Precision-Engineered Modular Spaces
Unlike traditional timber garden buildings that require frequent maintenance, Adacon provides steel-framed modular structures designed for longevity. Our buildings are not converted shipping containers; they are purpose-built P600 modules manufactured in our controlled production facility. This process ensures high thermal efficiency and a level of internal finish—including plastered walls and laminate flooring—that matches a new-build home.
Typical Configurations and Sizes
The P600 system is inherently flexible, allowing Hull residents to design a space that fits their specific garden footprint. Each module provides approximately 13 m² of floor space, and these can be combined in various ways.
- Single Module (13 m²): Ideal for a private home office, a small treatment room, or a craft studio. These fit well into the standard suburban gardens found in areas like Kingswood.
- Double Module (26 m²): A popular choice for a spacious home gym or a secondary living area. The modules join side-by-side to create a wide, open-plan interior.
- Multi-Module L-Shapes (39 m²+): For homeowners with larger plots in rural East Yorkshire, four or more modules can be configured into L-shapes or two-storey blocks to create comprehensive garden annexes or hobby complexes.
You can explore these layouts and see how they look in 3D using our P600 configurator, which provides instant pricing as you add windows and doors.
Delivery and Access in Hull and East Yorkshire
We regularly supply modular buildings in Hull, with units typically arriving via the M62 and A63 corridor. The geography of Hull presents specific considerations for delivery. In denser residential areas like the Avenues or Victorian terraces near the city centre, narrow access or shared tenfoots can make traditional delivery difficult. In these instances, we often utilise hiab crane vehicles to lift modules over walls or existing structures.
For properties in the more open outskirts of Cottingham, Hessle, or Swanland, access is generally simpler, though we always conduct a site access review. It is the customer's responsibility to ensure a level, prepared base—such as a concrete slab or ground screws—is ready before the modules arrive.
Indicative Pricing for Hull Projects
The cost of a garden room depends on the number of modules, the choice of external cladding, and internal specifications like WCs or kitchenettes. For a garden-focused use, prices typically range between £15,000 and £35,000. This includes the building itself, the internal finishes, and the double-glazed uPVC windows and doors. Delivery is quoted as a separate item based on your specific location in the Hull area to ensure you only pay the actual transport cost.
What is Included as Standard?
Every Adacon garden room is delivered with a high-quality internal specification as standard. This means you do not need to hire decorators or flooring contractors after we leave. Standard features include:
- Steel frame construction with insulated walls, floor, and roof.
- Plastered and painted internal walls and ceiling.
- Laminate flooring and skirting boards.
- LED lighting and electrical sockets.
- Double-glazed external doors and windows.
- External cladding in a variety of colours.
Optional extras like air conditioning, internal partitions for a garden office, or full WC and shower compartments can be specified during the design phase.
Planning and Building Regulations
When installing a modular building in Hull, planning requirements depend on the size of the building, its height, and its position relative to your property boundaries. Many garden rooms fall under 'Permitted Development,' but rules can vary significantly between Hull City Council and East Riding of Yorkshire Council. We always advise checking with your local authority planning department before proceeding, especially if you live in a conservation area or a listed building.
Lead Times and Ordering
We pride ourselves on speed of delivery. While traditional extensions can take months of onsite mess, our P600 modules are built in a factory environment. Lead times are typically measured in weeks. Once your modules arrive in Hull, they are usually positioned and secured within a single day, drastically reducing the disruption to your home life.
