stands as a recent commission by Green Oak Architecture. The ‘cross wing’ in
the foreground, part of a significant new extension, merges with a rear single-story
segment. Mimicking the existing oak frame with its rendered infill, the one
exception lies in addressing its thermal shortcomings. The original frame
featured exposed internal and external frames, leading to poor weather, air
tightness, and cold bridging issues.
Collaborating with the clients, a dual-frame approach was adopted. The internal frame, carrying insulation, serves as the structural core, while the external ‘cladding frame’ supports the render panels. The latter employs air-dried oak sections for stability. Behind it, a vented cavity, Moisture Control Membrane, and insulation combine to ensure a high-performance envelope. The kitchen’s rear extension, doubling its size, employs a ‘direct glazing’ system and a Juliette balcony for the master bedroom, enhancing views and ambience. The flat-roofed section preserves upstairs vistas.
Matching the heavily beamed ceilings of the original structure, the extension, constructed in 1991, maintains symmetry with pairs of spine beams. Sling-braced trusses grace the master bedroom, furthering the fusion of traditional and contemporary aesthetics. The en-suite bathroom, an adaptation of the oak frame style, adds beauty and innovation, featuring a loft accessed by a galley-style ladder. Solutions for insulating between oak frame members while mitigating cold bridging are outlined, contributing to the extension’s successful blend of functionality and tradition.
