Mono-Stringer Staircase
A one-of-a-kind three-story home, thoughtfully embedded into the terrain, capturing Lake Austin’s spirit with every level.
Motif Architects approached this unique hillside project with a deep respect for the existing terrain, embracing a 25-foot cut into the landscape left by the previous owner as a guiding design element. Collaborating with three engineers, the team carefully determined the ideal placement of the three-story structure to harmonize with the topography.
With Lake Austin flowing downhill and Mansfield Dam visible from the site, the home was thoughtfully positioned to maximize sweeping views while floating above the carport. This elevated stance not only cleared the canopy line for unobstructed lake vistas but also provided practical storage for boats and trailers—an essential feature for lakeside living.
​
The home’s design balances sculptural elegance with purposeful function, incorporating a custom mono stringer stair, a flexible multi-use room, a dedicated office, spa-inspired bathroom, and a bespoke pool tailored to the site’s contours. To elevate both comfort and safety, a fire suppression system was discreetly integrated throughout the structure. Sustainability was equally prioritized, with features such as solar energy systems, rainwater harvesting, high-performance glazing, and the use of environmentally conscious materials. Every layer of the residence—from engineering to aesthetics—reflects a commitment to site-sensitive design and a modern interpretation of lakeside architecture.


Design Concept
The architectural concept for this residence centers around three foundational functions—storage and hobbies, sleep and fitness, and eat and entertainment—each assigned its own dedicated floor to optimize both utility and experience. Anchoring the structure, the first level operates as a multifunctional base, housing an expansive carport designed to accommodate boat and trailer parking, a compact workshop tailored for hands-on projects, ample storage for outdoor gear, and a fire tank closet to support the NFPA 13-D fire suppression system. By embedding practical infrastructure into the footprint, this level prioritizes preparedness and recreational convenience while reinforcing the home's integration with its lakeside setting.
​
The second floor introduces a more private and restorative environment, designed around well-being and adaptability. The primary suite features generous glazing to welcome in natural light and lake breezes, complementing a spa-like bathroom for daily indulgence. A tucked-away laundry nook offers discreet functionality, while the adjacent flex room provides versatility for the homeowner’s evolving needs. Designed primarily as a home gym, this space easily transitions into a second office or guest bedroom, offering a dynamic buffer between retreat and routine.
​
Crowning the residence, the third floor is a celebration of landscape and leisure. Purposefully oriented toward Lake Austin and the surrounding hillside, this level includes a panoramic family room, a streamlined kitchen with walk-in pantry, and a dedicated office that blends productivity with lake-inspired calm. With direct access to a custom pool, the indoor-outdoor experience is seamless, encouraging year-round enjoyment. This floor captures the essence of lakeside living—not just through architecture, but through framed moments of view, connection, and hospitality.


Custom Mono-Stringer Stair
Modern mono stringer stairs offer a striking blend of sculptural simplicity and engineered elegance. At the heart of the design is a custom-fabricated HSS tube steel spine, providing both the visual centerpiece and the structural backbone of the staircase. The open riser configuration enhances the sense of light and space, allowing natural light to filter through and contributing to an airy, contemporary aesthetic. Solid wood treads rest securely atop precisely engineered steel plates, balancing industrial precision with warm organic materiality. Sleek wire guard rails trace the stair’s silhouette, offering minimalist protection while reinforcing the clean, streamlined appearance.
​
The stair was meticulously designed and engineered by a licensed structural engineer, ensuring safety and performance without compromising design integrity. Integrated stair tread lights illuminate each step with subtle sophistication, adding both visual drama and functional clarity—especially during evening hours.
This harmony of steel, wood, and light makes the mono stringer system not only a practical circulation element but a focal point of foyer.





Engineering and Coordination with the City of Austin
Designing for this particular site came with a host of complexities from day one. Fortunately, our prior experience with another project on the same street equipped us with a working knowledge of the local nuances—slope maps, fire flow testing, Urban Wildlife Interface, and the Lake Austin Overlay were familiar hurdles. However, the added challenge of managing two parcels with differing zoning regulations elevated the level of coordination and technical scrutiny required. These site constraints influenced nearly every early decision and prompted a highly collaborative effort to ensure compliance and clarity throughout the design process.
​
In partnership with the owner, we assembled an experienced team of engineers and consultants to navigate the technical and jurisdictional intricacies. A geotechnical engineer initiated the process with soil test borings to produce a comprehensive report, which informed the structural design parameters. A surveyor was brought in to tackle easement releases, access road planning, and utility coordination. Concurrently, we worked hand-in-hand with a structural engineer who design foundational elements, framing, retaining walls, and pool. The septic system design fell under the scope of an OSSF specialist, while a dedicated pool designer handled layout and equipment specifications. Drainage solutions and retaining wall placement were orchestrated by a civil engineer, rounding out the technical team.
As part of the permitting phase, we also engaged a permit expediter to interface with the City—an essential move considering the dense web of code requirements and procedural checkpoints. To minimize delays and streamline reviews, the owner approved the $5,000 permit expedition fee, which unlocked an elevated tier of city coordination. Before advancing deep into schematic design, we scheduled a series of review meetings with city officials to confirm alignment with planning, zoning, and overlay restrictions. This strategic engagement upfront proved critical in reducing rework and building momentum.
Altogether, this project demanded far more than creative architecture—it required orchestrating a synchronized effort among multiple disciplines and stakeholders. For Motif Architects, the process extended well beyond design, involving extensive research, documentation, coordination, and jurisdictional navigation. It’s a testament to the rigor and resilience needed to transform a challenging site into an inspiring home, where thoughtful planning and perseverance became just as vital as the aesthetic vision.



Detailed BIM Model
and Documentation

Building Information Modeling (BIM) technology offers numerous advantages for architects when designing and documenting custom homes. One of the primary benefits is the ability to create highly detailed and accurate 3D models of the entire project. This level of precision ensures that all aspects of the design are thoroughly planned and visualized, reducing the likelihood of errors and omissions during construction. With BIM, architects can simulate various design scenarios and make informed decisions, ultimately leading to better design outcomes and higher-quality custom homes.
​
Another significant advantage of using BIM technology is its role as a powerful communication tool. During the design phase, BIM models provide a clear and comprehensive visual representation of the project, making it easier for clients to understand and engage with the design. This transparency fosters better collaboration between architects, clients, and other stakeholders, ensuring that everyone is on the same page. Additionally, during the construction phase, BIM models serve as a reference point for contractors and builders, facilitating smoother coordination and reducing misunderstandings and delays.
Furthermore, BIM technology enhances the documentation process by integrating all project data into a single, accessible platform. This centralization of information streamlines the creation of construction documents, specifications, and schedules, improving overall project management. The detailed documentation generated through BIM helps ensure that the construction process adheres to the original design intent, maintaining the integrity and quality of the custom home. In summary, the use of BIM technology by architects not only improves design accuracy and communication but also enhances the efficiency and reliability of the entire construction process.
