In recent years, freeform structures have gained immense popularity in modern architecture, particularly in the design of skylights and glass ceilings. These innovative structures not only enhance the visual appeal of a building but also allow for maximum natural light penetration. In Iran, architects and designers have widely adopted freeform structures, integrating them into both commercial and residential projects.
Initially, international companies, mainly from Turkey, were responsible for the design and installation of these structures in Iran. However, due to rising currency exchange rates and international sanctions, their presence significantly decreased. As a result, local firms stepped in, taking over this specialized field and developing cutting-edge solutions tailored to the Iranian market.
Taj Group: A Leading Expert in Freeform Structure Design
Among the pioneers in this field, Taj Group stands out as one of Iran’s most experienced and trusted engineering firms specializing in freeform skylights and structural glass solutions. By leveraging advanced technology, precise engineering, and innovative design, the company has successfully executed numerous high-quality projects. One of its most notable achievements is the freeform glass dome of the Abrisham Commercial Complex.
Why Choose Freeform Structures?
Freeform structures are an ideal solution for architects and designers who seek unparalleled flexibility in their projects. They allow for customized shapes, making buildings more dynamic and visually striking. Additionally, these structures provide both aesthetic and functional benefits, which is why they are increasingly used in modern commercial spaces.

In the Abrisham Commercial Complex project, a 9-meter-wide hemispherical glass dome was installed, demonstrating the precision and craftsmanship that define Taj Group’s work.
Key Features of the Freeform Structure at Abrisham Commercial Complex
- Advanced CNC Technology – Every structural component was precisely cut using computer numerical control (CNC) technology, ensuring a perfect fit and seamless integration.
- Bolt & Nut Assembly – Unlike traditional welded structures, this freeform skylight utilizes a bolt-and-nut connection system, which enhances accuracy, durability, and ease of maintenance.
- Architectural Impact – The modern and futuristic skylight design creates a striking visual effect, significantly enhancing the building’s overall aesthetic.
- Weather Resistance – Designed with durability in mind, the structure is highly resistant to harsh weather conditions, ensuring long-lasting performance.
The Importance of High-Strength Glass in Freeform Skylights
When it comes to freeform skylights, selecting the right type of glass is crucial for safety, durability, and light control. Taj Group carefully chose high-strength (HS) glass for the Abrisham project, ensuring maximum efficiency and resilience.



Key Benefits of HS Glass in Skylight Structures
- Enhanced Safety – HS glass is engineered to withstand impact and thermal stress, reducing the risk of breakage.
- Optimized Light Transmission – The glass allows natural daylight to flood the space while also minimizing glare and heat absorption.
- Energy Efficiency – By using high-quality glass, the structure helps to regulate indoor temperature, ultimately reducing energy consumption and costs.
- Timeless Aesthetic Appeal – The sleek and modern appearance of HS glass seamlessly complements contemporary architectural styles.
