Can you imagine fitting a jamming area for him and a dressing room for her in a 579 sq ft apartment? Add to that space to hang two bicycles and ample room to play darts.Heiman Chan, founder of Deco Farmer Studio, can – and did – for his client, Geoffrey Wong, a first-time homebuyer who aspired to create “a happy home” in the Tsuen Wan neighbourhood where he’d rented for several years. The fitness enthusiast enjoys the area’s cycling paths and sports amenities, and he finds the sea views calming.To achieve the happy vibe, Chan infused the home with a rainbow of colour. Doors in sunny yellow, sky blue or fire-engine red are set against a base palette of contemporary black and white in a joy-filled space where even the air conditioner is candy-coloured.The vestibule.

Chan’s solution was to create a vestibule beside the entrance, where two bikes hang on walls lined with multicoloured, vintage-inspired tiles.Below them, banks of cupboards reach wainscot height, storing a range of sporting kit, while a clear-glass panel maintains a visual connection to the living area.
