Reimagining a Downtown Corner: 550 West C Street

Zeek Magallanes, MLA, ASLA
Studio Team Leader, Project Manager

The 550 West C Street project was a three-phase exterior and interior renovation located in the heart of downtown San Diego. The project aimed to upgrade the interior amenity offerings for tenants, enhance the streetscape for pedestrian safety, as well as enhance the entry plaza to provide smart technology space for outdoor meetings and a small café to activate the location for tenants.

At the start of the project our client, Cushman & Wakefield, assessed its surrounding sidewalk condition and determined that the uplift had been caused by existing mature trees that had not been planted properly. The improper design had created a safety hazard to those passing by not paying attention—causing multiple trip incidents. These issues highlighted the importance of bringing new design thinking to the much-needed public right-of-way renovation. In addition to the right-of-way trip hazards, the large entry plaza at the front of the property aged considerably and had become a space that was rarely used by its tenants, not reflecting the original vision for the space.

Our creative endeavor in the project was in collaboration with Gensler, specifically under the direction of Chris Bord and Matthew Bourne. Under Gensler’s direction, our design team explored several design iterations, engaged the client on a regular basis, and found a solution that aligned with the client’s vision and budget. At McCullough, our mission is to infuse grit, soul, and style into every project, principles that guided the transformation of this plaza.

Through careful selection of materials, we sought to express the site’s “grit” by reflecting its downtown urban context through durability, simplicity, and longevity. The ‘soul’ of the project stemmed from the client’s desire to ensure the pedestrian zone around the building would be inviting and safe for everyone—those coming and going, as well as community members simply passing by. It also involved reactivating the empty plaza, which serves as the first impression for anyone entering the building. Finally, the ‘style’ of the project was essential to align with the client’s overall aesthetic: refined, classic, clean, and professional.

Early in the construction phase, representation of the property changed over to JLL, and was led by Aljon Medina, Project Manager, San Diego Market. JLL’s ability to acquire strategically placed and high value assets was on full display during the project build-out. Every phase of the implementation was curated and informed by their management team. This enthusiasm trickled down to the design team and reinvigorated our desire to create something truly special and valuable to the City of San Diego.

As the general contractor, BYCOR ensured effective communication was maintained among all stakeholders and relayed updates from JLL to the design team as needed. Their ongoing attention to detail and ability to address unforeseen on-site discoveries contributed to a smooth and efficient installation.

Today, visitors to the site experience a fully renovated streetscape featuring healthy, vibrant street trees supported by proper infrastructure installed at the time of planting. At the main entrance, a large plaza welcomes guests with various seating options and a visually appealing paving pattern that enhances the ground plane. Pavilions flank the main entrance on both the west and east sides. To the west, visitors will find a custom multimedia outdoor meeting space designed by the team at Gensler; while to the east, an outdoor café offers tenants warm drinks and healthy snacks. Surrounding both pavilions, McCullough’s thoughtful planting design is showcased in raised planters that cradle each structure. These planters feature a curated mix of shade-tolerant shrubs with seasonal interest, artfully arranged beneath the expansive canopy of mature trees. Fronting the planters are concrete benches topped with sustainable hardwood slats. To further enhance the experience, the entire plaza is buffered from the nearby trolley line by a row of densely planted, movable raised planters—bringing a strong sense of cohesiveness and unity to the site.

Arid Landscapes: Between the Ancient and the Emerging

Polina Karake, MSID, Int’l ASLA

Written by Polina Karake, MSID, Int’l ASLA, Associate

Nothing in the desert is as it seems – it is a masterpiece of life, resilience, and adaptability. Emptiness is not truly empty, but a hidden world of vitality. Dryness is only temporary; every drop of water is measured, and every form of existence adapts accordingly. The desert is not silence, but a quiet that invites introspection – a search for harmony between human and nature, between the ancient and the emerging.

