I need to build some concrete foundations for a 7ft x 7ft play house however my back garden is on an upward angle of approx 20 degrees. What is the best way to do this?

Thanks

I ASSUME THIS FOUNDATION IS FOR A TIMBER PLAY HOUSE!

IF SO,

CONCRETE BLOCK PILLARS SET LEVEL IN FOUNDATION PITS AT CORNERS AND SIDES TO COINSIDE WITH THE TIMBER JOISTS OF PLAYHOUSE FLOOR JOISTS.

OR

DIG OUT TO FIRM SUBSOIL, A LEVEL TERRACE IN THE SLOPE OF THE GARDEN AND LAY A CONCRETE RAFT FOUNDATION ON WHICH TO SIT THE PLAYHOUSE.
A SMALL RETAINING WALL MAY BE REQUIRED AT HEAD OF RAFT TO SUPPORT SOIL FURTHER UP SLOPE.

CHEERS,

ALDA.

Into the slope and a retaining wall to hold it back.
