A Structural Engineer’s Perspective
Residential Design, Drafting & Approval Expertise
___________
From acreage residences to contemporary family homes, our custom homes are designed around your site, lifestyle, budget and approval pathway. We consider orientation, natural light, ventilation, privacy, bushfire risk, BASIX requirements and buildability from the outset. From concept design through DA, CDC and Construction Certificate documentation, we prepare and coordinate the drawings needed to move your project towards construction.
Whether you are expanding your living space, capturing views or modernising an existing home, we design extensions that improve functionality, natural light and everyday living. Projects range from rear and ground-floor additions to substantial first-floor extensions and outdoor entertaining areas across Sydney. We assess structure, access, setbacks, overshadowing, privacy and approval requirements early, so the new work integrates naturally with the existing home and is practical to approve and build.
Heritage projects require a clear understanding of conservation controls, heritage overlays, Local Environmental Plans and Development Control Plans. We design extensions and renovations that support contemporary living while respecting the original home’s form, rooflines, proportions, materials and streetscape character. For every heritage project, we engage and coordinate a qualified heritage consultant to provide specialist advice and prepare the Heritage Impact Statement. We also manage council liaison through the DA process, helping ensure the new work is carefully considered in relation to the existing home and its heritage significance.
A knockdown rebuild lets you create a home tailored to your site, lifestyle and future needs while remaining in the location you already know. We design for sloping blocks, narrow frontages, acreage properties and complex planning controls. Site levels, access, orientation, setbacks, drainage, bushfire risk and approval requirements are assessed early, so the new home responds naturally to the block. We prepare clear DA, CDC and Construction Certificate documentation to support the project through approval and towards construction.
Designing on bushfire-prone land requires a clear understanding of BAL ratings, Flame Zone requirements, planning controls and construction standards. We integrate bushfire-responsive design with site planning, orientation and passive solar principles to support safety, comfort and long-term performance. Our portfolio includes homes designed for BAL-29, BAL-40 and BAL-FZ sites, showing that strong architectural outcomes can be achieved while addressing demanding bushfire requirements.
Dual occupancy, duplex and townhouse projects require careful consideration of zoning, lot size, frontage, parking, private open space, waste access, overshadowing and neighbourhood character. We develop efficient layouts and practical planning strategies that respond to the site while supporting market appeal and development potential. From initial feasibility through DA or CDC documentation and council lodgement, we coordinate the drawings and technical requirements needed to progress the project towards approval and construction.
Sustainable design principles are integrated into every project, with careful attention to orientation, passive solar design, natural ventilation, thermal mass, glazing and material selection. These decisions are considered early to improve comfort, energy efficiency and year-round liveability while supporting BASIX and NatHERS requirements. Luke’s Master’s Degree in Sustainable Design brings specialist knowledge to the design process, balancing environmental performance with practical residential design.
Navigating DA, CDC and NSW Planning Portal requirements can be one of the most complex parts of a residential project. We review the site and planning controls, identify the likely approval pathway, prepare architectural drawings and coordinate consultant information for council or private certifier lodgement.
By addressing planning risks and documentation gaps early, we help reduce avoidable redesign and provide builders, consultants and homeowners with a clearer, coordinated set of documents before construction begins.
Every project begins with a design consultation and review of your site, brief, budget and planning controls. We identify site constraints, the likely approval pathway and required consultant inputs early, then develop the design and documentation through clear, coordinated stages.
This process supports accurate drawings for DA, CDC or Construction Certificate applications and helps reduce avoidable surprises as the project moves towards construction.
