Extending, Refurbishing and Converting Grandstands – Flexible Solutions for Existing Stadiums
Maximum flexibility for existing grandstand and stadium structures
Existing stadiums and grandstands must continuously adapt to new requirements – whether due to increasing spectator numbers, new federation regulations or higher expectations in terms of comfort.
Bender provides tailor-made solutions for grandstand extensions, refurbishments and conversions.
With our modular grandstand system, existing structures can be efficiently optimized without the need for complex new construction.
We ensure full compliance with:
- current VStättVO regulations
- all relevant DIN standards (e.g. DIN EN 13200, DIN EN 13814)
- as well as the requirements of the respective sports federations
The result: a compliant, cost-efficient and future-proof solution for your stadium.
1. Grandstand Extension – Increasing Capacity with Modular Grandstands
Flexible stadium expansion for growing demand
Grandstand extension refers to the targeted expansion of existing stadiums using additional modular seating or standing grandstands.
Typical use cases:
- promotion to a higher league
- increased capacity requirements from governing bodies
- major matches, tournaments or special events
- temporary expansion during high ticket demand
Modular grandstands enable fast and cost-efficient capacity expansion without permanent structural changes.
Your benefits:
- rapid implementation
- flexible dismantling or further expansion
- predictable costs
- optimal use of existing infrastructure
Project Reference: FC Viktoria Köln
Following promotion to the 3rd division, more than 3,500 additional temporary spectator places were installed to meet league requirements and increase stadium capacity at short notice.
2. Grandstand Refurbishment – Upgrading Existing Structures
Efficient modernization of existing grandstands
Grandstand refurbishment focuses on functional and visual upgrading of existing, often aging structures – without the need for complete reconstruction.
The existing structural framework is retained and enhanced or overbuilt using the Bender system.
A key prerequisite is the structural integrity of the existing construction.
Typical objectives:
- improvement of visual appearance
- compliance with current safety standards
- modernization of comfort and equipment
- extension of service life
Your benefits:
- lower costs compared to new construction
- fast implementation
- minimal intervention in existing structures
- sustainable use of existing resources
Project Reference: Ski Jump Stadium Garmisch-Partenkirchen
The existing grandstand was overbuilt and modernized using the Bender modular system – an efficient solution to upgrade the existing infrastructure.
3. Grandstand Conversion – Flexible Adjustment of Seating and Standing Areas
Converting standing areas into seating – and vice versa
Grandstand conversion allows for the temporary or permanent transformation of seating configurations within existing stadiums.
Particularly relevant for international tournaments and federation requirements.
Typical use cases:
- conversion of standing areas into seating (e.g. UEFA/FIFA requirements)
- temporary adaptations for international competitions
- flexible use depending on event type
- adjustment to different target audiences
Your benefits:
- maximum flexibility in usage
- compliance with international regulations
- cost-efficient solution without new construction
- ability to revert quickly to the original configuration

Tailored solutions for your project
Our experienced team will support you in analyzing and optimizing your existing grandstand infrastructure and develop a customized solution – technically sound, economically efficient and precisely aligned with your requirements.
Can an existing grandstand be extended at a later stage?
Yes. Modular grandstand systems are designed with future extensions in mind – whether adding extra rows, side extensions, or new access sections. A structural review of the complete system is required before any extension work begins.
What extension options are available?
Typical extensions include additional rows (upward or sideways), roof covers, wheelchair ramps, extra stair and access structures, commentary boxes, camera platforms, and VIP or hospitality areas.
Do I need a new permit when extending a grandstand?
For permitted temporary structures, any modification to the original configuration generally requires renewed approval. Extensions must be structurally verified and inspected by the authorities. Reputable suppliers will assist with this process.
How long does an extension project take?
Smaller extensions such as a few additional rows can be completed within a few days. Larger extensions involving new roof covers or access structures require more planning and installation time accordingly.
Can a temporary grandstand be upgraded to a permanent structure?
This is generally possible but requires a new classification as a permanent structure under building law, along with the corresponding permits and structural requirements such as a proper foundation and long-term corrosion protection.
