OVERVIEWSplit House is a residential retrofit of an existing townhome in Houston, TX, first designed by Arquitectonica, an Architecture firm based in Miami, Florida. The townhome was constructed in 1984 during the housing boom in Houston, Texas, and is one of six that make up the overall structure.
The retrofit was a three-year process that aimed to bring the spatially amazing but poorly constructed house up to contemporary detailing and to resolve and remediate the water-damaged structure and envelope. A combination of a third-floor patio positioned over a conditioned space aggressively leaking and a full-width skylight failing necessitated a deep retrofit. The scale of the damage required the replacement of a large portion of the structure—the construction techniques and detailing exacerbated the extent of the damage. The primary cladding was a directly applied stucco without accounting for a drainage plain or weep screed. The stucco, sheathing, and envelope control layers were rebuilt as part of the retrofit. Alongside the remediation, the retrofit aimed to enhance the previously compartmentalized floor plans.
