The Heights historic neighborhood, situated simply north of downtown Tulsa, Okla., has loved a revival over the previous few many years. Previously generally known as Brady Heights, the neighborhood had been named for W. Tate Brady, a founding father of Tulsa in 1898 and a profitable businessman and politician. Many residents believed, nonetheless, that his membership in each the neo-Accomplice group Sons of the Confederacy and the white supremacist group Ku Klux Klan outweighed his industrious legacy, and the neighborhood affiliation voted to vary its group’s title in 2021.
Listed on the Nationwide Register of Historic Locations since 1980, The Heights and plenty of of its homes mirror the numerous tastes of unique house owners, setting an architectural customary for middle- and upper-class developments. Through the years, the group has grow to be close-knit by renovations of its eclectic residences, encompassing architectural kinds corresponding to Queen Anne, Victorian, Georgian Revival, and Craftsman. One new addition, a 3,550-square-foot, rammed-earth home by the native agency 1Architecture, continues the group’s eclectic custom, including Prairie Faculty influences into the combination and furthering the dialog surrounding sustainable residential development.
Nick Denison, Assoc. AIA, a 1Architecture principal, was approached by a pal in 2017 to design a residence in The Heights. As a delegated historic neighborhood, The Heights has quite a lot of restrictions and insurance policies for newly constructed properties, together with architectural kinds. Inspired by the location’s sloped profile, 1Architecture urged a Prairie Faculty–type undertaking, emphasizing the horizontal reasonably than the vertical by bands of home windows, striated exterior partitions, and “low-slope hip roofs that assist showcase the [exterior walls],” Denison says.
However the undertaking, finally dubbed Terra Heights, has one other defining characteristic: The home is constructed of rammed earth, a fabric that the Terra Heights purchasers because of its low embodied power and sturdiness. In the end, over 90% of the undertaking’s mass was sourced from inside 100 miles of the development web site; the residence additionally options environment friendly operational programs and, at the side of its supplies, is designed to final a number of generations.
The undertaking, accomplished in 2019, greets guests with a sweeping cantilevered roof, spanning a depth of 13 toes. Whereas the extension initially known as for a metal body, the design was simplified to wooden development. The inside encompasses a split-level principal ground and a partial second story. The kitchen and eating areas, situated towards the again of the home, are raised to accommodate the slope of the location. Impartial, earthy tones of white finishes, wooden accents, and concrete flooring intensify the development. Denison selected this palette as “every part works in tandem with the feel and coloration” of the rammed earth partitions.
Terra Heights is one in every of 4 constructions designed to accommodate a multigenerational household. Adjoining to the location is a Craftsman residence for the proprietor’s dad and mom, with every property containing an on-suite hooked up to a storage. The 2 properties are linked by adjoining courtyards, offering a possibility for public interactions among the many households; nonetheless, every residence accommodates personal areas for intimate moments. The gathering area encompasses a rammed earth hearth and open rustic metal pergola, extending the inside earthy tones into the outside. Board kind concrete partitions help within the division of the areas in addition to additional emphasize the horizontality of the general design. The partitions of the courtyards additionally help in safety from sizzling summers and excessive winds.
Although 1Architecture doesn’t sometimes design residential properties, Denison loved engaged on a undertaking that was “extra kind becoming for human dimension.” The size, aesthetic, and design of Terra Heights features as an admirable modern residence in The Heights historic neighborhood.
