a 1 in 40 drop is 25mm drop in a 1 metre run. To measure that, I have a standard 1 metre long level, and I tape a small bit of 2*1 timber to one end of the level, then set the pipe so the level reads level and you have a 1 in 40 fall. You won't get any droops or puddling at that fall. You can go to 1 in 80 if you are short on fall. Then you have to be more particular that you can't get droops in the pipe run.

No, the theory was you wouldn't be able to access the rooms to get the screed in

I did look at getting a caravan but most I saw were pretty crap and certainly insecure if you wanted to part use them as storage. In the end I'm getting a 50/50 office/storage container for 25+vat/week - decent space for the guys and secure storage for some gear. Delivery is 125 each way

We used a horrible small broken down old caravan that we won for something like £180 locally on ebay. The deal was similar to yours @Grosey - it had to be delivered (this thing seriously didn't look like it would make it!) We had it onsite over winter and it was great, actually. It was so small and flimsy that a small column heater would get it quite comfortable within an hour even on a cold day. It was falling apart so we didn't fuss about the inevitable knocks and filth due to muddy-booted builders coming and going. Once we had windows and doors in the house, we were able to move inside and stop using the caravan. In the end, we had to chop it up and get rid of it, which I think cost another £100. Still not a bad deal overall. Given the way builders tend to treat these things, I'd be reticent to assume it'll be good for anything but scrap once you've finished with it, so factor that into your sums. Re: a portaloo, having to regularly empty a chemical toilet used by builders is a false economy in my opinion. I'm not squeamish but I had better things to do onsite than deal with this every other day. I'd pay the fee to get one onsite, serviced weekly, and use the time not spent emptying it to do something more productive.

This is a couple of steps I made with the same home made router jig as the full set I scrapped. Each tread set in about 1/2" and the stringers through housed. Then 6mm screws in from the sides with glue: One option I did consider was say a 9"x3" as a single, central "stringer" then thick treads set into that.

Here's my "scaffold stairs" that are serving me at the moment. I think part of the reason for me not wanting to fit a temporary set of real stairs, is mine will have a half landing and return, so it's a lot more complicated than just bang in a cheap set of mdf stairs. But here is what you can make cheaply. These are my garage stairs in my present house. the upstairs of the garage is technically only a storage platform so these are not meant to comply with regulations. they are in effect a permanent ladder. they are made from leftover bits of 8 by 2, and (you can tell I am not a joiner) each tread is just fixed to the stringer with three 6" nails.
