Two sheds in one, right hand bit (accessed on side) for garden stuff - lawn mower,barbeque, furniture, etc. Left hand bit for office (accessed at front) with computer (hard-wired internet), fridge, sink (hot & cold water), underfloor heating. But made to look symmetrical to match the symmetry of the main house
Traditionally built (insulated cavity wall structure) floor joists (insulated in-between) in materials to match house (red soft brick, wooden door/window frames/fascia). Light-on-ground structure with foundations bridged over tree roots. Finished floor level same as main house and lawn to further add to harmony within relatively small garden space
