I need to invent a way of raising a heavy german washer and dryer up from the floor so they can be used without stooping (elderly persons). Say by 400 mm. The floor is supended and I imagined creating a raised floor /joists/bolts/studs and resin etc. just big enough for the appliances. However, also seen this week, similar appliances elvated in what looks like a normal kitchen cabinet - think built in oven cabinet, but appliance lower. There was a cupboard under each, with a pull down door. Any idea how such a cabinet is made? You might think an out of balance load would shake the woodwork to bits!
