So, the builder is coming on Monday and I thought I'd made a decision but I'm having second thoughts.
We currently have a 1950s built house with separate loo and room with sink and bath. The upstairs of the house is badly laid out with a lot of wasted space but unfortunately not in the right place to be able to utilise it for the bathroom.
We have the doors to the loo, bathroom and master bedroom forming a U shape (door frames butting each other), the toilet door opens outwards onto landing and I'm worried about knocking someone out on my way out and can't be re-hinged as there's not enough room to open it into. It's just all a bit cramped. (Hard to explain)
My thought was to take one of the doors out of the equation (the toilet door) by creating this L shape. But... the resulting space leaves us with only one layout option and not much more room to move.
We have two DDs (5yo & 9mo). So, do we just refit the two rooms adding a sink and (much needed heater) to the toilet, choosing more space efficient fittings, or, do we knock the wall down? 
It's not our forever house, and we've lived with it for > 6 years, so I guess I'm asking (partly) which is the more sale-able option (though I doubt we'd move for at least another 4 yrs).
Any other suggestions welcome, though we're not made of money! 
thanks
