Hello, I would appreciate any advice on the following:
I want to have a side-opening velux window fitted in my loft, to use a large telescope weighing 70kg.
To support the weight of the telescope I think I would need to have joists added on load bearing walls.
Could the joists be added for a specific width to accommodate the telescope, approx 1 metre, or would the whole loft need to be done?
Thanks
