Hi All,
I'm planning to build a summer house at the end of my garden up to the boundary, with rough dimensions of 7.5m x 3.5m, flat warm roof. Plan to use the space all year round as an office though will also house gym equipment and therefore am looking to maximise the head height for over head lifts whilst staying under the 2.5m roof height. Preferring a warm roof to allow space for lighting, loudspeakers etc.
Given the close proximity to the boundary I understand I need to build from "mainly non-combustible materials" so have resided to a proper build with blockwork, trench foundations etc. Given I will be lifting weights in the space I've assumed i'll need a decent concrete floor base also.
I plan to set the building slightly into a small upslope which starts around 1m from the end of our garden and has been created through years of people dumping waste from their allotments onto ours which was completely overgrown and unused for some years. A couple of dead oak trees some 10m beyond the boundary have also pushed the ground up around and towards the boundary which we'll level off to gain some extra height.
The rear wall against the higher ground will extend beyond the summer house at low level to create a small retaining wall which we'll put a fence on top of which will extend to the neighbouring boundaries. The land being retained will be very little given the general land height around is lower, its just the general build up around the rear of the property which we would like to take advantage of to gain some extra internal height.
Queries:
- Will the attached detail provide the required level of waterproofing given the finished floor is below ground level which I understand should generally be avoided?
- Will the proposed floor design support the impact of dropped weights (~150kg bar bell) with rubber matting on top or should I consider something else? I was trying to avoid insulation beneath the slab as I understand this takes longer to heat up or is it really not that different?
Thank you in advance for your responses.
