The house has 29 doors assuming the double doors count as 2 rather than one doorway.

Cars have 12 doors, two 5 door sedans as tailgates are now called doors and one MGB with two doors as the boot is not counted a door.

Cars have 14 wheels as both sedans have a spare wheel.

4 bicycles make 8 wheels.

Two wheel barrows, 2 wheeled trolley and two skate boards mainly used for moving stuff adds up to another 12 wheels.

So the doors win even without counting kitchen cupboards etc. as doors. But I guess the doors in the bedroom built in cupboard should count and 3 bedrooms have 4 doors each making it another 12.

OK so does this mean I need more cars, or maybe pushbikes because they don't add to the door count.
