A Design Story: 7209 Arrowood Road Residence

At Penney Design Group, our work spans both commercial and residential architecture, from national dealership networks to one-of-a-kind homes in our own community.

Each project challenges us to think about how people move, gather, and live in the spaces we create.

The 7209 Arrowood Road residence in Bethesda, Maryland exemplifies a large-scale Mediterranean-modern mansion, on a rare scale: 22,000 square feet spread across four levels. The house is one of the largest in the DC market.

Designing at Scale

When approaching a home of this size, circulation and flow become as important as aesthetics. The residence is organized vertically around a commercial-grade elevator and horizontally through layered gathering spaces that balance openness with intimacy. Our design team was tasked with making a very large home feel warm, livable, and cohesive.

The Entry Experience

The house welcomes guests with a three-story entry gallery at approximately 42’ high. This space is more than an introduction—it sets the tone for the home by blending vertical drama with a refined material palette. Exotic finishes sourced internationally add richness without overpowering the architecture.

Everyday Living Meets Luxury

At the core of the home is a gourmet kitchen with dual islands, supported by both a butler’s pantry and a secondary pantry. The kitchen anchors a sequence of interconnected spaces: a family room that opens directly to a covered terrace, a sunlit morning room, and a glass-lined sunroom. These transitions allow for a natural movement between interior and exterior life.

Integrating Indoor and Outdoor Spaces

The design intentionally extends living areas to the outdoors. A covered terrace with an outdoor kitchen overlooks a landscape that includes a koi pond, swimming pool, and tennis court. These features are not add-ons but integrated elements that reinforce the home’s connection to its site.

Specialized Spaces

The residence layers in purpose-built rooms designed for specific experiences:

A theater room for immersive entertainment.
A library paired with a wine cellar and wet bar for quiet evenings or social gatherings.
An exercise room with direct terrace access, bringing wellness into contact with fresh air and natural light.

Private Retreats

The primary suite is conceived as a retreat within the home, featuring dual walk-in closets, a spa-inspired bath, a sitting area, and a secluded balcony. Each additional bedroom includes its own bath and private access to outdoor terraces, giving family members and guests a sense of autonomy within the larger structure.

Flexibility and Wellness

The upper levels balance productivity and restoration. Two private offices with terraces provide ideal live-work spaces, while a dedicated spa suite with sauna and steam room supports wellness and relaxation. These features highlight how residential design increasingly blurs the line between work, leisure, and health.

Entertainment and Collections

The lower level includes a playroom with a wet bar that opens onto yet another terrace, continuing the theme of indoor-outdoor connection. For car enthusiasts, garaging for seven vehicles plus a carport is seamlessly integrated into the design, reinforcing that architecture can support not only daily living but also personal passions.

Beyond Luxury

What makes 7209 Arrowood Road special is not just its size or amenities—it’s the way those elements come together into a cohesive architectural vision. The design demonstrates how commercial-scale planning and detail can be brought into the residential realm to create a home that is at once grand, functional, and deeply personal. The house is like a resort or a private cultural building compressed into a residence. The combination of a formal arrival, towering internal volumes, carefully arranged mezzanines/galleries, and purpose-built amenity spaces produces an experience that’s more about spatial sequence and material quality than about any single flashy feature.

Sustainability in Automotive Architecture: Trends & Best Practices

July 15, 2025/ Automotive • Sustainability • Trends

A Shift in the Industry

For years, the automotive industry has focused on innovation—smarter engines, sleeker designs, and most recently, a push toward electric vehicles. But there’s another transformation underway, and it’s happening in the buildings that sell and service these cars. Dealership architecture is going green. Not just with flashy buzzwords, but through meaningful design decisions that help reduce environmental impact and support long-term efficiency. At Penney Design Group, we’ve embraced this shift and continue to shape spaces that align with a more sustainable future.

Choosing the Right Materials

Sustainable design starts with smart material choices. Today’s dealerships don’t have to rely on high-impact construction elements to make a statement. Instead, we’re seeing growing interest in using recycled metals, low-VOC paints, reclaimed wood, and durable finishes that reduce the need for frequent replacement.

Green roofing systems, translucent panels for natural daylighting, and advanced insulation methods are becoming more common in our projects, helping to lower energy demand while enhancing the overall aesthetic. These aren’t just “nice-to-have” features—they’re practical investments that pay off over time.

Energy Efficiency that Performs

A major focus of sustainable architecture is energy performance. In our dealership designs, this shows up in everything from HVAC systems to lighting layouts. We design spaces that make the most of natural ventilation and daylight, reducing the need for constant mechanical cooling and artificial light. LED lighting systems are carefully placed to maximize coverage while using as little power as possible.

We also work with engineers to specify high-efficiency HVAC systems that can adapt to different seasons and usage patterns. The result is a dealership that works smarter, uses less energy, and lowers operational costs for the owner.

The Site Matters Too

Sustainability doesn’t stop at the walls of a building. It starts at the site. When we plan a dealership, we look at the bigger picture—how stormwater moves, where sunlight hits, and how vehicle traffic flows in and out. Proper grading and permeable paving help reduce runoff and improve groundwater recharge. Landscaping with native plants cuts down on water use and maintenance.

Thoughtful orientation of the building can make a huge difference in how efficiently it handles heat and light. These early planning decisions are crucial and often determine how well the entire project will perform over time.

Designing for What’s Ahead

The dealerships of today need to be ready for tomorrow. That’s why our sustainable strategies also consider future growth and adaptability. We design service areas that can accommodate electric vehicle infrastructure. We plan mechanical rooms that allow for upgrades down the line. And we create flexible showroom spaces that can be reconfigured as brands and customer experiences evolve.

