A seamless extension meeting past and present nestled amongst the leafy streets of O’Connor

Stepping inside the new precast concrete additions to the traditional red brick home makes for a modernised retreat that feels like a relaxed hotel lobby of a private faraway escape.

Nestled in the collected interiors of intellect and travel we find the caress of secret environments where timber louvred room dividers play with light and comfort cocooned in sustainability principles.

Based on the timeless Millennium Design, this beautiful addition uses our highly insulated precast thermal panels, slab, northern glazing, fans to achieve minimal heating and cooling and Northern entertaining areas to expand the experience of the home by integrating into alfresco living.

In the process of upgrading the new additions, we optimised the existing red brick home, improving the energy efficiency, comfort and abundant light brought into key living spaces.

House size 192m² (91m² Addition), single carport, northern pergola and south verandah.