Arid landscapes often evoke images of harsh, barren environments. However, these deserts hold untold richness and potential. Landscape architecture in the desert is not just about overcoming challenges; it is about working with the land's unique conditions, creating spaces that are both functional and harmonious. The design of desert landscapes requires an innovative, sustainable approach that respects the delicate balance between nature and development, while also honoring the cultural and historical context of the region.

In this article, we explore the principles, challenges, and opportunities of landscape development in arid environments, where ancient traditions meet emerging technologies and new design strategies. By integrating these elements, we can create resilient, beautiful, and functional spaces that endure the test of time.

Understanding the Desert

Deserts span every continent, covering about one-fifth of Earth’s land and supporting over a billion people. Defined by extremes—scorching days, chilly nights, rare rainfall, and intense winds—these landscapes are shaped by sun, sand, and sudden water. Though precipitation averages under 10 inches annually, flash floods and high-speed winds constantly reshape the terrain. At the same time, Deserts are rapidly expanding due to desertification, especially in Africa, where over 60% of the population lives in arid or semi-arid regions. As land becomes unproductive, farming communities are forced to leave. Many end up in cities, displaced and unemployed, with few opportunities. In some areas, this growing strain on resources can spark conflict over land, water, and food.

Plants in arid regions have evolved ingenious survival strategies. Many grow far apart to reduce competition, while others develop deep taproots or shallow, widespread systems to capture water. Thorns serve both as defense and as shading tools. Unlike plants in temperate climates that rest in winter, desert species often go dormant in summer. Their ecology follows a cycle of disturbance and renewal—fires or droughts trigger seed germination, and successive plant generations enrich the soil, each laying the groundwork for the next.

Designing with the desert means working within these rhythms—embracing dormancy, succession, and resilience.

Desert civilizations have long mastered this balance. Nomadic life, breathable fabrics, and architecture attuned to the elements reflect generations of adaptation. Courtyards, thick walls, and wind towers cool interiors naturally, while narrow streets and overhangs provide essential shade. Built from local materials, traditional desert buildings absorb and release moisture to temper indoor climates. These passive strategies offer timeless lessons in sustainable design: climate responsive, resource-savvy, and deeply rooted in place.

Challenges and Design Principles of Desert Landscapes

Desert environments demand smart, resource-conscious design. Water scarcity, nutrient-poor soils, extreme temperatures, and rapid urbanization pose ongoing challenges. Xeriscape with native, drought-tolerant plants reduces irrigation needs, while smart systems using sensors and weather data ensure efficient water use. Greywater recycling, rainwater harvesting, permeable paving, bioswales, and underground cisterns work together to retain and reuse water on-site.

Soils in deserts often face salinity, erosion, and nutrient loss. Regenerative methods like composting, mulching, and adding biochar (black carbon produced from biomass sources) possibly may improve fertility and water retention. Wind erosion is countered with ground covers, windbreaks, and stabilizing vegetation.

Designers must also create thermal comfort in harsh climates. Shaded spaces, canopy trees, pergolas, and evaporative cooling features—like fountains or reflective pools—help lower ambient temperatures. Light-colored materials reduce heat absorption, and even green roofs and planted walls can be adapted with drought-resilient species and efficient irrigation.

As desert cities grow, preserving ecosystems and biodiversity becomes increasingly urgent. Integrating traditional wisdom with modern technology fosters resilient, culturally grounded design. Passive cooling techniques—such as thick adobe walls, courtyards, and wind towers—can be paired with solar energy and smart water systems for sustainable performance.

Finally, low-impact construction with local, natural materials reduces emissions and reinforces regional identity. Modular systems, minimal grading, and off-site fabrication minimize site disruption while maximizing resource efficiency.

Desert Aesthetics – Power in Simplicity

When people think of desert aesthetics, many imagine a monochromatic, dull, even lifeless palette—sand to the left and sand to the right. But a deeper look reveals a rich and intensified visual experience: sunsets and sunrises glow more vividly, sands shift between golden, red, and white hues, mountain layers form intricate textures, the sky appears bluer, the air crisper, shadows are sharper, shapes more defined, and the night sky bursts with countless stars.

