We have a patio area we would like redone and extended with porcelain tiles we have seen. We would like drainage out in with those metal grate things. We would also like two areas of composite decking laid, one at the same level as the patio and one raised. The raised one would have a area cut out in the middle for a flower bed. We have a raised bed which we would like to have rendered (not sure if you do this) and then there is a step to cover with new porcelain tiles. Over all there is about 13.5 square metres of decking and 31 square metres of patio. This is rough my accurate as my calculations might be a little off!
