Professional Garden Rooms in Southampton
For homeowners in Southampton, increasing living space via a traditional extension can be a slow and invasive process. Adacon offers a faster, modern alternative with our P600 modular building system. These are not flat-pack kits or timber sheds; they are robust, steel-framed structures manufactured in a controlled environment and delivered to your property in a near-finished state. Whether you are located in the leafy suburbs of Bassett and Upper Shirley or have a more compact plot in Woolston or Bitterne, our modular approach adapts to your specific site requirements.
Configurations and Applications
The P300/P400/P600 modular range is based on a primary module of approximately 13 square metres. These units can be used individually or joined to create larger, complex floor plans. For those exploring garden rooms, the flexibility of the system allows for several common configurations:
- Single Module (13m²): Ideal for a private garden office or a compact creative studio.
- Double Module (26m²): Often used for home gyms or secondary lounge spaces, providing enough room for equipment and social seating.
- Multi-Module (40m²+): Four or more modules can be combined to create multi-room annexes, featuring separate living areas, kitchenettes, and shower rooms.
High-Quality Standard Specification
Every Adacon building is delivered with a comprehensive internal and external finish as standard. We do not believe in hidden extras for basic necessities. Your garden room includes:
- Structural Integrity: A precision-engineered steel frame with fully insulated walls, floor, and roof.
- Internal Finishes: Plastered and painted walls, durable laminate flooring, and integrated LED lighting.
- Glazing and Security: High-performance double-glazed uPVC windows and external doors.
- Custom Aesthetics: Exterior cladding available in a variety of colours, which can be selected wall-by-wall to match your garden’s landscape or your home’s existing architecture.
- Electrical: Pre-installed sockets and internal wiring ready for final connection.
Delivery and Installation in Southampton
Southampton presents a diverse range of access challenges, from the wide avenues of Highfield to the narrower, terraced streets found in areas like Portswood or Freemantle. Our delivery team is experienced in navigating the Hampshire road network, typically reaching the city via the M3 or M27. We deliver the modules via lorry-mounted cranes (HIAB) or, where access is restricted, we can coordinate with local Southampton crane hire specialists to lift modules over rooftops or obstacles.
It is the customer's responsibility to ensure a level, prepared base is ready before delivery. Because our modules are steel-framed, they require precise support. Once positioned, a local electrician will need to connect the building to your consumer unit, and a plumber will be required if you have opted for internal WCs or kitchenettes. You can get an immediate sense of how these units fit your space by using our configurator/p600 tool.
Indicative Pricing and Lead Times
For residential garden use, prices typically range between £15,000 and £35,000. This variance depends entirely on the number of modules, the amount of glazing requested, and the inclusion of optional extras like air conditioning or internal partitions. Compared to a brick-and-mortar extension in the Southampton property market, modular builds offer a significantly lower cost per square metre and a much faster return on investment. Lead times are usually confirmed at the point of quote, but we generally operate in weeks rather than the months required for traditional builds. For those in a hurry, we occasionally have 'Ready to Order' stock units available for even faster dispatch.
Planning and Local Regulations
Many garden rooms can be installed under Permitted Development rights, but this is never a guarantee. Rules vary based on the size of the building, its height, its distance from boundaries, and whether your property is in a conservation area (such as parts of the Southampton Old Town or specific suburban character zones). We strongly advise all customers to consult with the Southampton City Council planning department or the relevant Hampshire local authority before proceeding. Similarly, while our buildings are highly insulated, specific Building Regulations may apply if the building is intended for sleeping accommodation or exceeds certain floor areas.