As we approach the design of a desert landscape, we must do more than simply adapt to its harsh conditions—we need to listen to its unique qualities and weave them into a unified spatial fabric. A well-designed desert environment brings together essential human needs, ancient traditions, and contemporary aesthetics to create places that are both functional and deeply moving—spaces that reflect the true spirit of the desert.

Desert landscape design offers a unique opportunity to celebrate cultural identity and the inherent beauty of the environment. Designing with local traditions and community values in mind helps create spaces that resonate with the people who use them. Incorporating regional customs, art, and architecture—not only in form, but in materiality and craftsmanship—ensures authenticity and emotional connection.

The minimalist beauty of the desert lies in its simplicity. Designers often work with the natural elements of light, texture, and color to create subtle, elegant compositions. The vast, open landscapes lend themselves to designs that embrace calm, balance, and quiet strength—expressing the desert’s serene yet powerful character.

Public spaces in the desert serve not only as functional areas but also as spaces of reflection, gathering, and community bonding. Thoughtfully designed courtyards, gardens, and shaded social areas allow for interaction with nature and with one another—encouraging a deeper connection to nature through the land and culture.

Insights and Case Studies: Learning from the Desert working with it

Desert landscape architecture should adapt the specific character of the desert in which it is rooted. Often, it is "dry" in appearance, with little to no vegetation, blending seamlessly into its surroundings or framing the natural landscape rather than altering it. In many cases, the landscape design acts as a subtle yet powerful complement to existing or new architecture, elevating the presence of built forms by harmonizing with the desert’s raw beauty.

Across regions like the UAE, Israel, Arizona, Baja California, and California’s Colorado Desert, designers have drawn inspiration from both ancient desert traditions and cutting-edge technologies. These cross-regional projects reveal a shared understanding: success in desert landscapes lies not in fighting the environment, but in working with it.

Another compelling example of this harmonious blend between tradition and technology is the 3D-printed pavilion designed by the Dubai-based architecture studio MEAN (Middle East Architecture Network), situated in the breathtaking desert landscape of Wadi Rum, southern Jordan. Inspired by the ingenuity of the mobile architecture of the local Bedouins, this pavilion serves as a welcoming gesture to visitors entering the desert, seamlessly integrating architectural innovation with the spirit of place. Drawing further inspiration from the ancient aesthetics of the Mashrabiya—a traditional latticework screen used in Middle Eastern architecture to filter sunlight and allow air circulation—the pavilion reinterprets these forms through digital fabrication techniques. Its perforated, organic structure not only creates a shaded, serene space but also collects water and supports a localized microclimate, offering respite from the desert’s harsh conditions. Desert trees and shrubs are planted at the center of the pavilion to help regulate the atmosphere within, enhancing thermal comfort and air quality. The pavilion’s funnel-like forms also act as lightwells, capturing natural daylight and channeling it into the interior, creating a luminous, welcoming environment.

One striking example of desert-responsive design is a landscape project by McCullough in Las Vegas, where thoughtful planting and spatial composition celebrate the desert’s unique beauty. Succulents in sculptural formations form a resilient and water-wise planting palette, showcasing texture, color, and structure across the arid terrain. Towering date palms cast delicate, lace-like shadows across the ground, softening the sun's intensity and creating moments of shelter and rhythm within the landscape. The design not only embraces the harsh conditions of the Mojave Desert but transforms them into an immersive, elegant experience rooted in place.

In the heart of Israel’s Negev Desert, Braudo Maoz Landscape Architecture crafted a visionary project within Makhtesh Ramon (Ramon Crater) National Park, known as “The Colors of Ramon.” This initiative exemplifies how landscape architecture can celebrate geology, ecology, and visitor experience while preserving the delicate desert terrain. What makes the project stand out is its ability to translate geology into experience. Trails are designed to guide visitors through a color journey, showcasing the area's stratified rock layers and endemic flora. Signage and materials are understated, directing attention to the surroundings rather than themselves. Even seating and shade structures appear to emerge organically from the terrain, inspired by natural rock forms.

