Sydney House Design & Interiors is a Mosman building design and interiors studio covering feasibility, new homes, duplexes, secondary dwellings, renovations, apartments, heritage work, DA/CDC/CC documentation and interior design.
Sydney House Design & Interiors is based in Mosman and provides residential building design, planning feasibility, approval documentation and interior design services across Sydney. Its project types include single residences, duplexes, boarding houses, secondary dwellings, alterations and additions, carports, swimming pools, mid-rise apartments and heritage design. Pre-purchase feasibility can be used to understand zoning, planning constraints and possible approval pathways before a property or full design package is committed to.
The studio provides Architectural Design, Feasibility Design, Concept Design, Residential Architecture, Renovation Design, Development Application Drawings, DA Approval, Construction Documentation, Interior Architecture and 3D Rendering. Projects can begin with planning feasibility or concept feasibility, using early sketches and yield testing to establish what may be achievable before progressing into a residential design package and the relevant DA, CDC or CC documentation.
The practice works across several residential scales. Duplexes, boarding houses and apartments involve multiple dwelling relationships, while secondary dwellings and renovations require careful integration with an existing site or building. Interior design extends the architectural work into materials and FF&E schedules, allowing internal spaces and building design to develop together.
