At BSB Design, the mission is clear: everyone deserves a home designed by an architect. Founded in 1966, the firm has continually evolved its approach to residential design—from single-family homes to large-scale multi-family developments.
Now, BSB Design is leading the way in how architects approach site planning by integrating AI tools in their design process like TestFit—dramatically reducing feasibility study timelines, improving client engagements, and unlocking new efficiencies.

Reaching the “Does It Pencil?” Moment in 1 Day
The first question in any real estate feasibility study is: “Does it pencil?”—that is, whether it meets the financial and spatial feasibility for development. BSB Designs helps its developer clients confidently answer this question by utilizing TestFit for real-time insights into design, cost, and constructability.

Before adopting TestFit, BSB Design’s site studies took up to 2 weeks—with each land plan alone requiring 4 working days in CAD. Relying on manual CAD work, the team was facing challenges such as:
- Handoff inefficiencies: Multiple handoffs between land planners, designers, and production teams increased the risk of miscommunication and errors.
- Long turnaround times: A typical site study could take days, delaying key decisions on whether a site “pencils.”
With TestFit, BSB Design has now cut its feasibility study process to just 1 days. This 75% reduction in cycle time gives developers fast, data-driven answers—ensuring that only viable projects move forward.

Generating 8-10 Design Schemes in Real Time
A key innovation in BSB Design’s new workflow is the use of TestFit during client meetings. Instead of relying on lengthy emails back and forth, the team presents up to 8–10 design options live on screen, enabling immediate discussion and adjustment.

This real-time approach allows clients to explore different scenarios—from unit mix options to parking configurations—and instantly understand the financial implications of proposed changes.
For BSB Design, the on-the-spot engagement not only speeds up decision-making but also slashes the revision cycle—ensuring that client feedback is instantly integrated into the design process. And the best part? The faster the client can make decisions, the faster a feasibility study turns into a real project for BSB Design.

Reinvesting Saved Hours into Staff Development
Efficiency isn’t just about speed—it’s about smart reinvestment of time. BSB Design’s integration of TestFit has freed up valuable hours that can be redirected into staff development, AI innovation, and cross-training.

For instance, by automating the boring tasks with generative design and streamlining communications with TestFit’s deal viewer, the firm estimates that they’re saving 3 days per land plan.
What can one do with 3 extra days? BSB Design is using this additional time to train its team in AI innovation, ensuring every architect and designer is equipped with future-ready skills.

Scaling the Practice with Unit Library
One of these innovations is BSB Design’s integration of its unit library into TestFit, allowing the firm to customize site solutions for diverse local markets while meeting their clients’ standards.

By importing their unit types into TestFit, the team can quickly adapt designs based on changing market needs—whether that means modifying unit mixes, tweaking parking ratios, or adapting elevations to match regional aesthetics.
In one notable case, BSB Design was able to produce a complete permit set in just 30 days for a multi-family project by rapidly iterating design options with different unit mixes that met both developer and municipal requirements.
This scalable approach not only enhances design precision but also ensures that BSB Design stays future-proof in its offerings—blending traditional craftsmanship with modern technology.

A Future-Ready Workflow
By integrating TestFit and AI into every phase of its design process, BSB Design has redefined what’s possible in residential architecture. Faster site studies, real-time client collaboration, significant cost savings, and scalable innovation are not just buzzwords—they’re measurable ROI driving the firm’s success.
As BSB Design continues to invest in its people and processes, it remains committed to delivering homes that are both financially viable and architecturally exceptional.
