The replacement extension distinguishes itself from the main house in terms of materials and appearance, while still harmonising with the existing architecture. Weathered brick walls matching the existing masonry are proposed, with large openings and painted metal-framed glazing to maximise natural light. The design maintains a connection to the garden and features a chimney element that complements the existing roofline. The new structure offers enhanced functionality and insulation, incorporating underfloor heating, new windows, and a wood-burning stove. Overall, the design ensures a seamless integration of the orangery replacement while improving its thermal performance and aesthetic appeal.
