We live in a small standard Victorian terrace in London with a small front courtyard/patio in concrete slabs. All the concrete is coming apart / keeps filling up with weeds so we want to tear it up and redo with grey rectangular outdoor porcelain tiles. Has anyone done this and have any recommendations? All the rectangular outdoor tiles I’ve found at all the usual places (topps b&q etc) are min 90x60cm which our builder says are way too big for such a small area.. hoping someone might have some ideas!
