I'm not sure when, but it was well before 1983, because that was the year my my father-in-law died. He had been there a few years earlier, helping us with a spot of decorating, and had cleaned paintbrushes in the sparkling new stainless steel sink - leaving spots and smears of paint on it!
My DH had installed the new kitchen, removing old tiles, replastering, rewiring, changing plumbing so that the sink could go in a different place, fixing new tiles, decorating - the whole job. I was in my normal status as chief sidekick, tool finder and cleaner-upper. It took a while to complete. At the time we had two children in primary school and one at secondary, with all the cooking and washing that entails.
We had planned the positioning of everything ourselves and ended up with exactly what we wanted, where we wanted it. It is still pretty good and will last me out. Sometime I shall revarnish the solid wood doors as the edges are a bit worn, but the rest is fine. We chose simple pale maple units and doors which weren't the then popular dark oak with heavy figuring, so it hasn't gone out of fashion.
