Professional Garden Workspaces in Hertfordshire
Adacon provides the P600 modular system, a versatile building solution designed for longevity and thermal efficiency. Unlike many garden room suppliers, we do not use timber framing or thin-walled panels. Our buildings are engineered with structural steel frames, ensuring they remain plumb and stable for decades. Each module provides approximately 13 m² of internal space, and these can be joined together to create larger, open-plan environments or multi-room layouts.
Typical Garden Office Configurations
Because the P600 system is modular, you can choose a footprint that fits your specific site in St Albans. Our garden offices typically fall into three categories:
- Single Module (13 m²): Ideal for solo professionals or freelancers. These fit comfortably into most suburban gardens in areas like Marshalswick or Fleetville.
- Double Module (26 m²): A spacious two-person office or a combined workspace and lounge area, often arranged side-by-side or in an L-shape.
- Multi-Module (39 m²+): Suited for small businesses with multiple employees, these larger builds can include partitioned WCs and kitchenettes.
High-Specification as Standard
Every building we deliver to St Albans arrives with a high level of internal finish. We believe a garden office should feel like a modern professional environment, not a shed. Standard features include:
- Insulated floors, walls, and roof for year-round thermal comfort.
- Plastered and painted internal walls (no plastic trim or raw ply).
- Durable laminate flooring and LED lighting.
- Double-glazed uPVC windows and external doors.
- Exterior cladding in a variety of colours, allowing you to match or contrast with your home.
You can further customise your build by adding air conditioning, internal partitions, or bespoke glazing layouts using our P600 configurator.
Indicative Pricing for St Albans Projects
While every project varies based on ground conditions and final specifications, most garden office projects in the St Albans area fall within the £15,000 to £32,000 range. This bracket typically covers the building manufacture and internal finishing. Factors that influence the final cost include the number of modules, the choice of premium cladding, and the inclusion of plumbing for WCs or kitchenettes.
Delivery and Access in St Albans
St Albans presents a variety of logistical considerations for modular delivery. Our modules are transported from our production facility via the M25 and M1, typically entering the city via the A414 or A1081. For properties in the historic city centre or narrow Victorian terraced streets near the Abbey, we carefully assess crane requirements to lift modules over existing structures. If you have a more rural site on the outskirts near Sandridge or Wheathampstead, we verify track widths for our delivery vehicles. All modular buildings in St Albans require a level, prepared base (such as concrete pads or a screw pile system), which remains the responsibility of the customer.
Planning and Regulations
Garden offices often fall under Permitted Development, but this is never guaranteed. Factors such as building height, proximity to boundaries, and your property's location within a conservation area—of which there are many in St Albans—will dictate whether a formal planning application is required. We always recommend contacting St Albans City and District Council or a qualified planning consultant to verify the requirements for your specific postcode before commencing work.

Our lead times are measured in weeks, not months, and because the majority of the build happens in our factory, on-site disruption at your home is kept to a minimum.
