Minor set-backs my friend! Seriously, I'm sure half of us have had that 'wtf did I start this for' feeling when waking in the small hours soaked in sweat and dreaming of -insert current snag here -. It's hard to keep perspective when it's your life/money/sanity, but it will be worth it when it's finished and the PTSD subsides 🙂
Plus plot clearance and any additional costs associated with a brownfield site. Assuming the key requirement of a reinstatement cost is for insurance purposes, I wouldn’t want to estimate on the low side. It might not make a huge difference to costs as policies tend to have an 'up to' limit in quite broad brackets. I know for sure that if I had to rebuild my place I would not be hands-on again, so insurance would need to cover a builder and their profit margin.
Bespoke, so they can build what you want. About 18 months ago, the frame was just under £19k erected, and included timber for studs, joists and cladding, but it is quite big: effectively 3 bays plus wood store each end, and storage space up top. Still progressing at a snail's pace as a 'spare time job', but looks more like this now...
Have a look at profilestore.co.uk, ventilation profiles. They do flat or angled in black at good prices. I bought some recently for proofing some cladding.
Nah...looks off to me too. More like an a 'artist's impression', particularly as one of the kitchen above-counter sockets appears double-up through the photo montage...
That's the only one of three that made decent progress, and that's still probably the case 3 years on tbh. I did make an early mistake of using garden soil for some planting, so maybe a nutrient overdose.
At risk of going off-topic... then there's the upfront cost for a minimum delivery (500 litres?) to consider. I don't use oil, but I can see why people find themselves having to live in a cold house for a while.
