The church retains a medieval tower, but the rest was rebuilt in 1824-24 under the supervision of architect
Andrew Patey of Exeter. The church re-opened on 1 May 1825. In 1851 a daughter church
St Mark's Church, Dawlish was opened in the town. Despite the later addition of galleries, the accommodation at St Gregory's was inadequate for a growing population, so the church closed for 18 months at the end of 1873 for enlargement. The transepts were enlarged and a chancel was erected long by wide with an aisle on the southern side of it. An organ chamber was added and a vestry on the northern side. The architect for these alterations was
James Piers St Aubyn and the contractors were Diment and Stevens of Bristol. The cost of these alterations was in the region of £6,000 (). ==Organ==