Sustainability isn’t just about reducing carbon footprints—it’s also about designing smarter spaces that can adapt to change without needing to be torn down or rebuilt.

Our Commitment

At Penney Design Group, we don’t treat sustainability as a separate checklist—it’s part of our process. Whether we’re designing a luxury flagship dealership or a family-run service center, we’re always looking for ways to make it more efficient, more resilient, and more responsible.

We believe the best buildings are the ones that stand the test of time—architecturally, functionally, and environmentally.

Meet The Whitley: New Luxury Residences in Old Town North

July 9, 2025/ Sustainability • Trends

Meet The Whitley: New Luxury Residences in Old Town North

Penney Design Group is thrilled to unveil The Whitley, a new landmark in the heart of Alexandria’s vibrant Old Town North neighborhood. This sophisticated, boutique-style building at 805 N Columbus Street brings 78 elegantly designed condominium residences, 8 of which will be affordable for 100% AMI residents, ranging from studios to three-bedroom homes with terraces, to one of the region’s most sought-after addresses. Developed by PT Blooms with Eichberg Construction as the general contractor, The Whitley is set to deliver in Fall 2025.

Design Vision at Penney Design Group

Our vision for The Whitley began with a clear goal: to bring to Old Town North a distinctively contemporary design which blends a carefully considered modern aesthetic with the character and details of Alexandria’s built heritage; a building which seamlessly fits within the neighborhood yet distinguishes itself by setting a new standard in the area for progressive, forward-looking, high-quality development.

As seen from the corner of North Columbus & Madison streets, The Whitley’s primary massing matched the scale, materiality, and fenestration of the adjacent rowhouses. At the same time, its upper-level setbacks and façade articulations are differentiated using more contemporary materials and treatments. Project-wide, we employed a 12” long brick as a contemporary counterpoint to the 8” standard brick used in traditional rowhouses.

Communal amenities in the project include outdoor terraces on the 5th and 6th floors with defined seating and gathering areas, gas grills, landscaping and city views; a resident lounge with kitchen/bar and fireplace; boutique fitness center; 1st floor courtyard space; bike storage; EV charging; pet-wash; and package room with cold storage for grocery deliveries.

In the residences, the interiors were optimized with open-plan layouts and high ceilings, and accessorized with wide plank white oak flooring, custom micro-shaker cabinetry, quartz countertops, solid-core doors, roller shades, and carefully designed storage solutions.

21st-Century Sustainability

The owners’ mandate to create a one-off residential destination of refined living and contemporary convenience is supplemented by their commitment to the earmarks of 21st-century sustainability: community, wellness, accessibility, and economy of means.

Sustainability today is a broad concept encompassing various environmental, social, and economic components meant to foster better conditions for present and future generations. The Whitley promotes these concepts through the following:

Community

Community begins at The Whitley with a more economically diverse population. Affordable housing units are offered alongside market-rate units. This more comprehensive demographic comes together in The Whitley’s various communal spaces: the resident lounge, the boutique fitness center, the outdoor terraces and courtyards on varying levels, social spaces which promote and foster a sense of belonging and social support.

Wellness

Along with community, individual well-being is nurtured at The Whitley through the thoughtful management of the building’s various environmental features. From the ground level to the rooftop, The Whitley is ecologically engineered to integrate the project’s stormwater management requirements with the climate/health/aesthetic benefits of its greenscape. A green roof, terrace planters, Bio-retention ponds in various locations, and extensive planting throughout the project capture and recycle rainwater, reduce urban heat island effects, improve air quality and enhance biodiversity.

Accessibility

The Whitley’s prime location, a short walk to the historic core of Old Town Alexandria, the Potomac waterfront, and an abundance of cafes, restaurants, and shopping options, offers a pedestrian-friendly urbanism with Alexandria being a model for a unique, ideal urban environment with a small town feel. Just blocks away, the Braddock Metro stop provides connections to Washington, DC and its array of civic, cultural, and business amenities. Recreationally, there are bike and running trails with easy access to DC, Mt. Vernon, and beyond.

Economy of Means

At The Whitley, economy of means is expressed through the thoughtful integration of form, function, and finish—where each design decision serves multiple purposes, and where restraint becomes a tool for elegance. Rather than relying on an abundance of materials or ornate gestures, the building achieves impact through the careful calibration of its elements: a reduced material palette, refined detailing, and efficient spatial planning.

Every brick course, window alignment, and recessed volume was designed to balance aesthetic presence with cost-conscious execution. For example, the use of a singular, elongated 12” brick delivers both a modern identity and an efficient installation process, offering a contemporary rhythm that ties back to local traditions while reducing complexity.

Inside, open-plan layouts maximize livable area and flexibility within a compact footprint, allowing for generous spatial experiences without excess. Shared amenity spaces are consolidated across levels to encourage vertical circulation and offer layered communal experiences without requiring oversized common areas.

Owner/Architect/Contractor Collaboration

The project’s success is a result of thoughtful collaboration among the Owner, Architect, and Contractor. Along with our specialized team of consulting engineers, this collaboration guided the project on a clear and deliberate path through the stringent review processes of the Community and the City of Alexandria’s review board. It continued throughout the project’s various design development, construction documents, and construction administration phases.

What’s Next

Sales milestones: Over 35% of residences sold within weeks of sales launch, with pricing ranging from the $500,000s to $1.9 million.

Construction timeline: On track for Fall 2025 delivery, slated for move-ins in early 2026.

Follow along: Stay tuned for updates on interior finishes, landscape activation, and official opening announcements.

In Closing

The Whitley reflects Penney Design Group’s commitment to delivering thoughtful, sustainable design, meaningful community connections, and impeccable execution—from programming to ribbon cutting. We’re honored to be part of this well-curated collection of homes in Old Town North—welcome home.
