“Designers must continue to evolve using inspiration from fashion and product design to help the creative mind evolve from business as usual. I think pulling hyper-local arts and culture are more important now than ever. Authenticity is expected and the idea of a contrived composition no longer validates a sense of place. We strive to create something original and timeless in all we do that ultimately gives our owners a better ROI and NOI. We always think of their money like it’s our money. I also think sustainability and innovation with respect to the same is top of mind for most travelers. People want to protect Mother Earth and our value on projects and ownership that share these values.”
LEO A DALY’s Ritz-Carlton Dallas, Las Colinas design featured in Sleeper magazine
“Renovations have touched every corner of the property, with new villas designed to weave together the textures, colours and materials of the Texas landscape. Design elements inspired by indigenous Texas flora and fauna include cool, crisp blues that reflect the opulence of Texas Topaz and the bountiful surrounding lakes, and porcelain tile that nods to the earthy tones of sage and cactus. Touches of leather in warm brown and amber tones evoke the nostalgia of the property’s past as a ranch, with stitching details reminiscent of saddle craftsmanship.”

Adaptive Reuse Saves Embodied Carbon at Repositioned 20 Mass
Mixed-use development features luxury hotel and keeps carbon out of the environment while serving as a cultural hub for Capitol Hill

Our integrated design team excels in complex adaptive reuse projects. The process of redesigning a building to support a new function utilizes our structural engineers, our systems experts, our architects and more. Our teams’ deep knowledge allows them to tackle even the most complex projects. These adaptive reuse projects create far less embodied carbon compared to demolishing and constructing a new building.
A perfect example: 20 Mass, a former federal office building in Washington D.C., reimagined as a vibrant mixed-use development. The adaptive reuse project re-stitched the building into an evolving urban context and created a vital new social and cultural hub for the neighborhood. The resulting building combines ground-floor retail and restaurants to create a vibrant streetscape with an inviting entrance and pedestrian experience, a four-star hotel and Class-A office space with shared amenities between users, a penthouse ballroom and executive suite and an extensive green roof.

The Royal Sonesta Capitol Hill is the 274-key luxury hotel within the building. The project required significant coordination beyond the standard reuse routines. It started with a thorough understanding of the as-built conditions, evolved through complex structural assessments, multiple agency approvals and included implementation of creative modular construction to ensure final delivery and grand opening on time and within budget. The vibrancy of the public spaces, the mix of guests and local community at the street level restaurant, the completely booked conference spaces and Grand Ballroom for the next 2+ years are a testament to a successfully implemented design vision.
This project alone saved 6,900 metric tonnes of CO2eq. That’s equivalent to more than 17.5 million miles driven by an average gasoline-powered passenger vehicle.
The redesign incorporates sustainable and resilient design principles to address ecosystems, water, energy, resources and change. The project prioritizes environmental stewardship by utilizing eco-friendly materials and energy-efficient technologies to minimize its ecological footprint. Rainwater harvesting systems and permeable surfaces manage stormwater runoff, reducing strain on local water resources and mitigating flooding risks. Energy-efficient HVAC systems and lighting reduce energy consumption, lowering greenhouse gas emissions and promoting long-term sustainability. Additionally, the project emphasizes resource efficiency through waste reduction and recycling programs.
The design also anticipates future changes and challenges, such as climate change, by implementing adaptable features and resilient infrastructure. By integrating sustainable practices across all aspects of its design and operation, 20 Massachusetts Ave NW’s redesign demonstrates a commitment to environmental responsibility and resilience, ensuring the longevity and positive impact of the project on both the local community and the wider ecosystem.
