Hi I've just purchased an observatory dome and I'm in the process of putting it all together. I'm thinking of putting 45mm foil insulation in the walls. I've been advised to use vapour control and breathable membrane. So the layout will be as follows: interior walls are marine ply then vapour control sheet then stud timber frame filled with the 45mm insulation. Osb board on exterior wall with batons fitted and pvc cladding. What I need advice on is I have got damp proof membrane under the slabs I'm putting the observatory on. So I have the soil then the damp proof membrane sheet then sand cement mix and then the slabs. Will I need to vapour control the observatory floor? Any help would be very much appreciated thank you.

Hi I just wondered if anyone uses a small plastic shed as a bit of an office whilst doing astro photography. I wouldn't feel comfortable leaving £3000 of equipment that I have just purchased outdoors without being close. I've not long got over cancer so have to be extra careful during the winter with the freezing cold. Ive looked at observatories but they are out my price range. I've tried to pick up a cheap second hand one but not having no luck at present. So I'm thinking about a small plastic shed just to be able to put a laptop stand and chair in. I will not be leaving equipment in over night but just need a bit of shelter and base for laptop and cases whilst outside. Also an access point for power supply. Any advice would be appreciated thank you
