The development at Princess Street, Rose Bay comprises three multi-level luxury townhouses, expertly built by Trescon and designed by ROOZ Studio. Set within one of Sydney’s most sought-after harbourside suburbs, the project blends architectural ambition with structural precision to deliver a boutique residential experience defined by quality, efficiency, and craftsmanship.
Each townhouse offers a vertical layout serviced by private lifts from a shared basement level, delivering the convenience of apartment living with the privacy and spaciousness of a standalone home. This format was a strategic response to the site's tight footprint and sloping terrain, allowing for maximum liveability within a compact urban lot.
Construction began with the demolition of an existing dwelling and extensive excavation works. A contiguous piled wall system, supported by capping beams and shotcrete, was used to retain the site perimeter during basement excavation, a critical engineering move given the tight access and urban constraints.
The building’s structure consists of reinforced concrete slabs, masonry, and steel framing. Modern wall systems including Dincel and AFS were used for speed, consistency, and precision, particularly in the lift shafts and selected structural walls. The party walls between each residence were constructed using cavity brick masonry with insulation, providing excellent acoustic and fire separation.
Externally, the townhouses feature rendered masonry finished to resemble off-form concrete, paired with standing seam Colorbond cladding on the upper levels. Large sliding and bi-fold aluminium doors, skylights, and floor-to-ceiling windows maximise natural light and reinforce the indoor-outdoor lifestyle of each home.
A signature element of the design is the grand pivot entry door on each residence, finished in a rich timber veneer, setting a tone of craftsmanship from the outset. Internally, the homes are fitted with engineered timber flooring in living zones, plush carpeting in bedrooms, and full-height porcelain tiles in wet areas. Feature walls in the bathrooms, including Carrara-look tiles and micro-cement accents, provide textural contrast and visual depth.
The construction program, completed over approximately 68 weeks, was tightly managed with a full-time site team overseeing structural works, services coordination, and internal finishes. Despite the narrow street frontage and zero-lot boundaries, the team delivered a seamless build, including the integration of smart building technologies, underfloor heating, pre-wired security systems, and ducted air conditioning.
Innovative site solutions included the installation of two car turntables in the basement, allowing vehicle access and egress without the need for conventional drive aisles, a critical space-saving measure on a constrained site. Mechanical ventilation in the basement is automated via CO sensors, enhancing both safety and energy efficiency.
Sustainability measures were embedded through smart design and compliance with Section J requirements. Insulation was applied throughout the walls, roof, and basement soffit, while passive design elements such as double glazing, thermal mass, and external shading help to naturally moderate indoor temperatures. Rainwater harvesting and an on-site detention system contribute to water management and landscape irrigation.
Princess Street is a strong example of Trescon’s ability to deliver architecturally complex builds in tight, high-value residential contexts. The end result is a collection of homes that are as functionally robust as they are visually refined, built to the highest standards of quality, durability, and contemporary living.
