I’m thinking about putting a building in the corner of the garden as a home gym. I like exercise and I would use it (as opposed to commercial gyms which I don’t and won’t). The options for the building itself are enormous, from the humble shed with internal insulation and a bit of cladding through to deluxe factory produced designer efforts better suited to Grand Designs. Any experience here of getting a suitable building installed (the contents are irrelevant really – studio, office etc)?
