# Minimalist Net-Zero Housing Projects HK ASSOCIATES Complete the Casa Ala Blanca Project By Kalin Ned | Published 2026-08-03 | Art & Design Source: Trend Hunter, https://www.trendhunter.com/trends/casa-ala-blanca References: [archello](https://archello.com/project/casa-ala-blanca) Tucson-based architecture practice HK ASSOCIATES has designed [Casa Ala Blanca](https://www.trendhunter.com/trends/casa-culo) — a [net-zero, small-footprint residence](https://www.trendhunter.com/trends/net-zero-ready-home) in Oro Valley, Arizona, which won the 2026 Architizer A+Awards Popular Choice Award for Unbuilt Private House under 3,000 square feet. Casa Ala Blanca, which translates to 'white wing house,' reimagines [desert living](https://www.trendhunter.com/trends/desert-fairway-residence) through a single unifying architectural gesture that integrates passive environmental performance, rainwater harvesting, and everyday experience into a cohesive form. The home layers Sonoran architectural intuitions of shade protection, water collection, and indoor-outdoor entanglement, with a wing-like silhouette that creates sombrero-like shade, expanding the perceived limits of the modest 2,370-square-foot floor plan. The design is capable of capturing 3,700 square feet of rainwater surface area and providing ample opportunity for solar PV integration.
