In our new-build bungalow, we recently had our loft boarded and the hatch extended, so this is spare - virtually unused.
It would fit an opening which is 720mm x 552mm, and has an outer overlap of about 62mm all round. It opens by sliding it forward a bit then it hinges downwards. The door can be removed for fitting the frame. It has an insulation sheet of about 50mm thick built in. It was in our brand new bungalow, so should meet current insulation regulations.
You'd need to collect it in person from the Cirencester (GL7) area.
