This materially rich house is designed to make the most of its sub-tropical location. Privacy is maintained from the street through layers of screening and landscape that surround the cobbled forecourt. A scalloped and curved concrete form pushes out towards the street engaging with the neighbourhood with planting spilling down the textured wall. Once visitors pass beneath the planted concrete awning, the water views reveal themselves slowly as you pass through a series of living spaces. This house plan is arranged to encourage prevailing breezes to pass through interior spaces that are rich with natural light. Screening on the first floor shifts dynamically according to required function. Upper screen folds allow views to the sky and tree canopy, while lower folds reveal garden views while maintaining privacy.

Fringe Dweller’s sculpted extension transforms an unassuming weatherboard cottage into a proud forever home. It walks multiple tightropes at once: balancing openness with privacy, strength with softness, and a rich history with our clients’ future needs. On Clifton Hill’s suburban edge, the house sits opposite the leafy Quarries Park Reserve. Our clients, Ishtar and Craig, have three children and purchased their cottage to create a long-term family home. Lying within a heritage overlay, the cottage’s traditional layout is largely preserved – only tweaked, in a wise parenting move, to form three equally sized bedrooms. The extension’s shared spaces feature rich materials, a warm palette and curved edges, creating a feeling of softness and easing transitions between zones. A staircase arcing through the living areas leads up to the lounge and main suite. Elevated above street level, these spaces can more freely relate to the park: the lounge’s attached balcony overlooks the park’s open field, while the main bedroom’s floor-to-ceiling window frames magnificent foliage. Downstairs, sliding doors connect the living areas to a semi-covered deck, while the garden beyond is embraced by a self-contained studio at the rear and high walls on either side. A brick wall interspersed with permeable screens lines the site’s public edge, balancing backyard privacy with neighbourhood connection. For passers-by, it’s a strong addition to the streetscape, granting glimpses of the lush garden within. Fringe Dweller embraces its presence on the fringe of the parklands, balancing its historical context with its future as a nurturing family home.
