Sorry this is long! We have just spent 2yrs doing this OP, so happy to answer any questions you have. Derelict property that needed new roof, 2 walls taking down, steels put in, new floor boards/joists, retrofitted insulation, underfloor heating, 38 new windows and 2 large bifolds, complete new kitchen and bathrooms and a 3x4m extension etc. I wrongly assumed it would take 1yr, it took 2 and we are only just in the house. Structural work done- but lots of bits to finish still.
Just DH and myself and we bought a static van. Ours is a small 2 bed, 28 x 10, but if you can- get the largest you can fit on your site. Ours was positioned right over the sewer, so it was very easy to plumb it in for a flushable loo. DH and I both WFH- which was challenging at times in a van- but certainly do able.
Our van is single glazed with a gas fire. You can get 'winter ready' vans with double glazing and central heating- but the costs really go up to buy these- but equally, resale value might be more. An electric blanket and a karcher window cleaner- to remove the condensation in the winter were life savers.
We had things sealed in crates and those vacuum bags in the house- and despite being in closed rooms- dust got in everywhere. For the noise and dust alone- having somewhere clean and separate from the worksite was lovely to escape to. I'm SO glad we didn't decide to try to live in the house whilst work was going on.
1 thing we didn't have was a washing machine. If you can put one in a shed or a room in the house- it will save a fortunate and time in going to the laundrette.
Think about parking for trades. We have a very large area at the front- which could fit maybe 6 cars. Many trades have large vans though, and some days we'd have 6 or even 8 people on site- so parking can be an issue.
Provide solid bins ALL over the garden and in the house. I found lunch wrappers, cans, cigarette packets etc hidden/shoved inside pipes, pots and all around the garden! 😡
Speak to the council, because you should get a year off paying the council tax if the house is uninhabitable. If the house has been empty, ask the council for their empty homes inspector to come and assess it. Empty 2-10yrs, you pay only 5% VAT on materials to get it back to a home. Empty 10yrs+, you pay no VAT on certain materials!
IF you set up a drink station with a cheap kettle, tea, coffee etc- get cubed sugar because it won't spill all over the place and attract ants!
We are in the process of selling our van- so let me know if you want a little one 😉
