Garden Rooms for Havant Homeowners
Adacon supplies the P600 modular building system, a high-specification steel-framed solution for those seeking extra living space. Each module provides approximately 13 m² of floor area and is delivered to your site in Havant fully finished internally. This is not a flat-pack kit; the floor, walls, and roof arrive as a completed unit, ready to be lifted into position and connected to your services.
Our buildings are designed for year-round use. With high-performance insulation, double-glazed uPVC windows, and durable exterior cladding, they maintain comfortable temperatures in winter and summer. Many customers in the region choose these units for garden rooms that serve as quiet retreats, creative studios, or secondary lounges.
Configurations and Sizes
The versatility of the P600 system allows you to scale your building based on the size of your garden and your specific needs.
- Single Module (13 m²): Ideal for a compact home office or a treatment room. These fit comfortably into smaller Havant garden plots.
- Double Module (26 m²): A popular choice for garden gyms or larger guest rooms, providing a spacious rectangular or L-shaped layout.
- Four+ Modules (52 m²+): Suitable for large-scale multi-purpose buildings, including self-contained annexe spaces or expansive hobby rooms.
Because the modules can be combined side-by-side or end-to-end, you can create a layout that works with the unique dimensions of your property. You can explore these layouts using our free online configurator to see how windows and doors can be positioned to capture the best light in your garden.
What is Included as Standard?
Every P600 module is manufactured in our dedicated facility and arrives with a complete internal fit-out. We do not believe in hidden extras for basic necessities. Your garden room includes:
- Galvanised steel frame for longevity and structural integrity.
- Fully insulated walls, floor, and ceiling.
- Plastered and painted internal walls and ceilings.
- Quality laminate flooring.
- LED lighting and pre-installed electrical sockets.
- Double-glazed uPVC external doors and windows.
- External cladding in a choice of colours, which can be selected per-wall to suit your aesthetic.
Optional extras include WC and shower compartments, kitchenettes for self-contained use, and air conditioning units for climate control.
Indicative Pricing
For residential garden use, project prices typically range between £15,000 and £35,000. This range covers the cost of the modules and the internal fit-out. The final price depends on the total number of modules, the choice of internal partitions (such as adding a bathroom), and any specific cladding upgrades.
Please note that delivery to Havant, groundworks, and final utility connections are quoted separately. This ensures you only pay for the specific logistical requirements of your site.
Delivery to Havant and Surrounding Areas
We regularly supply modular buildings in Havant, Emsworth, and Hayling Island. Typically, modules are transported from our production facility via major routes like the A3(M) and A27. Access is a key consideration for any garden project in Havant.
In established residential areas, such as the terraced streets near Havant station or the narrower lanes in Old Bedhampton, we assess access for the delivery vehicle and the crane. For properties with restricted access where a standard lorry-mounted crane cannot reach, we can coordinate specialized lifting equipment. It is the customer's responsibility to provide a level, prepared base (such as a concrete slab or reinforced plinth system) before the building arrives.
Planning and Building Regulations
Many garden rooms can be installed under Permitted Development rights, but this depends on the size of the building, its height, and its position relative to your property boundaries. Havant Borough Council oversees planning for the area, and we always recommend checking their specific guidance or consulting a planning officer before proceeding. If your building is intended for sleeping accommodation, it will typically need to meet Building Regulations, which may require specific upgrades to the standard specification.
Lead Times and Ordering
We pride ourselves on efficiency. While a traditional brick-and-mortar extension can take months of on-site disruption, our modular buildings are manufactured off-site. Typical lead times from order to delivery are measured in weeks. Once the building arrives in Havant, the physical installation of the modules usually takes only a single day, significantly reducing the impact on your daily life and your neighbours.
