The church was raised in a neoclassical style typical of its period, with a timber frame and cladding of horizontal boarding on a rendered, grey-painted base. A vicarage on the neighbouring plot, designed by architect Sven Tingström, was built at the same time and deliberately kept in keeping with Ericson's overall scheme, as was a later parish wing added in 1962.
Inside, the church retains much of its original character. The ceiling vault was painted white, with no visible light fittings; instead the room was lit indirectly by a great number of small electric lamps concealed behind the deep eaves. Painted decoration on the walls, together with the font and pulpit, were the work of sculptor Johan Björck and the artists Fritiof Svensson and Joel Mattson (also known as Joël Mila). The timber font and octagonal pulpit, both designed by Ericson, are marbled in shades of pink, black and green with gilded, red and white detailing.
The building has seen several changes over the decades. In 1956 the architect Johannes Olivegren designed new wall lamps, since replaced, and a stained-glass window near the pulpit is thought to date from around this period, though its origin is not fully certain. A more substantial interior rebuilding took place in 1965–1966, when a new mechanical organ with a Rückpositiv division was installed in the gallery front, built by the Lindegren organ workshop; a further restoration followed in 1999–2000. In 1982 the semicircular entrance steps were remodelled to improve access, with a sloping path added alongside the original stair.
Although long known simply as a chapel, the building officially took the name Brämaregårdens kyrka in June 2001, a change intended to reflect its standing as a consecrated church rather than a subordinate chapel.
