Z Group Featured by D5 Render: Where Architectural Vision Meets Visualization Technology
Updated: 1 day ago
Exploring the intersection of design, innovation, and architectural storytelling
Great architecture and interior design begin long before construction. It takes shape through conversation, exploration, and the ability to envision how a space will look, feel, and connect with the people who experience it.
At Z Group Architecture & Interior Design, a practice rooted in Aspen, Colorado, since 1952, the design process brings together decades of architectural expertise, a deep understanding of place, and an evolving approach to technology. From custom mountain residences to commercial and community-focused environments, the firm's work is guided by a belief that meaningful design should reflect its surroundings, respond to its purpose, and tell a story unique to each client.
Architectural visualization plays an important role in that process. By translating design concepts into compelling visual experiences, the team can explore materials, natural light, spatial relationships, and the connection between architecture and landscape—helping clients better understand a design as it develops.
Z Group was recently featured in a case study by D5 Render, highlighting the relationship between architectural design and visualization technology. The feature offers a behind-the-scenes look at how digital tools support the firm's creative workflow and commitment to thoughtful, collaborative design.

Beyond Rendering: Architectural Visualization as a Design Tool
"Visualization has become part of how we design. It lets us look at architecture, interiors, materials, light and landscape together, when there’s still an opportunity to ask questions and make it better." —Scott McHale, Z Group Principal and Director of Design
Key Takeaways
Visualization moves upstream: D5 evolved from final rendering into a tool used from early concepts through design development, construction, and client communication.
Faster visualization creates room to explore: Quicker turnaround lets the team test more options and brings visualization into everyday design decisions.
One visual language connects people, design, and place: Visualization helps designers, collaborators, and clients understand architecture, interiors, and site conditions together.
Technology supports design judgment—it doesn’t replace it: D5 and AI tools support exploration and communication while keeping architectural intent and human judgment at the center.

For Z Group Architecture & Interior Design, there is rarely a moment when a project is simply “finished” and ready to be visualized. The practice approaches architecture and interiors as one connected experience, from how a building sits on the land to how its spaces, materials, and light feel inside.
Its highly custom projects continue to evolve as the team responds to the client, site, interiors, landscape, and decisions that emerge along the way. “We’re designing from start to finish, and even through construction,” explains Seth Hmielowski, Z Group Principal.
That makes architectural visualization useful well before the final image. D5 initially entered the practice for photorealistic marketing imagery, but as visualization became faster and more accessible, it moved earlier into the workflow. Today, it supports everything from concept studies and design decisions to client conversations, public presentations, and sales imagery.
The shift is subtle but important: visualization no longer only follows design. Increasingly, it accompanies design as it develops.
Designing From the Inside Out
Based in Colorado’s Roaring Fork Valley, Z Group works across residential, hospitality, commercial, and multiuse/multi-family projects, as well as master planning. Its Mountain West setting means every site brings a different set of conditions. A house might sit along a river, within downtown Aspen, beside a ski resort, or against dramatic mountain terrain.
But the firm’s process doesn’t begin with the view.
It begins with the client.
Z Group describes its approach as designing “inside out.” Before deciding what a house should look like, the team tries to understand how someone will actually live there.
Do they spend mornings drinking coffee while watching the sunrise? Do they entertain frequently? Are they there year-round, only in winter, or primarily in summer? Do they need space for skis, mountain bikes, fly-fishing equipment, or ATVs?
Those conversations begin to shape the plan. From there, the design expands outward, responding to topography, landscape, views, sunlight, vegetation, weather, access, and context. Rather than imposing a predetermined design language, the goal is for each project to feel specific to its setting, purpose, and people.
“Every project is so unique in the mountains,” Evan Weller, Z Group Architectural Designer says.
That combination of personal and physical context creates a challenge: many of the qualities that matter most to a project are difficult to communicate through plans and sections alone.
A drawing can show the dimensions of a room. It is harder to communicate what standing inside that room will feel like—or exactly what someone will see through its windows.
This is where visualization starts becoming useful.
From Final Imagery to an Everyday Tool
Visualization has long been part of Z Group’s toolbox. The studio avoids prescribing one rigid process, moving between hand sketching, Revit, SketchUp, Rhino, D5, Photoshop, Lightroom, and increasingly AI depending on the project.
What has changed is how practical visualization has become.
Before D5, producing imagery with the realism clients expected could require significantly more work. Today, the team might produce “10 images in an hour,” whereas five or six years ago the same number could have taken multiple days.
At first, D5 played a traditional role: creating clean, photorealistic marketing imagery. But as the team became familiar with it, its role began moving upstream.
“I think now that we’ve onboarded D5 into the firm and into our workflow, it does come in quite a bit earlier,” Evan says.
Today, there is no prescribed point when D5 enters a project. Depending on the need, it can support early concepts, design development, construction documentation and administration, public presentations, or final sales imagery.
Instead of a linear process:
Design → Model → Render → Present
Visualization becomes part of a more continuous loop:
Design → Visualize → Discuss → Refine → Visualize again → Decide → Continue designing
Seeing More Means Exploring More
Faster visualization matters because it changes how often the team can use it.
Z Group’s designers work with plans, sections, and 3D models every day. Their clients don’t necessarily share the same spatial vocabulary. Visualization creates a common language, shifting conversations from interpreting drawings to understanding experience: How will this space feel? What will I see? How do these elements work together?
On one project, a prominent stair became a major design question. The team had a preferred direction, but drawings alone weren’t enough to communicate why it worked.
They visualized the options.
Once the client saw each proposal in context, they agreed with the team’s preferred direction.
Later, the team used D5 to explore roughly 25 possibilities for a fire pit—not as an isolated object, but in relation to the surrounding space and how someone would experience it.

