Calvary Charismatic Baptist Church (formerly Trinity Methodist Church), including attached hall, church rooms, residential accommodation and walls

Calvary Charismatic Baptist Church, including attached hall, church rooms, residential accommodation, and boundary walls.

Built as Trinity Congregational Church between 1949 and 1951, designed by Cecil Handisyde and D Rogers Stark with engineer Felix Samuely. The building was restored by Edward Mills in 1976 when converted to a Methodist church. Further residential accommodation was added to the Annabel Close side of the site in 1980 by John Brunton & Partners.

The structure uses a reinforced-concrete frame with concrete panels, varied stock brick, copper wall sheeting, and an aluminium cupola to the tower. External cloisters have terrazzo flooring and the entrance area is tiled. The chancel floor and steps are polished Hopton Wood stone.

The roughly square site is planned as a three-sided complex of buildings around a central courtyard opening to Annabel Close on the east. The church itself is a tall galleried space attached on its north-west side to a two-storey church club room range that runs across the site and connects to a double-height hall positioned parallel with the church across the open courtyard. The church occupies the south-eastern corner, set back from East India Dock Road. A recessed entrance block and bell tower mark the south-west corner with a small sunken garden in front. Residential flats occupy the two-storey building at the north-east corner, with a boiler room beneath.

The main church building is dominated by an angular portal frame from which the roof is suspended. The east and west end walls are clad in dark precast concrete panels using crushed London stock brick aggregate. The angled north and south walls incline inward and are clad in copper sheets with chevron joins. Above the side walls runs a continuous band of clerestory windows. Both sides have ground-floor colonnades of thin pilotis. A lower brick chancel sits to the east with a series of angled, narrow windows at upper level. The exterior brickwork on the east elevation mixes regular and dark stocks, with darker bricks as headers in a bond of two stretchers to one header per course, creating slight overall texture. To the west of the church is a recessed two-storey glazed entrance and staircase area. The rectangular brick tower at the south-west corner is crowned by a delicate open octagonal cupola with slender aluminium supports to a circular top with top-lights and finial. The return wing is two storeys with metal-framed strip windows. The George Green Memorial Hall has a similar suspended concrete roof to the church, though with metal-framed glazing flush with the portal frame and a recessed clerestory set above. A blind brick elevation to the footpath marks the north side of the site, with a band of clerestory windows set back behind the portal frame. Windows throughout are metal-framed casements; most internal doors are original with ply fronts or part-glazed with thin batons separating the lights. The residential accommodation to the west is stock brick with metal-framed windows, those to the first floor along with the inset central entrance set into projecting concrete frames. The southernmost bay of the eastern range is a later stock brick addition built to match, formed as part of the 1980 extension and reconfiguration.

The main body of the church has a gallery to three sides set above a compact ground floor. Daylighting comes mainly from small dome-lights set into the suspended roof. High-level clerestory windows to both north and south walls prevent glare from the roof lights. Lighting for the upper level also comes from a series of angled windows on either side of the chancel, mostly invisible to the congregation but focusing attention on the east end. The angled chancel windows on the south side are amber coloured to give a warm effect and reduce glare. Smaller side windows at ground-floor level are below the gallery; those on the south side facing East India Dock Road are double glazed. An etched window from the old Trinity Church has been incorporated into the north side, designed by A L Moore & Son of Southampton Row and dedicated to the memory of H T and G E Nye, both killed in the First World War. The chancel floor and steps are polished Hopton Wood stone. Original fittings include a flared decagonal pulpit, flush-panelled balcony fronts, moulded plywood pews in the gallery, and pendant light fittings each with a bowl and five down-lighters in a distinctive Festival of Britain manner. Interior walls at ground-floor level are fair-faced sand-lime bricks. Concrete walls above gallery level are lined with hardboard on timber battens, with glass fibre infilling to improve thermal insulation and sound absorption. Several hardboard panels to the west wall are perforated and arranged in a chequerboard pattern. A sound control booth has been added to the south-west corner of the gallery.

The main entrance area from East India Dock Road is a light double-height space giving access to the church body, rear club room wing, and gallery level via a concrete staircase with steel balusters to the west end. The bell tower has its own entrance from the small garden and a steel ladder giving access to the belfry and roof. The bell is from the original church, salvaged from the rubble of the destroyed Trinity Congregational Church in 1944. The club room range has a central corridor with a small church hall and kitchen to the east and a series of club rooms (now used as a nursery) to the west side, all simply furnished. The rear main hall has a raised western stage with projecting surround, lit by clerestory windows to the north and south walls and three sets of original double doors to the south. The residential flats to the upper level of the club room range and those created through the 1980 reconfiguration were not inspected.

Stock brick walls with concrete capping slabs and steel railings mark the plot boundary to East India Dock Road and Annabel Close. The gates to the courtyard at Annabel Close are later replacements, though those to the small courtyard area at East India Dock Road are original.
