Above this diffused light enters through a rose window of stained glass. This is flanked by further lights on the lower level, while twin organ pipes emphasise the symmetry of the pulpit. The building is constructed of Oamaru stone, set on foundations of basalt breccia from Port Chalmers, with details carved by Louis Godfrey, who also did much of the woodcarving in the interior. The use of "cathedral glass", coloured but unfigured glass pending the donation of a pictorial window for the rose window is characteristic of Otago's 19th-century churches, where donors were relatively few reflecting the generally "low church" sentiments of the place. Similar examples can be found in Lawson's churches throughout Otago. Notable among these are the former Trinity Methodist Church in Stuart Street, Dunedin (later used as a home for the Fortune Theatre), the spired Knox Church in the north of the city, and the Tokomairiro Presbyterian Church in Milton, said at the time of its construction to have been the southernmost building of its height. Lawson also designed Knox Church, which has a similar tower, also in Dunedin. This building, less well known than First Church, also designed in the 13th-century Gothic style, but in bluestone, is considered by some to be his finest achievement. Larnach Castle 1871 Lawson designed several large private houses, the best known was at first called "The Camp". Today it is better remembered as Larnach Castle. It was built in 1871 for William Larnach, a local businessman and politician recalled for his bravura personal style. It has been hailed as one of New Zealand's finest mansions, described on its completion as: "doubtless the most princely, as it is the most substantial and elegant residence in New Zealand". There is a tradition that Larnach designed his house after Castle Forbes, his father's house at Baroona in Australia. The plans, however, are unquestionably from Lawson's office. The origin of the myth is simply that Larnach Castle has verandahs, doubtless insisted on by Larnach, an obviously colonial addition to its otherwise conventional revivalist design. However these do lend it distinction. Although some have questioned if Larnach Castle was an essay in the revived Scottish baronial manner. The main facade resembles a small, castellated tower house, with the characteristic rubble masonry, turrets and battlements, present at Abbotsford, an exemplar of the style. It has been accurately described as a "castellated villa wrapped in a two-storey
