Northcote House by LLDS

Northcote House is a bold reimagining of a terraced house, grounded in advanced technology and sustainable design practices. By utilising computer numerically controlled (CNC) milled formwork and robotically cut blockwork, LLDS has created an eco-friendly residence on a narrow site.

Located in inner-city Melbourne, Northcote House occupies a compact plot measuring just 22 metres long and 4.6 metres wide. To address the limited garden space and support local ecology, LLDS has incorporated a green roof, which not only reduces energy consumption but also facilitates rainwater harvesting for irrigation. Below the free-form roof, the first floor features a kitchen, dining area and an entrance verandah. The wooden verandah draws inspiration from the Japanese engawa, seamlessly connecting interior and exterior spaces. On the ground floor, one can find a snug, a library, two bedrooms and antechambers that serve as utility rooms or ensuites. Three staircases promote a fluid, circular movement throughout the home. Externally, the open framework of the eastern and western facades acts as trellises for climbing plants, further integrating the house with its surroundings.

A sculptural staircase winds through the central void, creating a dramatic experience of the unique interior.

On the ground floor, the circular snug is positioned at the end of a central void, drawing natural light into the home. To the east, a minimalist bedroom boasts a concrete vaulted soffit that supports the roof above. The absence of internal doors – except in the bathrooms – also allows the client’s dog to move freely between spaces.

LLDS prioritises sustainable, environmentally friendly design throughout the residence. The home’s materials emphasise natural texture and longevity, with most elements crafted for disassembly and future alterations; only the concrete boundary wall is permanent. Reused brickwork and FSC-certified hardwood timber contribute to its eco-friendly approach. Limited concrete is cast using CNC-milled PIR insulation board, which is reused as roof insulation. To ensure structural integrity, LLDS employs a point cloud scanner to analyse data for proper bonding of hardened and fresh concrete, enabling load transfer and preventing water leakage. Additionally, many building components are locally manufactured within five kilometres of the site.

Despite its small size, Northcote House offers a variety of spatial experiences. LLDS embraces advanced manufacturing and construction techniques that align with their sustainable vision, resulting in a home that showcases the intricacies of innovative design.
