You might not realise it but coastal plots don’t follow the same rules as inland builds when it comes to material selection. What looks like a simple white box is actually a heavily engineered response to wind, salt, and shifting ground. Sea air accelerates corrosion, timber degrades faster, and standard material choices start to fail far sooner than expected. In this case, durability drove every decision, from dense blockwork to reinforced concrete and protective coatings. It’s a clear reminder that on exposed sites, material selection needs to be a strong consideration.

Budget For Unexpected Costs

Always prepare for potential budget overruns. A 10% contingency is a good start, but consider allowing for 20% based on your project’s complexity and personal choices that may arise during the build.
