The technical data in this guide combines the TS 825 thermal insulation regulation, the EN 14509 sandwich panel standard and AYD Prefabrik's 2026 field installation records. The performance comparison between sandwich and ABS panels is based on manufacturer technical data sheets.
Prefab office prices vary with area, panel system, equipment package and transport distance. The ranges in this guide are for planning purposes; the post-survey quote should be the basis for final budgeting.
Site office or corporate office? The decision lives in the use case
The first step in a prefab office decision is clarifying the use case. A site office serves throughout the project; the priorities are dismantleability, fast installation and a competitive cost. The insulation package is standard, equipment is simple and durability is essential.
A corporate office is designed for permanent use. Facade aesthetics, interior quality, year-round thermal-acoustic comfort and energy efficiency are top priorities. For the same m², a corporate office costs noticeably more than a site office; but the service life and comfort differ as well.
- A site office focuses on dismantleability and fast installation.
- A corporate office prioritises facade, interior and efficiency.
- The price difference for the same m² depends on package content.
- The decision is made based on lifecycle and intended use.
Panel system: sandwich vs ABS panel comparison
In a prefab office the wall and roof system is defined by the panel choice. Sandwich panels consist of a polyurethane (PUR/PIR) or stone wool core sandwiched between metal skins. The thermal performance of EN 14509-compliant panels depends on panel thickness and core density; 50-60 mm is typical for site offices, while 80-100 mm is preferred for corporate offices.
ABS panels, by contrast, are mainly used for partitions, lightweight interior dividers and compact office units. While they offer cost advantages, they are not preferred as the sole facade panel structurally. The decision is made within the architectural project, thermal targets and the TS 825 framework.
- Sandwich panels are the main facade and roof system.
- PUR/PIR and stone wool cores deliver different performance.
- 50-60 mm for site offices, 80-100 mm for corporate offices is typical.
- ABS panels are used in partitions and compact solutions.
- TS 825 thermal regulation drives the panel selection.
Modularity and mobility: dismantle and reinstall
One of the strongest aspects of a prefab office is modularity. The structure is produced as modular units in the factory, transported to site, offloaded by crane and joined with bolted connections. This setup allows the office to be dismantled and moved to another location when required.
A modular office is especially valuable for companies with changing headcount, temporary factory areas and site management. AYD Prefabrik offers single-storey and two-storey modular offices; two-storey models are structurally calculated and delivered with a site application drawing.
- Modular units are produced in the factory and joined on site.
- Dismantling and reinstallation is possible.
- Single-storey and two-storey options are available.
- Two-storey modules ship with a structural project.
- Scalability supports companies with changing headcount.
Container office vs prefab office: the core difference
A container office is built on a steel chassis matching ISO sea container dimensions and is shipped as a single piece. Width and length are fixed; interior volume and architectural flexibility are limited. The strengths are shipping ease and one-piece installation.
A prefab office, on the other hand, is a system built from modular units assembled on site, with much greater architectural flexibility. Ceiling height, partitioning, facade openings and equipment package are planned per project. Cost and timeline trade-offs differ from a container office; the decision is made based on project scale and flexibility needs.
- A container office is a fixed-dimension single-piece solution.
- A prefab office is modular and flexible.
- Architectural flexibility is markedly higher in prefab offices.
- Shipping and installation are faster for container offices.
- The decision is shaped by scale and architectural needs.
Installation process: from contract to delivery
A standard prefab office project follows these steps: survey and quote, contract, architectural and structural project, production, shipping, on-site installation, interior fit-out and handover. Total duration from contract to delivery is typically 4-8 weeks; site prep (slab/raft foundation, utility connections) runs in parallel.
In the AYD Prefabrik site tracking system, the customer follows production and shipping live. Critical milestones (panel delivery, joinery installation, electrical completion) are flagged in the system. This approach makes plan-actual deviation transparent and simplifies reporting for corporate clients.
- The process flows through survey, contract, production and delivery.
- Standard delivery time is 4-8 weeks.
- Site prep runs in parallel with production.
- The site tracking system ensures process transparency.
- Critical milestones are flagged for reporting.
Total cost: per-m² price, equipment, transport, installation
Prefab office cost combines structure, equipment, transport and installation items. The structure includes the frame, panels, roof, joinery and standard electrical/plumbing infrastructure. The equipment package (AC, heating, kitchen, bathroom, furniture) is added per project or listed as optional.
Transport and crane service depend on distance, module count and site conditions. In corporate offices, facade cladding, interior decoration and energy infrastructure (UPS, generator line) raise the total investment markedly. A transparent quote lists each item separately; AYD Prefabrik quotations follow this approach.
- Structure forms the largest share of the investment.
- Equipment packages are tailored per project.
- Transport and crane scale with distance and module count.
- Corporate offices add facade and interior decoration costs.
- A transparent quote lists items separately.

Frequently Asked Questions
Is a prefab office building the same as a container office?
No. A container office is a single-piece product on a fixed-dimension steel chassis; a prefab office is a modular system of units assembled on site with much greater architectural flexibility. The decision depends on project scale and flexibility needs.
Which panel thickness is suitable for a site office?
A 50-60 mm sandwich panel is typical for site offices. For year-round use or harsh climates an 80 mm panel is preferred. The decision is made within the TS 825 thermal regulation and the project goals.
Which insulation package suits a corporate office?
Corporate offices typically use 80-100 mm sandwich panels with an additional interior insulation layer where required. On the facade, stone wool offers a fire performance advantage over PUR/PIR; the decision is made within the architectural project and the regulation.
Can a prefab office be dismantled and reinstalled?
Yes. Prefab offices with a modular setup can be dismantled and reinstalled at another site thanks to bolted connections and panel joint details. Dismantling and reinstallation is performed by authorised teams following the original installation manual to preserve the modular advantage.
What is the delivery time?
For standard projects, the duration from contract to delivery is 4-8 weeks. When site prep (slab, utilities) runs in parallel with production, total time shortens. Custom architecture and large corporate projects are planned per project.
Which items should be listed separately in a quote?
Structure (frame + panels + roof), joinery, partitions, electrical/plumbing infrastructure, heating-cooling, kitchen-bath equipment, furniture, facade cladding, transport, crane and installation, structural project and, where required, permit and inspection items should each be listed separately.
