Professional Workspaces for West Sussex Homeowners
As remote and hybrid work become the standard for professionals in Horsham, the need for a dedicated, thermally efficient workspace has grown. Adacon supplies the P600 modular building system, a robust steel-framed solution designed to provide a quiet, comfortable environment all year round. These are not simple sheds; they are high-specification garden offices that arrive with plastered walls, integrated electrics, and high-performance insulation.
Configurations for Every Property
The P600 system is based on individual 13 m² modules. Because these units can be connected side-by-side or stacked, we can accommodate a wide range of Horsham site types:
- Single Module (13 m²): Ideal for typical residential gardens in areas like Needles or Holbrook. This provides a spacious desk area, storage, and seating.
- Double Module (26 m²): A larger workspace suited to businesses that require client meeting space or room for two full-time desks.
- Multi-Module and Two-Storey: For larger rural plots on the outskirts of Horsham, we can create substantial complexes, including internal staircases and separate rooms for gyms or studios.
You can experiment with these layouts and add your own window and door placements using our online configurator to get an instant estimate.
What is Included as Standard
Every Adacon building is manufactured in our dedicated facility and delivered to your site with the following specifications:
- Fully insulated floor, walls, and roof for UK winter conditions.
- Plastered and painted internal walls (no plastic trunking or exposed panels).
- Laminate flooring and LED lighting packages.
- Double-glazed uPVC windows and secure external doors.
- External cladding in a range of colours, which can be selected wall-by-wall to suit your garden’s aesthetic.
Optional extras include WCs, shower rooms, kitchenettes for self-contained working, and air conditioning units for climate control.
Indicative Pricing for Horsham Projects
The cost of a garden office in Horsham typically ranges from £15,000 to £32,000. The lower end of this scale covers a high-spec single module, while the upper end includes multi-module builds or units with extensive glazing and internal plumbing. These prices are indicative and depend on the final specification and module count. Delivery is quoted separately based on the specific requirements of your Horsham address.
Delivery and Installation in Horsham
Horsham presents a variety of delivery scenarios. Our modules are transported via the M23 and A24 corridors, typically reaching Horsham via the Broadbridge Heath or Hop Oast interchanges. For properties in the town centre with narrower residential streets or terraced housing, we coordinate crane lifts to position the modules safely over fences or walls. For rural sites towards Southwater or Warnham, we assess track access to ensure our delivery vehicles can reach the prepared base. The customer is responsible for ensuring a level base (usually concrete pads or a slab) and the final connection of services, though we provide the full technical spec for your local tradespeople to follow.
Planning Permission in West Sussex
Many garden offices fall under Permitted Development, but this is never guaranteed. Factors such as building height, proximity to boundaries, and whether your home is in a Conservation Area—such as the Horsham Town Centre or Causeway areas—will influence the requirements. We always advise customers to consult with Horsham District Council or a planning consultant before proceeding. Similarly, while our buildings are highly insulated, specific Building Regulations may apply depending on the size and use of the building.
