welcoming. Thanks for sharing such a detailed review. It's really encouraging to hear how smooth and transparent the whole process was, especially around pricing and scheduling, which are usually the most stressful parts of a self-build. That fixed-price model with no surprises, even during material cost spikes, is impressive. Also love how efficient the house sounds year-round 19–22°C without much heating is no small feat. You’ve clearly built something future-proof and thoughtful.

You're in a very similar position to where I was a couple of years ago — plot already owned, initial design by a relative, and planning advice with a long list of surveys. It does feel like a leap of faith when you’re committing real money before having a firm grasp on build costs. That said, your budget of £300k for 100 m² sounds achievable, especially if you’re flexible on finishes and open to moving in before it’s 100% done. The living roof and floor-to-ceiling glazing could eat a chunk of the budget though, depending on spec. I found it totally possible to get an architect just for technical drawings, but some were pickier than others — it helped to ask smaller, local firms. Also, having a main contractor manage things was a life-saver for me since I didn’t want to be hands-on. Good luck — sounds like a lovely project!

I know this post a bit old but we did something similar on a rural renovation project — open book with a % fee (ours was 14%) and a shared savings model. Honestly, it worked pretty well, but only because we had good visibility and stayed closely involved. The big upside was flexibility and transparency (helped us avoid feeling ripped off), but yes, it requires trust and time to manage. We also capped the total cost to avoid things spiraling. Your idea of sharing savings with the builder sounds fair and could help align incentives. Just make sure you define the terms clearly upfront.

We had a similar situation with a local builder for a rear extension last year, and I remember how stressful it was trying to balance protecting ourselves without upsetting the guy doing the actual work. What helped us was tying each payment to visible progress, like payment after groundwork, after the shell was up, etc. even if we didn’t have an exact breakdown. It gave us some reassurance without making it feel like we didn’t trust him. We also asked for a simple schedule in writing, just bullet points, to keep everyone on the same page. Hopefully this helps a bit 🙂

Not an expert either, but I actually tackled something pretty similar for a retaining wall along my sloped garden path. Your idea sounds totally reasonable. I did almost the same thing with stepped footings to keep the block height level across a slope. In my case, I poured the footing in sections using formwork that followed the slope, but made sure the top edge of the blocks stayed level. It took a bit more time to measure and plan, but it made everything look so much cleaner in the end. One thing I learned the hard way: make absolutely sure your footing is solid and wide enough, especially toward the downhill side. Mine started to shift ever so slightly after heavy rain because I underestimated drainage. Also, if you're doing the pour in sections, make sure to key the footing joins together somehow so you don’t get cracks later. I’d also recommend checking the slope with a string line or laser level before you start pouring — saves a lot of second guessing once you start laying blocks.

Hey Harman, interesting topic. I actually went back and forth on this during our last renovation. We didnt hire a full-service interior designer, mostly because of budget, but we did feel the need for some guidance. I think a lot of people in the selfbuild space are somewhere in the middle, they want their space to look thoughtful and cohesive but either can’t afford a designer or don’t know how to justify the cost. Personally, I would’ve been more likely to hire someone if they offered flexible, modular help, like just layout planning or finish selections.
