We used to own a detached house which cost less than our UK 3 bed bog standard semi with one parking space. It had the following:
Double integral garage with remote doors. Proper big enough to drive a pick up truck and a 7 seater in together with loads of storage space for tools, workbench and room for DC to chase each other around the cars.
A kitchen with an island and a walk in pantry.
Central vac system as described by a PP. No carting a hoover around.
Heating/air con system that blows air out of a grate so no radiators. Lovely and warm in winter, cool air in summer.
Central water softener and filter.
Massive entry hallway with cupboards each side for coats and shoes.
His and hers sinks in en-suite with two person shower.
Walk in wardrobes in every room. Ours was the size of smallest bedroom of the house we had in the UK.
A full basement with windows and underfloor heating. A reception room half the size of the footprint of the house together with a playroom/library, gym room, shower room, and a laundry room.
A furnace room where we could put clothes not suitable for the tumbler on a drying rack. Again the size of a small bedroom.
Half an acre of land.
That was a pretty typical house in the area where we were (a town an hour outside a city in Canada). I honestly want to cry that we came back! I want that house back <wails>.
