A 4,700-square-foot bungalow in Selangor by ID Candy applies a four seasons interior design concept to organise its interiors around natural materials, passive ventilation and biophilic principles
House 37 does not announce itself quietly. The entrance, a combination of stone cladding and a wooden front door set within clean horizontal lines, establishes the material vocabulary that will repeat throughout the home. Inside, the entryway’s stone wall, lit from above, signals that this is a house interested in something beyond surface finish.
The project is a 4,700-square-foot bungalow in Setia Eco Park, Selangor, designed by Kuala Lumpur-based interior design practice IDCandy. It is organised around a four seasons interior design framework in which each floor corresponds to a different time of year, and the transitions between them are given architectural weight.

“The idea of ‘Interwoven Oasis’ is inspired by the need to reconnect back to nature in our own safe space,” says Reina Lu, founder and principal designer of ID Candy. “It essentially goes back to the Sustainable Development Goals. My design’s main concepts play with themes of seasons distinguished in the two-storey house.”

Visitors enter on the first floor and descend via a panoramic elevator to the lower ground floor, where the four seasons interior design concept takes its most literal form. The design here draws on raw concrete, stone and metal. The aesthetic is industrial, but the intention is thermal: in a tropical climate, the lower floor’s enclosed, cave-like character is meant to evoke coolness and containment.

The dining area anchors this level, arranged around a long industrial-inspired table suited to large gatherings. Adjacent to it, a dry kitchen features a dark island that doubles as a breakfast bar, with ovens and a wine fridge concealed behind flat-front cabinetry. A bedroom at this level continues the dark material palette, with concrete walls and a bathroom fitted with dual sinks set in blue glass basins and a freestanding bathtub in the same tone.

The autumn zone sits between the two primary floors and is expressed as an open-air well at the centre of the plan. A lava stone wall, sourced from Bali, runs vertically through the space and gives onto a planted interior garden at its base. The air well functions as a ventilation shaft, drawing air through the home while also providing a visual and spatial buffer between the winter and summer floors. “The open airwell is a central, vertical space designed to connect multiple levels,” Lu explains. “It serves as a natural ventilation and filtration conduit that allows fresh outdoor air to enter the building while also facilitating heat recovery.”
Large glass walls opposite the air well open onto an exterior spring garden, where planted pathways and a water feature are designed for biophilic engagement. Open stairs cross over an indoor pond, offering an alternative route to the upper level.

The upper floor is where the four seasons interior design logic feels most resolved. Herringbone timber flooring and tall windows fill the master bedroom with daylight. A home office at this level features a custom-made timber desk with an irregular profile and curved corner cabinetry. The master bathroom is fitted with wavy reflective tiles at the vanity and a freestanding bathtub positioned on a bed of decorative stones. Motorised blinds allow occupants to adjust light levels. A walk-in wardrobe runs the length of an adjacent room, with full-height timber cabinetry on both sides, some of which is fronted in glass.

Lu built the sustainability requirements into the four seasons interior design brief from the outset. The house runs on solar panels and collects rainwater, while materials were sourced with environmental impact in mind — among them the lava stone wall from Bali. The practice framed these decisions around the United Nations’ 2030 Sustainable Development Goals, with a focus on climate action and responsible material consumption.

“The whole concept of the house ties back to the idea of sustainability and comfort, and bringing back nature into the home,” Lu says. “Which is why I integrated many greens throughout each space.” The result is a four seasons interior design approach that treats the home not as a static object but as a system responsive to its occupants and its environment.
