I need advice on digging and shuttering, and then a professional to lay some concrete for a sectional garage
convert garage and outbuildings to annex; refurbish main house inside and out
current structure is brick built single skin, with pitched/tiled roof with window to side passage. Base: concrete about 4" (by eye), Metal Garage up & over double door. Want to convert to indoor workshop/studio, so insulating all round (walls, floor, ceiling), plastering, fit hatch to garage loft space and wld like stairs to loft rather than loft ladder but poss beam supporting loft floor will make access difficult. Floor finish; thinking of tiles. Fit new half glazed bi-fold doors to replace existing garage door. Also make & fit wall racking to carry stained glass stock and tools. Plumber (for sink area & heating) & electrician arranged.
