block work

Hi, I am planning on building some raised beds around a patio using blockwork and then fitting porcelain cladding. The beds will be about 4m by 1m and about 0.6m high. To keep the costs down I was looking to use a single skin of 100mm wide blocks, would this be enough? Or should I use 140mm...

Morning all,lintel help please,have asked the question before,but tomorrow I will be installing lintel 'hopefully' I understand the lintel needs to sit on full blocks if possible to support the 3900 IG lintel (flat roof single single ext) From my photos the external block work would be sitting...
