Where to start!
Levels were messed up so including the odd step, all floors slope significantly and I spotted in old planning drawings that they had miscalculated the levels to the tune of circa +150mm across the ground floor. Bathroom is 1.4m wide with a bath taking up 0.7m of that so you have to open the door, squeeze up against basin, close the door to access the WC. Weird eaves detail which is great for ventilation and vermin access. Internal balcony made out of an old pulpit to give almost an open loft access / weird space off the main bedroom accessed by a spiral staircase from the middle of the bedroom. All windows understandably rotten as single glazed softwood throughout. The site has great uninterrupted views of the sea so the only window on that elevation is a 600 x 600 bathroom window. Foul drains run from garage / utility type situation under the 'new' build part of the conversion, with rodding eyes / inspection covers in the concrete floor of the internals, despite there being a big site and plenty of soakaways and septic tank availability. Everywhere is so dark that internal lights required on all but brightest days. Bed 2 has a back door which makes it more use as a hallway. It's honestly so weird.
It seems that the National Trust were even more skint in the 80's so were happy to let any one take on old crumbling barns and convert them to minimal standards and as cheaply as possible, to get the asset liability off their books.
On the positive, the site is large and plenty of working space, and no significant damp. Dont get me wrong, we are so grateful, but wow this sometimes feels like a poison chalice. Doing everything (new build & refurb) is just not affordable to us without significant borrowing so plan is to build new alongside, join up, move in, then refurb remainder over time.
