Coastal design principles
Coastal design distils the sensory experience of seaside living into an interior language — salt-bleached timbers, woven textures, the shifting blue-green palette of shallow water, and an abundance of natural light. At its best it is neither nautical-themed nor literalist; instead it creates rooms that feel genuinely relaxed and connected to the natural environment outside, with materials and colours that reference the coast without reproducing it.
Prioritise natural light and window treatments that maximise it
Natural light is the defining quality of coastal interiors. Replace heavy drapes with linen sheers, remove window frames that block peripheral light, and use pale, reflective surfaces on walls and floors to carry that light deeper into the room. Light-coloured linen or cotton voile panels that move in a breeze are more faithful to the coastal aesthetic than any decorative element you could add.
Build the palette around whites, sand, and water
A coastal palette is bleached and light — white, off-white, warm sand, driftwood grey, and the blue-greens of shallow sea water. The blue-green tones should be soft and slightly desaturated; saturated navy or royal blue feels nautical rather than coastal. Use the lighter neutrals as the primary base and introduce the blue-green tones selectively through textiles, ceramics, or a single accent wall.
Choose natural, tactile materials over synthetic alternatives
Seagrass, sisal, rattan, woven cotton, weathered oak, and unglazed ceramics all carry the material sensibility of the coast. When selecting furniture and accessories, ask whether the material itself could have come from or been shaped by a coastal environment. Avoid plastic or resin equivalents of natural materials — they flatten the tactile quality that makes coastal interiors feel genuinely relaxing.
Avoid over-theming with nautical accessories
Anchor prints, ship wheels, and lighthouse ornaments signal 'beach house' rather than creating an actual coastal atmosphere. The most convincing coastal interiors rely on material quality, light, and spatial openness rather than thematic decoration. If you want a reference to the sea, a large piece of sea glass, a bowl of smooth stones, or a single botanical print of coastal flora will do more than a shelf of maritime ornaments.
Bathroom design considerations
Bathrooms present unique design constraints because every material must perform in a high-moisture, high-use environment while the room itself is usually small, fixed in its plumbing positions, and expected to look good for ten or more years without major renovation.
Waterproofing as the non-negotiable foundation
All visible finishes in a bathroom sit on top of a waterproofing system that must be correctly specified and installed before any aesthetic decisions matter. Inadequate tanking or incorrectly applied membrane systems behind tiles or cladding cause failures that are expensive and disruptive to remediate. Budget for this correctly before spending on surface finishes.
Scale of fittings relative to the room
Bathroom showrooms display products in generous open spaces that bear no resemblance to a typical bathroom's dimensions. A large freestanding bath that looks proportionate in a showroom can make a small bathroom feel unusable. Always work from accurate room dimensions and leave adequate clear space around each fitting for comfortable use.
Ventilation to prevent mould and surface degradation
Mechanical ventilation — a correctly sized extractor fan that runs during use and for a timed period afterwards — is essential in any bathroom without reliable natural ventilation. Even in bathrooms with windows, condensation accumulates faster than natural airflow removes it. Mould damage to grout, silicone, and decorative surfaces is the most common bathroom maintenance problem and is largely preventable.
