Aisled nave with clerestory, N and S transepts, chancel with vestry to N and organ loft to S and W tower with octagonal stone spire. Externally the rubble tower and its ashlar spire, with two tiers of dormers, are clearly 14thc. Everything else looks 19thc. In fact the N arcade and the chancel are 14thc. too, but heavily restored. Construction is of coursed ashlar, much of it irregular. The only 12thc. features are sections of string course neatly reset inside the S porch.

A sawtooth string course survives at Haslingfield, and fragments of one at Great Shelford. Here at Stretham we have string courses carved with three different motifs, suggesting that the 12thc. church was a building of some pretension.
