394 Alexandra Road is believed to be a family home for a high-ranking official, possibly the railway superintendent, of the former Malayan Railway.

Designed in the Arts & Crafts style, the building features a steeply-pitched tile roof and gable wall arranged asymmetrically. According to the Urban Redevelopment Authority, the band of brick skirting around the base of the building and its chimney gives an overall impression of the 1930s country cottage. A protruding central bay, balcony and slender concrete ledges could be found at the front façade of the building, where a low flight of steps bring the main entrance out to the building.

Within the building, the windows are timber framed with small panel glass and the mixture of high- and low-level slotted concrete vents facilitate air movement through the internal spaces.