That speed also creates room for experimentation. “Being able to do it more quickly,” Architectural Designer Max Hemmy says, has introduced “a certain level of creativity of exploring more options,” particularly around materials.
This is where rendering speed becomes more than a productivity claim: When visualization becomes easier to produce, it can move beyond major milestones and become part of everyday decision-making.
A Shared View of the Project
That same visual clarity also matters inside the studio.
Z Group doesn’t operate with a separate visualization department. Designers creating renderings are often the same people developing drawings, attending client meetings, and coordinating consultants. The team estimates that around eight people are reasonably proficient in D5.
That makes visualization part of the broader project conversation.
Several people might gather around a screen, move through viewpoints, adjust something, add landscape, or discuss what feels unresolved. Larger design critiques bring more of the studio into the conversation.
Architecture and interior design are similarly integrated. When Z Group handles both disciplines, visualization allows decisions about the building, materials, furniture, and interior experience to be seen together rather than as isolated layers.
On the Brush Creek Ranch project, that shared environment extended beyond the firm. Z Group and an outside landscape design company both used D5: the landscape team developed landscape elements while Z Group handled the architectural component.
Rather than visualization belonging to one specialist at the end, it becomes another environment in which different contributors can see the project together.
AI—Without Losing the Architecture
Z Group is beginning to extend this exploratory workflow through AI, but its approach to technology remains consistent: the tool should support the design philosophy, not define it.
That means speed and experimentation are useful only when they help the team understand a place more clearly, explore an idea more thoroughly, or communicate a design without losing the intent behind it.
On a recent project, substantial changes to one wing of a house brought part of the design back into a more conceptual phase. Using D5 Lite, the team could quickly generate different directions for form and materials and use them in conversations internally and with the client.
The team has also used D5 Render’s AI Enhancer to reduce the amount of post-production needed for finished imagery.
But Z Group is cautious about generative AI that changes too much.
Quick AI explorations can be useful, particularly when a client asks to see an alternative immediately. Yet if the output begins changing massing or introducing architectural
decisions that were never designed, it can create confusion rather than clarity.
“Every element of every project has been thought through,” Evan emphasizes.
For Z Group, AI is most valuable when it helps the team explore and communicate ideas without losing the architecture behind them.
WilkinsonEyre’s approach to AI in the design process explores a similar balance.
Designing All the Way Through
Perhaps the clearest change since D5 entered the practice isn’t that Z Group’s workflow has been replaced.
It hasn’t.
The firm still sketches, models, studies physical materials, visits sites, and uses different tools depending on the project.
What has changed is how often visualization can participate in the design process.
“Visualization and rendering is used more often than it was previously to make design decisions,” Evan says.
D5 may have entered the practice through the familiar promise of a better final image. Its more consequential role emerged afterward: making visualization accessible while the architecture is still being worked out.
For a practice that designs all the way through construction, visualization becomes more than a destination. It becomes a way to keep seeing, discussing, and deciding as the project moves forward.
