Would you be interested in building me a shed? I am after a couple keen quotes but then pretty much ready to go (area already cleared in readiness). The project doesnt require planning permission (as will be 2.4m in height) and I have already have gone through the Certificate of Authority process so should be ready in a week or two to go ahead - if this works with you.

If you are interested give me your email and I will send over the plan of proposed shed.

Sizes: Main rectangle (3m x 5m) plus higher level storage part on right (1m x 4m).

Usage: starting as storage area then become a tool/handy making area with relaxing space (need insulation so can be used year round).

What type of shed?

Base concrete then dpm. Will need good sound/heat insulation plus lighting/power and water provision (even could be as basic as a hose). We will supply a basic mini kitchen.

Floor - treated timber 125mm x 47mm (C16) (undergone a chemical treatment to prevent fungal attack and rot) using angle brackets
to screw joists to the concrete blocks.

50mm Celotex board insulation. Breathable membrane paper sandwiched between. Tongue and grove plywood 18mm sprayed with high quality timber preservative. Laying techni boards over that.

Stud walls: Thinking timber 47mm x 100mm.(C24) doubled up where the doors go. 50mm Celotex board insulation.Breathable membrane paper.

Internal walls: Green plasterboards, Plastering and Painting.

External construction/Insulation - currently thinking about using hardwearing plastic (fascia look a like wood design) in either overlap or v section to reduce future maintenance/damp/mould.

For cladding/like wood fascia currently thinking: Eurocell cladding/shiplap-cladding/shiplap-cladding-oak-on-white-x-5m.

Thinking about the wall construction - using 44mm x 69mm hardwood, the cavity filled with 50mm foil backed insulation celotex board. Internally the walls lined with 9mm painted MDF.

We already have the x2 mahogany bi-fold doors (due to their weight a solid skeleton is needed).

Roof: Sprayed fibreglass. Treated timber 125mm x 47mm (C16), green plasterboards and 50mm Celotex. Base to fibreglass - 18mm OSB3 Boards.
Two 1m x 1m roof windows (need to source).

Windows & doors
- Re-using existing garden room x3 narrow double glazed horizontal windows (non-opening) and x2 box windows either side (right hand side upper section and above w/c on left).
- Bi-fold doors already supplied (on site).

Internal design - one large room/space with small rectangular higher level to store tools.

Surface water/guttering - The roof slopes downwards (to the right) as shown in design attached. So UPVC guttering is required along the whole of the right hand side. The down pipe potentially located at the back of the right hand side with a water butt underneath. The aim is to reduce all potential puddling/surface water.

Both water and electrics to be supplied via the house during the works. If necessary a new supply can be taken from the consumer unit within house.

Hope this give you a bit of an overview!

If this is of interest, please send me a couple examples of your work and connect with me. Thanks.
