Professional Modular Garden Rooms
Adacon supplies the P600 modular building system, a steel-framed solution designed for longevity and thermal efficiency. These are not flat-pack kits or temporary structures; they are fully finished modules of approximately 13m² that arrive at your Colchester property ready for final connection. Our buildings are manufactured in our specialist facility and delivered to Essex via the UK's major trunk roads, typically arriving via the A12 or A120 before navigating local routes.
For those looking for high-quality modular buildings in Colchester, the P600 system offers a level of finish usually reserved for permanent residential construction. Every unit features high-density insulation in the walls, floor, and roof, ensuring the space remains comfortable throughout the Essex winter and cool during the summer months.
Configurations and Typical Layouts
The versatility of our system allows homeowners to design a space that fits their specific garden footprint. Because the modules can be joined side-by-side or end-to-end, you can create a wide variety of shapes.
Single Module (13m²)
Ideal for a generous garden office, a private treatment room, or a compact hobby space. This setup fits well in the smaller gardens found in newer developments like Braiswick or the residential streets around Highwoods.
Two-Module Layout (26m²)
By joining two units, you create a substantial space suitable for a home gym, a secondary lounge, or a guest annex. This configuration allows for internal partitioning to create separate storage or a WC compartment.
Large Scale & Multi-Storey
For larger plots in rural areas such as West Bergholt or Wivenhoe, we can combine four or more modules. Our system also supports two-storey builds, which is a significant advantage for those with limited ground space who need to maximise their square footage.
What is Included as Standard
We believe in transparent pricing and high specifications. Every garden room we deliver to Colchester includes:
- Galvanised steel frame for structural integrity.
- Full insulation package (walls, floor, and roof).
- Plastered and painted internal walls and ceilings.
- Laminate flooring and skirting boards.
- LED lighting and pre-wired double sockets.
- Double-glazed uPVC windows and a high-security external door.
- External cladding in a range of colours, selectable per wall.
Optional extras such as air conditioning units, internal staircases for double-storey layouts, and kitchenettes can be added through our free online configurator.
Indicative Pricing for Colchester Residents
The cost of a garden room depends on the number of modules, the complexity of the glazing, and optional interior fit-outs. Typically, our garden projects range from £15,000 to £35,000. This includes the building itself, finished internally and externally. Site-specific costs, such as delivery from our port of entry to your Colchester address and any required crane hire, are quoted separately to ensure accuracy. Groundworks and the final electrical connection to your home’s consumer unit remain the responsibility of the homeowner, though we can provide the necessary specifications for your local contractor.
Delivery and Installation in Essex
Colchester presents a variety of delivery scenarios. For properties with easy access from the A12, delivery is straightforward via a flatbed truck. However, we are experienced in navigating the more challenging access points of Colchester's historic centre and the narrow lanes of the surrounding villages. In instances where a truck cannot park directly adjacent to the base, we can arrange for a crane to lift the modules into position over walls or fences. It is essential that the customer provides a level, prepared base—such as a concrete slab or a heavy-duty plinth system—prior to our arrival.
Planning and Timelines
Many garden rooms fall under 'Permitted Development' rules, meaning they do not require full planning permission. However, local rules vary depending on the size of the building, its proximity to boundaries, and whether your property is in a Conservation Area (such as the Colchester Dutch Quarter) or an Area of Outstanding Natural Beauty. We always advise checking with Colchester City Council or a planning consultant before proceeding. Once ordered, lead times are typically measured in weeks. We also maintain 'Ready to Order' stock for those requiring an even faster turnaround.
