Modern residential design by Agruppo featuring the Groveland House in Dallas, Texas. A two-story home on a narrow urban lot with open living spaces, clerestory windows, and deep overhangs that blend indoor and outdoor environments.
Architecture Firm Dallas TX
A.GRUPPO Architects LLC is a Dallas-based architecture firm founded by Andrew Nance AIA and Thad Reeves AIA — two licensed principals with more than 30 years of combined experience designing modern and contemporary residences across Dallas, the DFW metro, and North Texas. Founded in 2005, the firm has built a reputation for thoughtful site-responsive design, rigorous detailing, and a client-centered process that carries each project from initial concept through construction administration.
A.GRUPPO operates from its Dallas studio at 3800 Main St E, Dallas, TX 75226, with a branch office in San Marcos, TX. The firm serves homeowners, developers, and design-forward clients who are building, transforming, or expanding a home and want an architect — not a builder — leading the process.
Design-Build Architect Dallas
A.GRUPPO approaches every project through a design-build lens — meaning architecture and construction coordination are integrated from day one rather than handed off. This model gives clients a single point of accountability, tighter budget alignment, and design decisions that are informed by real buildability from the start.
For Dallas homeowners, this means fewer surprises during construction, less scope creep, and a finished home that reflects the original design intent rather than a value-engineered version of it. Andrew Nance AIA and Thad Reeves AIA have used this integrated approach on named projects throughout Dallas and the DFW metro, including multiple AIA Dallas Tour of Homes selections.
Custom Home Design in Dallas TX
A.GRUPPO designs custom homes from the ground up — each one developed around the client's site, program, and way of living. The firm does not work from stock plans. Every project begins with an architectural analysis of the lot, the neighborhood context, and the client's spatial priorities before a single line is drawn.
Projects have been completed in Little Forest Hills, Urban Reserve, Greenway Parks, Southlake, Highland Park, University Park, and across the broader DFW metro. Named works include the Groveland House, 16 Vanguard, 17 Vanguard, Carroll Residence, and Southlake Residence — each selected for publication or recognition within the Texas architecture community.
Home Renovations and Additions in Dallas
Not every A.GRUPPO project starts with an empty lot. The firm has extensive experience transforming existing Dallas homes — expanding square footage, reconfiguring floor plans, updating envelope performance, and bringing architectural coherence to homes that have been added to or modified over time.
The Emerson Residence renovation in Greenway Parks is one example of the firm's approach: a sensitive, site-aware addition that extended the home's living area while preserving its relationship to a mature landscape.
Dallas Architecture Firm Serving DFW Metro
A.GRUPPO serves clients throughout Dallas and the DFW metro, including Dallas, Fort Worth, Plano, Frisco, McKinney, Arlington, Southlake, and University Park. The firm has completed named projects in several of these communities and maintains active relationships with contractors, consultants, and municipal planning departments across the region.
Clients outside the immediate Dallas area are welcome — the firm's integrated project management process is designed to work effectively across the metro.
A.GRUPPO has been selected for the AIA Dallas Tour of Homes multiple times, including 16 Vanguard (2016), 17 Vanguard (2018), Trammel Residence (2018), and Carroll Residence (2022). The firm received the AIA Dallas Contractor Award in 2021 and has been featured in Texas Architect, D Magazine, and national architecture publications.
