The church was declared redundant in 1965 and now forms eight flats as St Martin's Court.

An earlier, temporary mission room of St Martin had been established facing the nearby recreation ground, but was soon inadequate to serve the parish.

[1] The plans for the church were drawn up by Charles Edwin Ponting of Marlborough and Messrs Jesty and Baker of Portland were hired as the builders, with Mr. D. Grant acting as clerk of the works.

[7] St Martin's is built of Fordingbridge red brick with Portland stone dressings in the Decorated style.

The church had to be built on deep concrete foundations owing to the sloping ground and soft subsoil.

Part of the intended crypt was completed in the work of 1907–08, which was to form a larger parish room but was instead used as a vestry.

The porch has a large three-light traceried window above and flanking buttresses rising up to the roof.
