What Baxt Ingui Architects does

Baxt Ingui Architects PC, operating as Ingui Architecture, is a privately held New York professional corporation headquartered in Brooklyn that delivers residential, institutional, and commercial architectural design services. The firm has operated for over 45 years and is self-described as an award-winning practice and a leader in design and sustainability. Its client base consists primarily of individual homeowners and families undertaking townhouse renovations, carriage house conversions, and historic district projects across Brooklyn neighborhoods including Park Slope, Boerum Hill, Cobble Hill, and Brooklyn Heights, as well as the West Village in Manhattan. Selected institutional work includes adaptive reuse conversions such as the transformation of a historic 1850s Gothic Revival church into residential units.

The firm's core technical differentiator is high-performance sustainable building design, anchored by certified Passive House expertise and what the firm describes as a repeatable template for masonry retrofits inside landmarked historic districts, first validated through a Brooklyn Heights Passive House project. Service offerings are organized across five project categories: Contemporary Townhouse, Traditional Townhouse, Apartments & Condos, Commercial & Institutional, and Suburban & Country. The practice maintains an affiliated interior design sub-brand, BIA Interiors, which collaborates on integrated residential engagements such as the Brooklyn Heights carriage house.

Revenue is generated through professional services fees on a quote-based, project-specific model. Pricing is not publicly disclosed. The go-to-market motion is direct-to-consumer client engagement, supported by an organic presence on LinkedIn, Houzz, Facebook, Instagram, and an email newsletter for top-of-funnel portfolio awareness. Marketing channels serve primarily as portfolio showcasing rather than lead generation at scale. Geographic operations are concentrated in the New York City metropolitan area, with selective extension into suburban and country residential projects. No app, API, SDK, integration, or AI/ML capabilities are disclosed in the source material.
