Modern Modular Buildings in Portsmouth
Adacon supplies the P600 modular system, a high-specification steel-framed building produced in our dedicated facility and delivered across the UK, including Portsmouth and the wider Solent area. These are not wooden sheds or converted containers; they are robust, permanent structures designed for year-round use. Each module provides approximately 13 m² of internal floor space and can be used as a standalone unit or combined to create larger, multi-room layouts.
For those looking for garden rooms, the P600 provides a superior thermal envelope, ensuring the building remains warm in winter and cool in summer. This makes it an ideal choice for the coastal climate of Hampshire, where durability and insulation are paramount.
Typical Configurations for Portsmouth Gardens
The flexibility of the P600 system allows it to adapt to various site constraints found in the city. Depending on your available space and intended use, you can choose from several configurations:
- Single Module (13 m²): Perfect for a spacious garden office or a private treatment room. Its footprint is often easier to accommodate in smaller urban gardens.
- Double Module (26 m²): A popular choice for home gyms or larger studios, providing two distinct zones or one large open-plan space.
- Four+ Modules (52 m²+): Suitable for larger plots, these configurations can serve as multi-functional garden annexes or expansive professional workspaces.
High-Specification as Standard
Every P600 module is delivered with a complete internal fit-out, reducing the need for local contractors. Our standard specification includes:
- Steel-frame construction for long-term structural integrity.
- Insulated walls, floor, and roof for high thermal efficiency.
- Internal finishes: plastered and painted walls, laminate flooring, and LED lighting.
- Double-glazed uPVC windows and external doors.
- Exterior cladding in a choice of colours, which can be selected wall-by-wall via our 3D tool.
- Multiple electrical sockets and a pre-installed consumer unit.
Optional extras include internal WC and shower compartments, kitchenettes for self-contained use, and air conditioning for precise climate control.
Indicative Pricing for Portsmouth Projects
Project costs vary based on the number of modules, specific configuration, and optional upgrades. For garden use, indicative prices typically range from £15,000 to £35,000. This range covers the modules themselves and the internal fit-out. It is important to note that delivery, groundworks, and final utility connections are quoted separately to ensure accuracy for your specific site conditions.
Delivery to Portsmouth and Hampshire
Portsmouth presents unique delivery considerations. Most units arrive via the M27 or A3(M), transitioning through the city’s busy arterial routes like the A2030 or M275. Given the density of residential areas in places like Copnor, Milton, and North End, we assess every site for access.
In many cases, modules are craned into position. While wide trunk roads simplify the initial transit, narrow terraced streets may require specific traffic management or specialized lifting equipment. We have experience delivering modular buildings in Portsmouth and will provide a detailed delivery quote based on your specific postcode and site layout. Please note that customers are responsible for ensuring a level, prepared base is ready before the delivery date.
Planning Permission and Building Regulations
Many garden rooms fall under 'Permitted Development' rules, but this depends entirely on the size, height, and position of the building, as well as the status of your property (e.g., if it is a listed building or in a conservation area). We recommend all Portsmouth residents consult with the Portsmouth City Council planning department or the relevant local authority for Fareham, Gosport, or Havant before proceeding. Building regulations may also apply if the structure exceeds a certain size or is intended for sleeping accommodation.
Lead Times and Ready to Order Units
We pride ourselves on efficiency. While traditional extensions can take months to build, our modular units are typically delivered within weeks of order confirmation. For those who need a solution even faster, we often have "Ready to Order" stock units available for immediate dispatch. The exact timeline for your project will be confirmed at the point of quotation.
