Professional Modular Garden Offices in Portsmouth
As remote work becomes a permanent fixture for many professionals in the Solent region, the demand for dedicated, quiet workspaces has grown. Adacon supplies the P600 modular building system, a high-specification steel-framed solution that outperforms traditional timber garden rooms in durability and thermal performance. These are not converted containers; they are purpose-built modules manufactured in our controlled facility and delivered to your property in a near-complete state.
Our garden offices are popular for those seeking a distinct separation between home and work life. Because the modules are fully finished internally with plastered walls, laminate flooring, and integrated electrics, the onsite disruption to your home is kept to an absolute minimum. You can explore our full range of garden offices to see how the P600 system adapts to different professional needs.
Configurations for Portsmouth Properties
Portsmouth presents unique geographic and architectural challenges, from the dense residential streets of Portsea Island to the more open suburbs of Cosham and Wymering. Our modular system is designed to scale based on your available space:
- Single Module (13 m²): Ideal for a solo professional or a two-person desk setup. Fits comfortably into most urban garden plots common in Southsea.
- Double Module (26 m²): A spacious executive suite or a shared studio space for a small local business team.
- Multi-Module L-Shapes: For larger properties, these configurations can incorporate a dedicated office space alongside a gym or guest room, providing a multi-functional garden retreat.
Each module can be customised via our P600 configurator, allowing you to choose the exact placement of double-glazed uPVC windows and external doors to maximise natural light and garden views.
What is Included as Standard
We believe a garden office should be ready for immediate use. Every Adacon P600 module includes:
- Full structural steel frame for long-term stability.
- Highly insulated walls, floor, and roof for year-round comfort.
- Plastered and painted internal walls (not plastic cladding).
- Laminate flooring and LED lighting.
- Internal sockets and a consumer unit.
- Double-glazed uPVC windows and secure external doors.
- Exterior cladding in a variety of selectable colours.
Optional extras include integrated WC and shower compartments, kitchenettes for self-contained working, and air conditioning units for temperature control during the summer months.
Indicative Pricing
The cost of a garden office in Portsmouth typically ranges from £15,000 to £32,000. This price band covers most single and double-module configurations with standard internal finishes. Final costs vary depending on the specific number of modules, window and door configurations, and any optional internal additions like plumbing or premium cladding. Please note that groundworks, final utility connections, and delivery are quoted separately to ensure accuracy for your specific site.
Delivery to Portsmouth and Hampshire
Portsmouth’s unique geography—connected primarily by the M27, A3(M), and A27—requires careful logistics planning. Our modules are delivered via heavy goods vehicles and typically positioned using a Hiab crane or a separate mobile crane. For properties in terraced areas or streets with narrow access, we conduct thorough assessments to ensure the modules can be safely landed.
We regularly supply modular buildings in Portsmouth and are familiar with the local transit routes across the city. Whether your site is a rural location on the outskirts or a compact city-centre garden, we itemise delivery costs clearly in your quotation. Customers are responsible for ensuring a level, prepared base (such as a concrete slab or reinforced plinth system) is ready before the delivery date.
Planning Permission and Building Control
Many garden offices fall under 'Permitted Development' rules, but this is never a guarantee. In Portsmouth, factors such as the size of your garden, the height of the building, and whether you live in a conservation area (such as parts of Old Portsmouth or Southsea) will influence whether you need formal planning permission. We always advise checking with Portsmouth City Council or your specific local authority before proceeding. Similarly, if the building exceeds certain size thresholds or includes specific plumbing, Building Regulations may apply.
