We wanted a whole wall of cupboards in Bedroom 3 as storage, and to blend-in the enormous water tank that now resides in there.
The first job was to get in some datum uprights to take other measurements from. It took a while because there's no straight-lines in the Cottage - nothing is parallel and there had to be some 'by eye' judgements to line things up with either floor or ceiling, wall or floorboards.
The next job was to clean up and replace the area of ceiling above the cupboards, but allow access to the complicated water tank system which is now up there. I decided that installing a large hatch would be easiest in the long-term.
Removing the old insulation, cleaning the access areas and insulating the tanks took half a day, and I put back in new insulation in all of the areas except for directly under the cold-feed to the tank, in an effort to use some heat from the house to stop it freezing in winter.
The hatch is held up on a set of wedges which will be blended in to the black oak beams, and a pulley system which is hidden in one of the cupboards. The idea being that in the event of a leak or needing access to the roof it is quick and easy.
A simple set of pulleys make sure the hatch is up and snug with the ceiling.
