Custom Modular Garden Offices
We provide the P600 modular building system, a precision-engineered steel-frame solution manufactured in our specialist facility and delivered to Worthing ready for immediate use. These are not flat-pack kits or timber cabins; they are structural modules of approximately 13m² each that can be used individually or combined to create larger workspaces. For Worthing residents, this means a professional-grade office that avoids the maintenance issues associated with traditional wood structures.
Typical Office Configurations
The versatility of the P600 system allows for various layouts depending on your available garden space and work requirements. Homeowners typically choose from the following setups:
- Single Module (13m²): Ideal for a spacious solo office or a shared desk setup for two people. Fits comfortably in most suburban gardens in areas like West Tarring.
- Double Module (26m²): Created by joining two units side-by-side. This configuration suits small businesses, therapy rooms, or a combined office and home gym.
- L-Shape or Multi-Storey: For larger plots or complex requirements, modules can be arranged in L-shapes or even stacked to preserve garden footprint while doubling your floor area.

What is Included as Standard?
Every P600 module is delivered with a complete internal finish. When we quote for a project, the following features are included as standard:
- Fully insulated walls, floor, and roof for year-round thermal comfort.
- Plastered and painted internal walls (no exposed metal or plastic trunking).
- Laminate flooring and skirting.
- LED lighting and conveniently placed electrical sockets.
- Double-glazed uPVC windows and external doors.
- Exterior cladding in a range of colours, which can be configured wall-by-wall to suit your garden's aesthetic.
Optional extras include air conditioning for climate control, internal partitions for WCs or kitchenettes, and external decking to integrate the office into your landscaping.
Indicative Pricing for Worthing Projects
Pricing for a garden office depends on the number of modules, the complexity of the glazing, and optional internal fit-outs. For a typical home office use case, prices generally range between £15,000 and £32,000.

Delivery and Site Access in West Sussex
We regularly deliver modular buildings in Worthing and the surrounding West Sussex area. Logistics are typically managed via the A27 or A24 corridors. Our delivery team is experienced in navigating the specific geographic challenges of the region.
For properties in Worthing, site access is a primary consideration. While modern developments in areas like West Durrington often have wide access, older terraced streets near the town centre or seafront may have narrow road widths or parking restrictions. We deliver modules via HGV with a crane (HIAB) to lift the units into position. If your site has restricted access, overhead cables, or requires a crane lift over a house, we can advise on the feasibility during the quoting process. It is the customer's responsibility to ensure a level, prepared base is ready before the delivery date.
Lead Times
Our production process allows for lead times measured in weeks rather than months. Because the buildings are manufactured in a controlled factory environment, site disruption is kept to a minimum—usually limited to a single day for delivery and positioning. We occasionally have 'Ready to Order' stock units available for even faster deployment if your requirements match our standard stock specifications.
Planning Permission in Worthing
Many garden offices fall under 'permitted development' and do not require full planning permission, provided they meet specific criteria regarding height and placement. However, rules vary significantly depending on whether your property is in a conservation area, a listed building, or if there are specific local constraints. We always advise checking with Worthing Borough Council or Adur & Worthing Councils' planning department before commencing work. Similarly, building regulations may apply if the floor area exceeds a certain size or if the building includes sleeping accommodation.
