High-Specification Modular Site Offices for Portsmouth
As Portsmouth continues to see significant investment in both residential and naval infrastructure, the demand for high-quality on-site accommodation has never been higher. Adacon supplies the P600 modular building system, which is engineered to provide a comfortable, long-term working environment for site teams. Unlike temporary containers, our units feature a permanent-feel internal finish with plastered walls, LED lighting, and high-performance insulation.
Typical Configurations and Floor Space
The flexibility of the P600 system allows site managers to scale their office space according to the headcount and project duration. Modules measure approximately 13m² and can be linked to create expansive open-plan layouts or partitioned zones.
- Single Module (13m²): Ideal for small residential developments or restricted urban sites in central Portsmouth where space is at a premium. Suits 1-2 desks plus a meeting table.
- Two-Module Link (26m²): A popular choice for mid-sized contractors. This configuration allows for a dedicated office space alongside a small canteen or document storage area.
- Four+ Module Complexes (52m²+): For major infrastructure projects, these units can be stacked two storeys high to save ground space. These often include integrated modular toilet blocks and dedicated boardrooms.
Standard Specifications
Every building we deliver to the Portsmouth area is built to a consistent, high standard. We do not sell converted shipping containers; our buildings are purpose-built steel frames designed for occupancy. Standard features include:
- Fully insulated walls, floor, and roof for year-round thermal efficiency.
- Double-glazed uPVC windows and secure external doors.
- Internal finishes including plastered and painted walls, laminate flooring, and skirting.
- A complete electrical package with LED ceiling panels and multiple socket points.
- Exterior cladding in a range of professional colours to suit corporate branding.
Indicative Pricing for Portsmouth Projects
Pricing for a P600 site office typically ranges between £16,000 and £60,000. The final cost depends on the number of modules, the complexity of the internal layout, and any optional extras such as air conditioning, kitchenettes, or modular shower blocks for site welfare.

Delivery and Logistics in Portsmouth
Portsmouth’s unique geography—being largely situated on Portsea Island—presents specific logistical considerations. Our delivery teams are experienced in navigating the M27 and A27(M) corridors, as well as the busy arterial routes like the A3 London Road. For sites in more congested areas, such as Southsea or the city centre, we coordinate closely on crane access and road permits.
It is the customer's responsibility to ensure a level, prepared base is ready before the modules arrive. We also require clear vehicle access for the heavy goods vehicles (HGVs) used for transport. Once the modules are craned into position, your local qualified contractors will need to handle the final electrical connection to a consumer unit and any necessary drainage for units with plumbing.
Lead Times and Reliability
Speed of deployment is a primary reason contractors choose Adacon. While traditional construction can take months, our P600 modules are manufactured in our specialist facility and delivered in weeks. We also maintain a selection of Ready to Order stock units for even faster turnaround, which is critical for projects with immediate start dates or unexpected site expansions.
Local Authority and Planning
While modular site offices are often considered temporary structures, their placement may still be subject to local regulations. Rules regarding planning permission and building control vary depending on the site location, duration of the project, and the proximity to existing structures. We advise all Portsmouth customers to consult with Portsmouth City Council or the relevant local authority planning department early in the procurement process to ensure compliance.
