Project - In the idyllic setting of Trancoso, southern Bahia, the SA House by 73.Onze Arquitetura stands as a masterful example of contemporary Brazilian residential architecture that respects and enhances its natural surroundings. Completed in 2023, this 1,094-square-meter residence seamlessly balances sophistication with regional sensitivity through its thoughtful composition of volumes, materials, and spatial relationships.

Led by architect Julia Regis Bittencourt, the design responds ingeniously to the site's flat topography and dense native vegetation. Rather than imposing upon the landscape, the house engages in a constant dialogue with it. The strategic organization of two perpendicular volumes preserves existing rubber and ingá trees while simultaneously framing views toward the condominium's common green space.

What distinguishes this project is its clever articulation of social and private spaces through contrasting architectural elements. The single-story bedroom wing features a flat green roof that serves both aesthetic and functional purposes, housing technical equipment while providing thermal insulation. This volume stands in deliberate contrast to the two-story main block with its more traditional pitched roof, creating a dynamic visual tension throughout the composition.

Permeability defines the spatial experience, with retractable glass panels dissolving boundaries between interior and exterior living spaces. The architecture employs a sophisticated system of wooden brises-soleil that perform multiple functions: providing privacy, controlling solar gain, and casting ever-changing patterns of light and shadow that animate the spaces throughout the day.

The interior design, also developed by Bittencourt's studio, mirrors this thoughtful approach by juxtaposing clean contemporary lines with local craftsmanship. A restrained palette of white surfaces and burnished cement flooring serves as a neutral backdrop for warm earth tones and carefully selected handcrafted pieces that root the dwelling in its cultural context.

Through its nuanced response to climate, topography and local materials, SA House achieves that elusive quality of seeming both boldly contemporary and deeply contextual – a residential sanctuary that celebrates the unique character of coastal Bahia while providing a sophisticated framework for modern living.

Design Team - 73.ONZE Arquitetura e Design is an architectural practice established between São Paulo and Trancoso, founded in 2018 by Bahian architect Julia Regis Bittencourt. With previous experience at renowned firms such as Superlimão and Paula Neder Arquitetura, the firm's architectural style combines simple elements with meticulous attention to detail.

The firm's dual-location strategy represents a conscious synthesis of seemingly opposing contexts: the restorative qualities of Trancoso's natural landscape with São Paulo's contemporary urban dynamics. This geographical duality infuses their portfolio with a unique spatial sensibility that responds to both environmental and metropolitan imperatives, resulting in increasingly sustainable built interventions.

The office was born from the fusion between Trancoso and São Paulo, combining the well-being provided by nature with the urban lifestyle, meeting contemporary demands and seeking to create increasingly sustainable buildings.

73.ONZE specializes in developing customized residential, commercial, and corporate projects, each tailored to the style and needs of each client. From conception to realization, they prioritize functionality and ethics, adapting architecture uniquely for each individual or brand.

Under Bittencourt's leadership, the studio has cultivated a distinctive architectural language characterized by volumetric clarity, material authenticity, and environmental responsiveness. Their work consistently demonstrates a commitment to crafting personalized spatial experiences that thoughtfully balance pragmatic considerations with poetic expression, establishing 73.ONZE as an emerging force in Brazil's evolving architectural landscape.
