The blocks containing the ancillary rooms project through the fully glazed gable walls. At one end the entrance area with organ and choir gallery, at the other the vestry and the rear wall of the altar dais; the transept contains the confessional and baptistry. The altar dais is identified and highlighted by a raised glass cupola in the roof.

The naturalness and simplicity of the design and the materials used contribute to turning the church - like the whole complex - into a calm focal point, both inside and outside. The external spaces and changing natural lighting effects play a major role in determining the overall effect of the inside of the church, underlined and enhanced by the artistically designed areas of glazing.

Structure | Braced roof trusses at a spacing of 3 m form the principal structural element. Struts at different angles support the main rafters at three positions. They are supported at a point 2.50 m from the external walls, i.e. within the church itself, the lowest strut rising almost vertically, the second supporting the main rafter at the two-thirds point and the upper one emerging out of this to carry the ridge. Struts and main rafter are all 160 x 240 mm. The lower section of the rafter is propped by a 160 x 200 mm post positioned directly in front of the external wall, forming a sort of jamb-wall effect. All joints are stiffened by 80 x 200 mm ties. The ties at the support points for the main rafter also support the purlins which in turn carry the secondary rafters for the roof covering itself. Purlins are 160 x 260 mm, rafters 160 x 140 mm. These rafters are spaced at 50 cm centres and carry the ventilated cold roof construction comprising 11 mm boarding and 80 mm thermal insulation. The roof loads are transmitted via the struts and posts to 300-mm-high masonry plinths supported on the foundations. Actually, the masonry itself is non-loadbearing, the loads being carried by built-in steel sections which can accommodate the horizontal thrust. The whole design is braced within the roof construction by the roof truss which resembles a timber framework. Three-dimensional stability is achieved through the intersection of the two pitched roofs in the centre of the church. All timber elements are made from glulam beams employing a resorcinol-based adhesive. Most of the timber-to-timber joints are bevelled shoulders or rebated in the traditional carpentry style.

The glass wall is joined to the truss ties at 500 mm centres by means of galvanized steel sections and only sealed against the underside of the roof boarding. Therefore, the window transoms form the principal loadbearing elements in the window design.
