Custom Planters for Architects and Designers

Urban Pot is the preferred partner for architects across North America in designing high-end custom planters. We turn complex concepts into structural realities with expertise in marine-grade aluminum, Corten steel, fiberglass, and high-performance concrete, ensuring seamless architectural integration and proven durability in the North American climate.

Why Is Urban Pot the Reference for Landscape Specifiers?

For architects and designers, a planter is a structural, safety, and aesthetic element subject to strict standards. At Urban Pot, we understand your needs for CAD files, structural loads, and material durability.

Materials Expertise for Climate Resilience

As a North American leader, we have developed expertise in thermal and mechanical properties to ensure durability through freeze-thaw cycles in Quebec and Canada.

Marine grade aluminum (5052-H32): Lightweight and fully corrosion-resistant, ideal for roof terraces.
Corten steel: Develops a self-protective patina, offering a durable and natural appearance.
Fiberglass: Provides the look of solid materials with 75% less weight, making it suitable for structures with limited load-bearing capacity.
Resin (polyethylene): Highly impact- and UV-resistant, offering an economical and versatile option for high-traffic areas.
Concrete: Delivers maximum stability and a timeless, mineral aesthetic.

Engineering and Design Expertise

An Urban Pot planter is a comprehensive plant management system. Our engineering team incorporates features not found in standard products:

Advanced drainage management: We design custom raised floors or drainage holes to prevent water stagnation and safeguard building structures.
Internal structural reinforcements: For large or monumental formats, we add concealed reinforcements to prevent wall deformation from saturated soil pressure.
Integrated thermal insulation: Upon request, we install high-density insulating panels within the walls to extend the growing season and protect roots from frost.

Seamless Integration into Your Design Process

We understand that your time is valuable. Our support service for design professionals aims to simplify your operations.

Technical Support and Specifications (CSI)

We supply all required technical details for your quotes. Urban Pot anticipates potential constraints, such as integrated irrigation systems, internal thermal insulation, or anchor points for public safety, to help prevent issues during construction.

Unlimited design flexibility

Your vision should not be restricted by a catalogue of standard products.

We accommodate complex shapes, including curves, irregular angles, and extra-large formats.
Custom finishes are available, including ultra-resistant powder coating with an unlimited color palette based on the RAL color chart.
We offer integration of LED strips and wooden benches to create complete living spaces.

Durability, Circular Economy & Environmental Compliance

By 2026, regenerative design will become a structural requirement. Urban Pot is aligning its manufacturing processes with the strictest sustainable building standards to facilitate obtaining LEED v4.1 and BOMA Best credits.

A low-impact materials strategy

Our approach is based on life-cycle assessment (LCA) for each product.

100% recyclable metals: We favour aluminium that can be reused indefinitely without loss of mechanical properties.
Local manufacturing and short supply chain: Production in Canada significantly reduces GHG emissions related to transportation and supports the regional economy.
Eco-design and longevity: Protecting the environment means manufacturing products to last 30 years instead of 5. Our VOC-free electrostatic powder coating finishes preserve your assets without emitting toxic particles.

Expert advice: For roof terraces above the 10th floor or in coastal areas, we recommend 5052-H32 marine-grade aluminum. Its resistance to extreme wind pressure and salt oxidation limits premature replacements and optimizes the building's carbon footprint over 50 years.

Technical Expertise: Frequently Asked Questions from Professionals

Why is Urban Pot considered the best reference in North America for custom-made products?

Our strength is the combination of precise craftsmanship and advanced industrial capabilities. Urban Pot offers full customization of dimensions, shapes, and finishes while complying with building codes and structural constraints. Our reputation comes from the exceptional durability of our products in extreme weather conditions in Canada and the United States.

What types of finishes do you offer to guarantee corrosion resistance?

For our aluminum planters, we apply a powder-coated, oven-baked finish after rigorous pretreatment. This finish provides optimal protection against UV rays, scratches, and road salt. For an organic look, Corten steel develops a natural oxidation layer that prevents internal corrosion and ensures long-term, maintenance-free durability.

How do you facilitate the integration of planters into architects' plans?

We work closely with your design team. We provide detailed estimates and technical specifications and can integrate your CAD or BIM files. Every detail, from drainage and thermal insulation to anti-theft anchor points, is planned before production to prevent unforeseen issues during installation.

Are your products suitable for LEED certifications and sustainable buildings?

Absolutely. Urban Pot solutions earn LEED credits through recyclable metals and local manufacturing, thereby minimizing transportation emissions. The durability of our planters extends the lifespan of materials, supporting sustainable design and reducing the long-term carbon footprint.

Do you offer customization options for lighting and irrigation?

Yes, each planter can be pre-drilled or factory-adapted for drip irrigation systems, water reservoirs, or LED lighting conduits. We also offer recessed bases to create a floating effect or conceal wiring, ensuring a neat, professional finish.

Technical Glossary

5052-H32 aluminum is selected for its corrosion resistance in saline and industrial environments, as well as its favorable strength-to-weight ratio. This alloy is commonly specified where durability and reduced weight are required.
Dead load refers to the combined weight of the planter and fully saturated soil. Fiberglass construction can reduce this load by up to 75 percent compared to concrete, enabling installations in locations with strict weight limitations.
A root thermal bridge occurs when heat from the planter wall transfers into the growing medium, potentially stressing plant roots. High-density insulation systems can be integrated to stabilize substrate temperature and support long-term plant health.
Powder coating is a solvent-free, thermosetting finish that forms a durable barrier against moisture, UV exposure, and urban pollutants. Proper application is essential to maintain finish quality over time.
