Arête Architects assemble Karaka Tower on Eastbourne hillside
Karaka Tower, designed by Arête Architects, stands as a practical resolution to a fancy steep web site in New Zealand and an open-ended consumer temporary. The house owners’ need for added house amidst a difficult terrain and an current house led to the inception of this progressive annex, offering a supplementary bed room and artwork studio. Nestled throughout the native bush of Eastbourne, Wellington, this modest 9 sqm tower exemplifies architectural ingenuity and performance.
The tower’s design centered on maximizing house with minimal footprint, achieved by stacked modular volumes. Prefabricated in a manufacturing facility, these modules have been airlifted onto a preformed platform, showcasing architectural, building, and coordination prowess. Whereas indirectly contributing to the group, the Karaka Tower units a precedent for modular building, unlocking potential throughout undeveloped websites.
Located on a closely vegetated steep hillside, the tower harmonizes with its environment whereas providing views of Te Whanganui-a-Tara. The development technique, pushed by web site entry constraints, facilitated helicopter transport in three elements, every weighing a most of 1100 kg. Materials choice prioritized environmental integration and building flexibility. The eucalypt rainscreen blends seamlessly with the panorama, requiring minimal upkeep over time.

timber framing on the inside achieves a treehouse-like really feel
To accommodate the prefabrication and on-site stacking of the constructing, a brand new waterproofing system was essential. The design included uncovered macrocarpa timber framing on the inside for a treehouse-like really feel. A inflexible air barrier and thermal polystyrene have been layered over the framing, creating an hermetic and totally thermally damaged pores and skin. To forestall direct fixing penetration from the outside to the inside, a double TPO membrane and batten system was carried out. The modules featured 300 mm membrane laps, permitting for onsite welding to make sure swift weathertightness. This detailed resolution was a collaborative effort between the design crew and Viking Roofspec, tailor-made particularly for the mission.
Effectivity was paramount all through the mission, with groundworks and constructing work continuing concurrently. The light-weight building supplies and uncovered design allow straightforward upkeep whereas minimizing environmental influence. Prefabrication in a managed manufacturing facility atmosphere maximized effectivity and minimized waste, contributing to the mission’s sustainability.
Thermal efficiency optimization and strategic detailing additional improve the constructing’s performance and longevity. The choice to airlift the tower minimized building disruption and potential environmental impacts, showcasing a considerate method to design and execution.
