Noka Lodge in the Lapalala Reserve, South Africa, is a joyful echo of the muted rust and jade green of the aloes, euphorbias and succulents clinging to the rocks along the cliff face in all the tones of baked red, saffron yellow and muted green. Walls disappear through the use of huge glass panes and each vista becomes a framed work of art on a grand scale. Noka is suspended on this edge, quietly guarding the view of the river.
