Arizona-based studio Benjamin Hall Design completed an addition to a Phoenix house that hides in the landscaping to create a treehouse-like effect.

Completed in 2024, the Adkins Treehouse adds 952 square feet (88 square metres) to a 1959 ranch-style house, replacing an unpermitted addition from the 1980s, but keeping the previous footprint on the 0.3-acre lot.

Benjamin Hall Design , who recently created a concrete masonry accessory dwelling unit nearby, centred the primary suite addition on the unusual vantage point that was created by the existing trees that surrounded the site.

"The trees generated a dialogue and experience worth engaging with architecturally," studio founder Benjamin Hall told Dezeen.

He intended for the design to make people feel like they are "being immersed in the treetops while experiencing dappled light and the short but beautiful change of colours seasonally."
