I have a 1960s house and below is an area of my loft I want to board it's about 1750mm x 1650mm. The joist to the rear you can see is about 5" the same size runs through the centre of the loft. Presume there is another of the same thickness on the other side of the loft.
My question is, how do I board this area presume I need a frame, the smaller timbers you can see below the joists are about 75mm batons to hold the ceiling up I presume. Any help would be appreciated.
