Professional Modular Buildings for Chelmsford Gardens
Unlike traditional timber structures or converted shipping containers, Adacon garden rooms are purpose-built steel-framed modules. Each P600 module provides approximately 13 square metres of internal space, designed to withstand year-round use in the UK climate. Our buildings are manufactured in a controlled environment to ensure consistent quality, then transported to Essex for final placement.
Typical Configurations and Sizes
The versatility of the P300/P400/P600 modular range allows homeowners to scale their project based on available garden space and intended use. Because modules can be joined side-by-side or in L-shapes, your garden room can grow beyond a simple single-room layout.
- Single Module (13m²): Ideal for a spacious garden office or a compact home salon. This fits comfortably into standard suburban plots in areas like Chelmer Village.
- Double Module (26m²): Suited for home gyms or larger multi-purpose studios. This configuration allows for internal partitions to create separate storage or cloakroom areas.
- Four+ Modules (52m²+): Larger configurations are frequently used for multi-generational living spaces or significant home business hubs on larger rural plots surrounding Chelmsford.
What is Included as Standard?
We deliver our buildings fully finished internally, removing the need for weeks of on-site trades. Every P600 module includes:
- Fully insulated floors, walls, and roof for thermal efficiency.
- Plastered and painted internal walls and ceilings.
- Laminate flooring and integrated skirting.
- Double-glazed uPVC windows and external doors.
- LED lighting and a suite of electrical sockets.
- External cladding in a range of colours, selectable via our configurator/p600 tool.
Indicative Pricing for Chelmsford Projects
Pricing for a garden room in Chelmsford typically ranges from £15,000 to £35,000. The final cost depends on the number of modules, specific window placements, and optional extras such as air conditioning, kitchenettes, or WC compartments. This price excludes transport, which is quoted separately based on distance and site access. For an immediate estimate tailored to your design, you can use our online tool to request a quote.
Delivery and Installation in the Chelmsford Area
Chelmsford’s geography presents varied access requirements. We regularly deliver via major trunk roads including the A12 and A130. For properties in more congested areas or terraced streets closer to the city centre, we assess crane requirements to lift modules over existing structures into rear gardens. In more rural parts of the Chelmsford district, such as the Rodings or the Hanningfields, we ensure that local lanes are suitable for the transport vehicles. A level, prepared base must be in place before delivery; we can provide specifications for your groundworks contractor to ensure a seamless installation.
Local Authority Considerations
When installing garden rooms, many projects fall under Permitted Development rights. however, rules regarding height, placement, and total land coverage can vary depending on whether your home is in a conservation area or is a listed building. We recommend that all Chelmsford customers consult with Chelmsford City Council’s planning department or a qualified planning consultant to confirm the requirements for their specific site before proceeding with an order.
Lead Times and Availability
Our lead times are measured in weeks rather than months, significantly faster than traditional brick-and-mortar or bespoke timber builds. Once your configuration is finalised, we provide a confirmed delivery window. We also maintain a range of 'Ready to Order' stock units for those requiring a faster solution for modular offices or basic garden studios.