The Future of Desert Landscape Architecture

As climate change accelerates, the role of desert landscape architecture becomes increasingly critical. Designers must now look beyond present-day challenges and envision resilient environments capable of adapting to shifting climates, prolonged droughts, and extreme weather events. This future-forward approach calls for landscapes that not only survive in arid conditions but actively mitigate desertification and support the health of delicate desert ecosystems.

Landscape architects have a vital role in shaping the future of arid regions, developing strategies to manage water scarcity, restore degraded soils, and strengthen biodiversity. These efforts include designing systems for capturing and reusing water, selecting plant species that can withstand harsher conditions, and promoting regenerative land management practices that repair rather than exploit natural systems.

Equally important is a focus on human-centered design. In rapidly urbanizing desert areas, the need for wellness-oriented outdoor spaces is growing. Future landscapes must provide thermal comfort, psychological relief, and social connectivity. Shaded walkways, cooling zones, urban oases, and public gathering spaces are essential components of a livable desert city. By creating equitable and accessible green spaces, designers can ensure that these environments serve diverse populations—not just economically or socially privileged groups.

Looking ahead, predictive planning and futureproofing are essential to successful desert design. One effective approach is the Bioclimatic-Zones Concept, which organizes outdoor spaces into zones based on specific climatic goals, such as Shelterbelt, Oasis, Inner Garden, Parking and roads etc. Each zone is shaped by targeted landscape decisions—such as types and densities of vegetation or the inclusion of water elements—to achieve desired thermal effects. These zones are defined by detailed climatic conditions and evaluated based on their impact on the microclimate. By anticipating the environmental role of each element, this strategy forms the backbone of site planning in arid regions.

Landscape design decisions are guided by the expected climatic outcomes of each zone. The process begins with a thorough site inventory and analysis, identifying opportunities for bioclimatic interventions. These informed zones create relative differences in microclimatic comfort and resilience, forming the basis for the final site composition.

Conclusion

The desert, often seen as barren and unforgiving, is in fact a powerful teacher. It reveals timeless lessons about resilience, patience, and the art of thriving with less. In its silence and extremes, the desert reminds us of that strength often lies in stillness, and beauty in simplicity. For landscape architects, it challenges us to design with humility, ingenuity, and deep respect for the land.

Looking forward, the vision for desert landscapes must be one that honors ancient knowledge while embracing modern innovation. By weaving together tradition and technology—earth-based building methods with smart irrigation, or cultural symbolism with adaptive design—we can create spaces that are not only sustainable but have soul. Desert landscape architecture is, at its core, a continuous dialogue between the past, present, and future.

It is a discipline that asks us to innovate without erasing history, to build without breaking the land, and to design spaces that restore balance—ecologically, socially, and spiritually.

In this dialogue, the desert is not a limitation but an inspiration.

But the poetry of the desert is accompanied by a hard truth. It presents numerous constraints across all aspects of architectural and landscape development—from the lack of fertile, permeable soil and severe soil erosion; too harsh climate conditions, strong winds, water scarcity, and flash floods. These challenges raise difficult questions about the feasibility and legitimacy of any landscape project. What plant palette should be used? How should the irrigation system be managed, and for how long?

Resilience and grit are essential to meet these challenges. In the end, it is we who must adapt to the desert—not the other way around.

The desert serves as a model for practical, resource-efficient design—and so should the landscapes we create. They must adapt to extreme conditions and limited resources, while still offering a unique aesthetic—one that reveals the quiet beauty behind the sandstorm, invites patience, and aligns us with the rhythms of the land. As the desert greets the sun each morning, so too can our work illuminate new paths—physically, emotionally, and spiritually—guiding us through the sands of time.
