yeah my m8 is a plumber which helps.
iv used to work with a building firm for a couple of yrs but it was a long time ago now. iv had a couple of houses iv done up as has my m8.
i reckon we ok for digging out and footings, concreting is easy as i screed, brickwork would get a bricky, windows we can do, and i no how windows should be done as it does my nut in how poorly most people fit them before we plaster to them, chippy for roof and 1st floors, sparks for sparks stuff, we can then plaster, paint, cove, plumb, doorlinings, architraves and skirtings, insulate, lay floor/patios, tile, m8 does kitchens and bathrooms, so im hoping it would go alright. the only thing iv never done is outside drainage
