​​​​​​​​​​​​Trinity Apartments is an L-shaped apartment building providing a mix of apartment sizes. The configuration of the building has been designed to address the two road boundaries of the site. The apartments overlook an internal west-facing landscaped courtyard and have been designed to maximise natural ventilation and lighting.

The development sits on the corner of Parnell Road and Birdwood Crescent. Birdwood Crescent is a quiet street that contains mostly older detached houses, while Parnell Road is a busy, city-fringe street with residential and commercial properties. The site is opposite the Holy Trinity Cathedral and the site marks the start of the Parnell Village retail strip.

The site slopes down from Parnell Road towards the west and neighbouring detached houses, over which there are views to the Auckland Domain and the Auckland War Memorial Museum. The 32 apartments are arranged over six floors (there are five floors visible from the street), which comprise a mix of spacious one, two and three-bedroom apartments.

The building has been considerately massed to provide a compatible scale to the street and residential neighbours. Striking vertical glass fins and recessed balconies are a feature of the building frontages. The use of stone panels at the end walls provides a sense of solidity and permanence in the urban landscape.
