Custom Modular Garden Rooms for London Properties
Adacon supplies the P300/P400/P600 modular range, a precision-engineered modular building solution manufactured in our dedicated facility. Each module provides approximately 13 m² of floor space, framed in structural steel for long-term durability. These are not flat-pack kits; they are delivered to your London address with internal finishes already complete. Our system is designed to be versatile, allowing you to link modules side-by-side or in L-shaped configurations to fit the specific dimensions of your garden.
London Living: Who Our Garden Rooms Suit
Our typical London customers are homeowners looking to maximise their outdoor space without the disruption of a traditional brick-and-mortar extension. The P300/P400/P600 modular range is ideal for:
- Home Professionals: Create a dedicated environment by browsing our garden offices, designed to separate work life from home life.
- Fitness Enthusiasts: The steel-framed floor provides the necessary rigidity for home gyms and heavy equipment.
- Creative Studios: High-spec insulation and double glazing make these units suitable for art studios or music rooms that require consistent temperatures.
- Extended Living: Using the P600 as a hobby room, cinema room, or a quiet retreat away from the main house.
Configurations and Space Planning
Space is at a premium in Greater London, which is why the P300/P400/P600 modular range's modularity is a significant advantage. You can explore these layouts on our P600 configurator to see how they fit your plot.
Single Module (13 m²)
Perfect for narrow London gardens or Victorian terrace plots. A single unit provides ample space for a two-person office or a compact garden gym.
Double Module (26 m²)
Two modules joined side-by-side create a substantial room suitable for a large family playroom or a professional salon. This configuration allows for internal partitions if you need to separate a storage area from the main living space.
Four+ Modules (52 m²+)
For larger properties in areas like Richmond or Bromley, multiple modules can be combined to create multi-room annexes or large-scale hobby blocks.
What is Included as Standard
Every P600 module is delivered with a high-specification internal finish. We do not supply shells; we supply ready-to-use spaces. Standard features include:
- Fully insulated walls, floor, and roof for year-round use.
- Plastered and painted internal walls and ceilings.
- Hard-wearing laminate flooring.
- LED lighting and pre-installed electrical sockets.
- Double-glazed uPVC windows and external doors.
- Exterior cladding in a variety of colours, which can be selected wall-by-wall to suit your garden's aesthetic.
Optional extras such as WC and shower compartments, kitchenettes, air conditioning, and external decking are available to further customise the build.
Indicative Prices for London Projects
While every project varies based on the final specification and site requirements, garden rooms typically fall within the £15,000 to £35,000 price range. A single-module garden office usually starts at the lower end of this bracket, while multi-module builds with added plumbing or high-end cladding sit at the upper end. For a specific breakdown tailored to your design, you can generate an estimate via our online tools or request a formal quote.
London Delivery and Site Access
We deliver to all London boroughs and the wider South East. Most units arrive via the M25 and major arterial routes like the A4, A40, and A12. London present unique logistical challenges, including narrow residential streets and Red Routes. We handle the transport to your kerbside as part of the quoted price. However, the final placement often requires a crane lift, particularly for terraced houses without side access. We advise customers to consider these factors early in the planning stage.
Lead Times
Our production process in Turkey allows for consistent quality and predictable timelines. Typical lead times from order to delivery are measured in weeks rather than months. We also maintain a selection of "Ready to Order" stock units for customers who require a faster turnaround for their garden project.
