Coastal Architecture & Durability: Designing Resilient Homes on Complex Sites
Understanding Coastal Site Risks
Coastal properties face a range of risks, from wind-driven storms and salt spray to flooding and erosion. These factors can affect structural integrity, exterior finishes, and long-term maintenance if not addressed from the outset. buck&simple integrates architectural design, engineering, and material expertise to minimise these risks while enhancing lifestyle and aesthetic outcomes.
Key Design Strategies
Site Orientation and Layout
Positioning the home to reduce exposure to prevailing winds and salt spray, optimise natural light, and maximise views.
Design for Exposure
Planning forms, overhangs, drainage, and flood mitigation measures to minimise the impact of wind, rain, and salt air. This approach considers both immediate weathering effects and long-term climate exposure.
Durability-Focused Detailing
Selecting materials and protective coatings that resist corrosion, weathering, and marine conditions, ensuring long-term performance and low maintenance. This includes careful coordination with suppliers and installers to specify fixings, coatings, and treatments appropriate for the exposure conditions.
Material Selection & Detailing
While no single material dominates all conditions, key considerations should be investigated to achieve long-term resilience.
Roofing
Roofing must suit exposure conditions and meet applicable exposure ratings. Metal options like zinc and copper offer high performance in coastal environments. When using products such as Colorbond, it is essential that the correct grades and warranties are specified. Terracotta products resist weathering and UV exposure better than cheaper coloured concrete alternatives.
Green roofs over a superstructure require careful design to balance thermal performance, waterproofing, and landscape integration. When specified and constructed correctly, they perform exceptionally well: protecting underlying membranes from UV exposure, providing additional thermal mass, creating habitat for native flora and fauna, and reducing the urban heat island effect. In dramatic coastal environments, often environmentally sensitive and subject to scenic protection frameworks green roofs offer the dual benefits of a more recessive, landscape-integrated aesthetic while delivering measurable environmental and performance advantages. Buck&Simple carefully integrates green roofs to ensure they enhance both resilience and visual harmony with the surrounding site.
Walling
Weather protection is critical, and minimizing exposure of susceptible components reduces long-term maintenance. Timber can be a durable choice when natural resistant species such as cedar or Australian hardwoods are used. Engineered timbers, including thermally or acetyl-treated options like Abodo and Accoya, offer additional performance advantages. Protective coatings should always be specified and coordinated with suppliers and installers, with careful consideration of compatible fixings.
For longer-lasting permanence, walling can also incorporate rammed earth, concrete, ceramic, or masonry-based products. These options provide inherent durability and reduced maintenance periods, making them ideal for coastal conditions.
Glass is often a key material in dramatic coastal settings, particularly in homes designed to maximise ocean views and natural light. Modern high-performance glass offers far greater weather protection than previous generations, combining thermal efficiency, structural integrity, and resistance to wind and salt exposure. Selecting the right framing—aluminium or timber—is critical, ensuring compatibility with exposure ratings, longevity, and coastal performance. buck&simple carefully considers both the glass and its supporting systems, creating openings that capture views while maintaining resilience against the harsh coastal environment.

Risk Management & Maintenance
Effective coastal design is as much about ongoing process as it is about materials. buck&simple incorporates careful detailing, collaboration with structural engineers, and thorough site analysis to minimise future maintenance challenges. Establishing maintenance schedules and working closely with suppliers and installers ensures that the home continues to perform optimally.
