Professional Modular Garden Offices in Stevenage
As the demand for high-quality remote working spaces increases, residents in Stevenage are looking for alternatives to expensive loft conversions or disruptive home extensions. Adacon specializes in the P600 modular building system, a robust steel-framed solution designed for longevity and thermal efficiency. Unlike many providers, we do not sell converted containers; our modules are purpose-built for habitation, featuring plastered internal walls and high-performance insulation as standard.
Configurations to Suit Your Property
The P600 system is inherently flexible, allowing for various layouts depending on your available garden space and work requirements. Because the modules are approximately 13 m² each, they can be used individually or combined for larger teams or multi-functional uses. You can explore these layouts using our free P600 configurator to visualize how a building will sit on your site.
Single Module (approx. 13 m²)
Ideal for a single professional or a dedicated focus room. This fits comfortably in most suburban gardens in areas like St Nicholas or Pin Green. It provides ample space for a large desk, storage, and a seating area.
Double Module (approx. 26 m²)
By joining two modules side-by-side, we create a substantial workspace. This configuration is popular for small business owners who may employ one or two staff members, or for those who want to split the space between a garden office and a gym.
Multi-Module and Two-Storey Builds
For large estates or commercial applications, we can combine four or more modules. We also offer two-storey configurations, including internal or external staircases, which are excellent for maximizing footprint in tighter urban plots.
Standard Specifications
Every Adacon garden office is delivered with a high-end internal finish, removing the need for secondary contractors. Our standard specification includes:
- Galvanized steel frame construction
- Fully insulated walls, floor, and roof for year-round use
- Plastered and painted internal walls and ceilings
- Laminate flooring and LED lighting
- Double-glazed uPVC windows and external doors
- Configurable exterior cladding in various colours
- Multiple double sockets and a consumer unit
We also offer optional extras such as air conditioning, integrated kitchenettes, and internal WCs, making the unit entirely self-contained from the main house.
Indicative Pricing for Stevenage Projects
Price transparency is central to our process. For a standard garden office in the Stevenage area, indicative prices typically range from £15,000 to £32,000 including VAT. The final cost depends on the number of modules selected, the complexity of the glazing configuration, and any optional internal additions like plumbing or HVAC systems. Delivery is itemized separately based on your specific access requirements.
Delivery and Logistics in Stevenage
Stevenage is well-positioned for our logistics team, typically accessed via the A1(M) or the A602. We deliver modules fully finished from our production facility. Because the units are transported on a flatbed or Hiab vehicle, we must assess access to your specific property. Many Stevenage residential areas, particularly in the newer developments, have wide enough roads for crane offloading. However, for properties in older, narrower streets or terraced rows in the town centre, we may need to coordinate specialized crane lifts over the house or adjacent structures. The customer is responsible for providing a level, prepared base—such as a concrete slab or ground screws—and for the final electrical connection to the mains.
Local Planning Context
When installing modular buildings in Stevenage, you should consider local planning guidelines. Many garden offices fall under Permitted Development, provided they meet specific criteria regarding height, placement, and usage. However, rules can vary significantly if your property is in a conservation area or if the building exceeds certain dimensions. We always recommend checking with the Stevenage Borough Council planning department or a qualified planning consultant before finalizing your order.
Lead Times and Ordering
We pride ourselves on efficiency. While traditional construction projects can take months to complete, our lead times are typically measured in weeks. Once your specification is confirmed via a formal quote, we move to production and schedule your delivery slot. For those requiring an even faster turnaround, we occasionally have 'Ready to Order' stock units available for immediate dispatch.
Why Choose Adacon?
We provide a permanent building feel with a modular timeline. By building in a controlled factory environment, we eliminate the weather delays and mess associated with on-site builds. Our P600 system is a professional investment designed to add value to your property and provide a high-performance workspace that remains comfortable in both the height of summer and the middle of winter.
