If you have a north-facing courtyard that receives limited direct sunlight and tends to stay damp, choosing the right furniture material is crucial to prevent mold and mildew. The constant moisture and shade create an ideal environment for fungal growth, which can ruin many common outdoor materials. To combat this, focus on non-porous, quick-drying, and inherently rot-resistant options.
Your best choices are aluminum, synthetic resin (like polypropylene or HDPE), and properly treated teak. Aluminum is a top contender because it is completely non-porous, rust-proof, and dries almost instantly after rain. Powder-coated aluminum adds an extra layer of protection and comes in many styles. Synthetic resin wicker or all-weather furniture is another excellent option. High-quality resin is designed to withstand moisture without absorbing water, making it highly resistant to mold and easy to clean.
For a natural wood look, teak is a premium choice due to its high natural oil content, which repels water and resists decay. However, ensure it is genuine, grade-A teak. Avoid absorbent materials like untreated wood, fabric cushions that aren't specifically outdoor-rated and quick-dry, and low-quality metals that may rust.
Regardless of material, ensure good airflow by not pushing furniture directly against walls and consider lightweight pieces you can occasionally move. With the right material selection, you can create a stylish, durable outdoor space that withstands the challenges of a shaded, damp urban courtyard.
