GREENHOUSES, Orangeries

GARDENIS Aluminium Greenhouses, Orangeries and Garden Rooms - Designed for Northern European Living

Since 2007, Gardenis UAB has been offering high-quality aluminium greenhouses, orangeries, garden rooms, and other light-transparent outdoor structures to clients across the Baltics, Nordics, and wider Europe.

Gardenis structures are created for those who value reliable engineering, refined aesthetics, and multifunctional use - whether for plant cultivation, relaxation, hosting, or extending both everyday living or business closer to nature.

We offer more than a greenhouse - we create adaptable infrastructure for a wide range of functions and purposes. How it is used today, and how it evolves over time, is defined entirely by you - our customers.

Durability, Comfort, and Timeless Design

Engineered for demanding Northern European weather, Gardenis greenhouses combine robust aluminium construction with high-quality, light-transparent glazing materials in an elegant, balanced design. Tall side walls and optimised profiles create a spacious, comfortable interior while ensuring long-term stability and performance.

Glazing options include 4 mm tempered glass or 10 mm twin-wall polycarbonate - both selected for durability and long service life. Glass offers maximum light transmission and a clean, classic aesthetic, while polycarbonate provides enhanced insulation and impact resistance. A hybrid solution is also available, combining both materials within a single structure, allowing clients to optimise performance and aesthetics.

Efficient production processes and well-developed manufacturing capacities enable short, reliable lead times while maintaining excellent value. Despite this level of quality and engineering, Gardenis structures are offered at a competitive price.

Flexible Design for Every Space

We offer a wide range of models, sizes, and configurations to suit both compact gardens and larger landscapes.

Key options include:

• A wide range of standard and custom dimensions and architectural forms,
• Mill finish or powder-coated aluminium (RAL Classic palette; Qualicoat),
• Sliding or hinged, single or double doors, and wide roof or wall windows, with flexible positioning and quantity for efficient access and ventilation,
• Accessories, including shelving, plant support systems, automated ventilation, and pet-friendly and other practical solutions,
• Installation on ground, terrace, wall-mounted, or existing foundations.

Quality Without Compromise - Since 2007

Since 2007, Gardenis has been a trusted partner across the Baltics, Nordics, and wider European markets, recognised for consistent quality, professional service, and long-term reliability.

Rather than focusing on volume production, our priority is to ensure that every structure meets the highest expectations in functionality, durability, and design. Attention to detail, structural integrity, and refined finishing define every project we deliver.

Each greenhouse is produced with precision, using high-grade, certified raw materials sourced from trusted suppliers and meeting the highest international standards. Our processes are certified under EN 1090-1, EN 1090-3, ISO 9001:2015 and ISO 14001:2015.

Engineered in the Baltics for Nordic Climates

Greenhouse culture is deeply rooted in Lithuanian / Baltic traditions. While the region’s fertile soil supports a wide variety of plants, the short warm season and frequently changing weather have long created a need for protected growing environments. As a result, greenhouses have for decades been an essential part of everyday household life - used to grow food or decorative plants. Today, greenhouses remain an integral part of most family gardens, driven by the growing need for fresh, safe, home-grown food, experimentation with a variety of plants, and the desire for a calm and comfortable space in the garden for different activities and hobbies - further strengthening the demand for Gardenis greenhouses and orangeries.

This long-standing experience shapes the entire GARDENIS team’s understanding of what a truly good greenhouse must be: engineered to perform reliably, provide comfort, and remain structurally sound and visually attractive over decades of use.
