Stackbrae is an entire street of good-quality, architect-designed homes that are orientated to the sun and the views of the mountainous landscape around Wanaka. This award-winning development of 31 homes offers an alternative model for suburban housing.
Group-home design and build companies currently dominate the housing development market, with architects and architectural designers rarely influencing this slice of the pie. However, at Stackbrae, Arrowtown-based studio Assembly Architects and Wanaka-based developer Satomi Holdings did things a bit differently. They created a model that would create a more cohesive development, which halves the design and consenting time, as well as reducing the associated cost for the purchasers – ensuring that homes could be built without delay after settlement.
“We adopted a different product/model than other housing developments in Wanaka, with the aim of improving and speeding up the process,” explains architect Justin Wright. “It was a good time in the market to do this,” says Justin. “In the past decade or so, a lot of new suburbs have arisen in the Wanaka area with no or little design controls, with some average design outcomes. Developments with design controls generally improve the design outcomes, but these create an expensive and slow process for buyers. Many people have been dissatisfied and our developer didn’t want that result – we wanted to raise the design standard and add some flexibility into the process.”
“At Stackbrae, we halved the time to get on site, compared with similar developments, which typically takes around six months to get through the initial process. This meant that buyers of homes at Stackbrae were able to purchase the land and start building on site within 16 weeks of signing up,” says Justin.
Long before the Stackbrae project began, Satomi Holiding’s Stuart Pinfold had commissioned Assembly Architects to design for him a rammed-earth house across the road from the site, where he realised that he wanted to create a more ‘design-influenced’ suburb nearby. Firstly, he gained resource consent to create the laneways on the land and, then, sought architects who would create a strong design outcome that would maximise sun, privacy, views and quality outdoor space.
The resulting 31 homes shares a consistent design language but each one varies little bit to create variety. House sizes and shapes differ, as does the orientation and material palette. Claddings come in timber, brick or masonry, or combinations of those. “They share similar elements but every house is unique to start with,” explains Justin. “Each is a little bit different than the others and these variations are also a good talking point within the Stackbrae community.”
The developer didn’t want to construct the actual buildings, so the land packages were sold with consented plans and a covenant to build. “Half the houses were purchased by the residents and one of the builders liked it so much, he bought a land package and moved in,” remarks Justin. “The real estate agents were resistant to the model at first but, because the houses are efficient to build and consent process was smooth, and they were up and running quickly, they soon came around.”
The 2.5ha site has a low slope to the north, with great views to the east and west. The house designs are either stand-alone or duplex arrangements and are configured much like courtyard houses – with L-shaped plans and massing on the lot edges to draw sun into the middle of the sites – directly challenging the district plan setback rules. The walls on the boundary have no windows and are rendered in durable materials to avoid fencing.
With efficiency in mind, Assembly has designed the houses with good thermal envelopes to reduce energy bills and to ensure comfort, and they utilise economical construction methods to keep the costs down. Whilst Stackbrae isn’t intended to be ‘affordable housing’ as such, this model places architect-designed homes at a more accessible price point than is typical.
The development comes complete with a landscaping guide with three different types of planting laid out in the plans. The landscaping is currently being completed but, unlike other developments, there are no empty lots left on the site. “The Stackbrae community is already up and running and is more established than some subdivisions that were started 10 years ago,” suggests Justin. “The residents have found that the quality of the houses is so much higher than what was expected and they are some of the happiest clients we’ve ever had.”

Assembly is an Arrowtown based architecture practice delivering exceptional architecture with personality, connection to landscape and considered construction.
We design homes and special projects in the Queenstown Lakes district, Wanaka and Central Otago. Current projects include heritage sensitive homes in Arrowtown, a rammed earth home in Wanaka, and distinctive new homes at Mount Cardrona Station, the Crown Terrace, Ben Lomond and Lowburn Mt Pisa.
Our homes are decidedly personal and individual, strongly connected to landscape, and expressed with detailed materiality. Design communication is huge to us. We utilise design tools that visually communicate the design in an engaging, interactive and visually realistic method.
Registered Architects Louise Wright and Justin Wright established Assembly in Wellington in 2005, and moved to Arrowtown in 2012. Our Arrowtown studio is situated on Arrow Lane in the heart of Arrowtown’s historic town centre.
The studio comprises a tight knit and talented team – Emma Schmitz, Marcus Kirk, Simon Khouri, Catarina Peeters and Matt Connolly, who together with Justin and Louise work in small teams to bring your design to life
In 2019 Assembly was a founding signatory to the NZ Architect’s Declare Climate & Biodiversity Emergency.
Assembly is a New Zealand Institute of Architects practice.
