Renovated an old house in Brittany when my husband was over 70...he LOVED working all day (and most of the night !) I insisted we had certified and registered artisans for electrics, a new roof and a new boiler, but otherwise he tiled all around the garden, borrowed a tractor to dig up the veggie patch and lay lawns 1 built patio and fountain at the bottom of the garden...paved all round the house, built a 'coffee corner' to resemble the one he built when we had a new villa which he built, in Menorca some years earlier ...in that, he couldn't wait for the Spanish workmen so he even did some electrics in that one ! tiled all round the pool, built frames for grapes all round it .....never stopped ! I painted all the inside and did whatever I could but now I am at the age he was then and there is no way I could do all that !!!! you will Enjoy it, but make sure it is not all work and no play !
