Coastal blocks are why many people want to build on the Mornington Peninsula. They also ask more of a house than a suburban street does. Salt, wind, sand and planning controls all shape what you can build and how it should be detailed. Here is what to think about before you start.
Know your exposure
A home on the ocean side at Sorrento, Portsea or Rye takes very different weather from one tucked into a bayside street at Dromana or McCrae. Exposed sites face strong south-westerly winds and salt spray, which affect window ratings, roof fixing, cladding choice and the grade of every screw and bracket. Ask your builder and architect to design for the actual exposure of your site, not a generic coastal standard.
Choose materials that age well
Marine-grade stainless fixings and flashings close to the water
Cladding and decking that weather gracefully or are easy to maintain
Window and door systems rated for the wind load of the site
Details that shed water and sand rather than trap them
Spending a little more on the right materials at the start usually costs far less than replacing corroded or weathered elements a decade later.
Understand the ground
Much of the southern Peninsula sits on sandy soils and old limestone dunes, while the hinterland and parts of the bay side have reactive clay. Footings should always be designed from a proper soil test for your block. On dune sites, retaining, drainage and erosion control matter as much as the house itself.
Plan for overlays early
Many coastal blocks sit under planning controls for coastal landscape, vegetation, heritage or bushfire. These can affect the height, siting, materials and even the trees you keep. Check the overlays on your title before you finalise a design, and allow time for planning approval in your program.
Think about how the house will be used
Many coastal homes are holiday houses or homes that sit empty for weeks at a time. Low-maintenance finishes, good ventilation, secure storage for boards and bikes, and outdoor showers all make a coastal home easier to live with.
