The P600 System for Cornwall Homeowners
Adacon provides a unique approach to expanding your home. Our P600 modular system is built around high-quality steel frames and factory-finished internals. Unlike traditional timber-framed summerhouses, our modules are engineered for longevity and thermal efficiency. We deliver these units across Truro and the surrounding districts, offering a turnkey solution for those who value speed, quality, and transparent pricing.
Typical Configurations and Uses
The P600 system is highly versatile, with each module providing approximately 13 m² of internal space. Because modules can be joined side-by-side or stacked, the possibilities range from compact studios to expansive garden annexes.
Single Module (approx. 13 m²)
Perfect for a dedicated garden office or a private treatment room. A single module fits comfortably into most suburban Truro gardens without dominating the landscape. It provides enough space for two desks, storage, and a seating area.
Double Module (approx. 26 m²)
By connecting two units, you create a substantial space ideal for a home gym, a large creative studio, or a guest suite. This layout often includes internal partitions to separate a main living area from a WC or storage room.
Large Multi-Module Builds (40 m²+)
For larger properties on the outskirts of the city, four or more modules can be combined to create multi-room facilities. These are frequently used as garden rooms that function as fully independent guest accommodation or large-scale hobby spaces.
What is Included as Standard?
We believe in transparency, which is why our standard specification is higher than many local timber alternatives. Every Adacon building delivered to Truro includes:
- Galvanised steel frame construction for maximum durability.
- Full insulation in walls, floor, and roof for year-round thermal performance.
- Plastered and painted internal walls and ceilings (no exposed plastic panels).
- Laminate flooring and skirting boards throughout.
- Double-glazed uPVC windows and external doors.
- Full electrical fit-out including LED lighting and multiple sockets.
- External cladding in a range of colours, which can be customised wall by wall to suit your garden's aesthetic.
Indicative Pricing in GBP
Pricing for a garden room depends on the number of modules, the complexity of the internal layout, and any optional extras like air conditioning or plumbing. For residential use in Truro, prices typically range from £15,000 to £35,000. This range covers everything from a basic single-module studio to a highly specified double-module build with premium finishes.

Delivery and Installation in the Truro Area
Getting a modular building to Cornwall requires careful logistics. Our units typically travel via the M5 and A30, entering Truro via the main trunk routes. However, we recognise that Truro presents unique access challenges. From the narrow historic streets near the Cathedral to the winding lanes of the surrounding villages, we assess every site individually.
If your property has restricted access—such as a terraced house with no side entrance or a site located on a steep Cornish hill—we may require a crane to lift the modules over existing structures. We work with local haulage and crane contractors familiar with modular buildings in Truro to ensure a safe delivery. The customer is responsible for providing a level, prepared base (usually a concrete pad or ground screws) and for the final connection to the local electrical grid and drainage.
Planning Permission and Regulations
Many garden rooms fall under 'Permitted Development' rules, meaning they do not require full planning permission. However, rules are project-specific and depend on the size of the building, its height, and its position relative to your property boundaries. Constraints may also differ if you live in a Conservation Area or a listed building within the city centre. We always advise checking with Cornwall Council before commencing work. Similarly, if you intend to use the building for overnight accommodation, Building Regulations will likely apply.
Why Choose Adacon?
We offer a professional, engineered alternative to the standard garden shed. Our buildings are manufactured in a controlled factory environment in Turkey, ensuring a level of finish that is difficult to achieve with on-site construction in the unpredictable Cornish weather. With lead times typically measured in weeks rather than months, you can have your new space ready to use far sooner than a traditional extension.
