Hello Wood Unveils Revolutionary PEBL Grand Cabins for Urban Rooftops and Forest Retreats

Sayart / Sep 5, 2025

A groundbreaking architectural innovation has arrived in Brooklyn, marking a new era in sustainable modular design. The PEBL Grand, a futuristic cabin created by Hungarian design studio Hello Wood, has been installed on a rooftop overlooking Manhattan's iconic skyline. These sculptural pods represent the cutting edge of small-scale sustainable architecture, seamlessly blending contemporary design principles with advanced technology and luxury comfort features.

Hello Wood's journey began with hosting creative architectural camps where experimental concepts evolved into large-scale public installations. Over the years, the studio has transformed into a comprehensive design and construction company, specializing in unique cabin solutions and glamping accommodations that merge artistic vision with practical architecture. Their breakthrough success came with the PEBL One, a compact workstation cabin that laid the foundation for their expanded vision.

Building upon their initial success, the PEBL Grand represents a significant evolution in modular design. Unlike conventional rectangular cabins, these structures resemble space capsules or naturally formed boulders, hence their distinctive name. The low-polygon, pebble-inspired geometry completely breaks away from traditional box-like modular construction, making them equally suitable for dense forest environments or urban high-rise rooftops.

The construction methodology behind PEBL Grand showcases Hello Wood's innovative approach to sustainable building. Their proprietary construction system, currently under patent protection, utilizes CNC-manufactured CLT (Cross-Laminated Timber) shells layered with high-performance insulation and waterproofing materials. This approach ensures exceptional durability while significantly reducing material waste and assembly time compared to traditional construction methods.

Customization options for exterior finishes are extensive, ranging from natural wood and stone to modern aluminum or reflective mirrored panels. This versatility allows each cabin to either blend seamlessly into its natural environment or make a bold architectural statement. The modular design philosophy extends to functionality, with multiple PEBL units capable of being connected for expanded living spaces.

One of the most compelling advantages of the PEBL Grand lies in its rapid and environmentally conscious construction process. Each unit undergoes complete prefabrication in European facilities and ships either turnkey-ready or flat-packed in standard shipping containers, depending on destination requirements. Upon delivery, installation can be completed in just one day using an innovative ground screw foundation system that eliminates the need for concrete and dramatically reduces environmental impact.

Site preparation typically requires only a few hours, making the entire process fast, predictable, and ideal for projects where construction delays would be costly. This efficiency not only accelerates project delivery but also ensures that every cabin maintains Hello Wood's signature level of craftsmanship and attention to detail.

Despite its compact external footprint, the PEBL Grand delivers the comfort and amenities of a boutique hotel suite. Each unit can accommodate a king-size bed, fully equipped kitchenette, comfortable dining nook, complete bathroom facilities, and even a panoramic sauna for the ultimate luxury experience. Expansive glass openings are strategically positioned to frame spectacular views of the surrounding environment, whether urban or natural.

The versatility of these structures makes them ideal for numerous applications, including glamping resorts, creative studio spaces, exclusive event venues, or private retreats. Their ability to be flat-packed into shipping containers and installed rapidly with minimal site preparation makes them particularly attractive for businesses seeking unique hospitality solutions.

In May, five PEBL Grand units were successfully installed on the rooftop of a Brooklyn entertainment venue, providing performers with a sophisticated backstage retreat while offering unprecedented views of Manhattan's skyline. This project demonstrates how mobile, sustainable, and design-forward micro-architecture can successfully adapt to dense urban environments without requiring heavy construction or causing significant disruption to existing structures.

"The PEBL Grand is the result of years of dedicated development, which has taken Hello Wood all the way from Budapest to New York," explains Tamás Fülöp, one of the lead architects behind the PEBL Grand project. This statement underscores the international scope and ambition behind this innovative architectural solution.

The project represents a significant milestone in the evolution of modular architecture, demonstrating how thoughtful design can create structures that are simultaneously sustainable, luxurious, and adaptable to diverse environments. As urban density continues to increase and environmental concerns drive demand for sustainable construction methods, innovations like the PEBL Grand point toward a future where architecture can be both environmentally responsible and aesthetically striking.
