Renton Hall House Extension by WT Architecture

Renton Hall House Extension, designed by WT Architecture, is a sensitive residential intervention that revitalizes a 200-year-old country manor in the United Kingdom, carefully balancing architectural restraint with contemporary living. Left vacant and neglected for over a decade, the historic manor, and its expansive walled garden untended for nearly a century, presented both a challenge and an opportunity: to reimagine domestic life while honoring the site’s deep architectural and landscape heritage.

The new extension is positioned to the east of the original house, deliberately drawing living spaces outward into the garden landscape. By orienting the addition toward sunlight, long views, and the historic walled garden, the project establishes a visual and spatial dialogue between old and new. This extension does not compete with the manor; instead, it creates a conversational relationship, acting as a quiet architectural backdrop that supports the gradual restoration of the extensive gardens.

Architecturally, the extension takes cues from vernacular typologies commonly found on historic estates, such as ancillary stables and garden outbuildings. Its form and character remain deferential to the grandeur of the main house, ensuring the historic hierarchy is preserved. The new volumes appear grounded in the landscape, with generous living spaces that feel as though they are borrowed directly from the garden itself.

Materiality plays a central role in achieving this balance. A composition of robust, lime-rendered masonry walls anchors the extension within the site, referencing traditional construction while providing a sense of permanence. In contrast, the primary structural framework is crafted from sustainably sourced British Douglas fir, lending warmth and tactility to the interiors. This timber language continues through doors and opening windows, while external larch cladding and screening further reinforce the building’s relationship with its natural surroundings.

Carefully detailed frameless glazing introduces lightness and transparency, creating a deliberate contrast to the mass and solidity of the masonry walls. These glazed openings blur the boundary between interior and exterior, strengthening the connection to the gardens and allowing seasonal changes to shape the experience of the home. Overhead, a roof of hand-pressed zinc gently sails across the extension, adding a refined contemporary layer while maintaining a subdued profile.
