A Superior Modular Alternative for Belfast Gardens
Adacon provides the P600 modular building system, a high-performance steel-framed solution designed to withstand the Irish climate while providing the internal comfort of a modern house. These are not flat-pack kits or basic timber summerhouses. Each module arrives at your Belfast property finished internally with plastered walls, LED lighting, and high-quality flooring. The primary benefit of our modular approach is the speed of installation; while traditional builds can take months of onsite disruption, an Adacon garden room is typically positioned and ready for final utility connection in a single day.
Typical Garden Room Configurations
Because the P300/P400/P600 modular range is modular, you can choose a footprint that suits your specific site, whether you have a narrow urban plot or a sprawling rural garden. Our garden rooms are frequently configured in the following ways:
- Single Module (approx. 13m²): Ideal for a private home office, a small treatment room, or a compact hobby space. This fits comfortably into most suburban gardens in areas like Stormont or Castlereagh.
- Double Module (approx. 26m²): Often arranged side-by-side or in an L-shape to create distinct zones, such as a garden gym with a separate shower room or a large open-plan studio.
- Four+ Modules: Suitable for multi-functional buildings, including guest accommodation or large-scale entertainment suites, providing the scale of a small bungalow.
For those specifically looking to move their professional life away from the kitchen table, our garden offices offer the acoustic privacy and thermal stability required for year-round work.
What is Included as Standard
Every P600 module is built to a consistent high specification to ensure longevity and comfort. Our standard package includes fully insulated walls, floors, and roofs, providing excellent thermal retention. Internally, we provide plastered and painted finishes, laminate flooring, and a full electrical fit-out including sockets and LED lighting. The exterior features double-glazed uPVC windows and doors, with a wide variety of cladding colours that you can select wall-by-wall to match your home’s aesthetic. We also offer optional extras such as internal partitions for WCs, kitchenettes, and air conditioning units for climate control.
Delivery and Installation in Belfast
Logistics for Belfast and Northern Ireland are managed through established transport routes, typically arriving via the Port of Belfast or Larne. From the docks, modules are transported by HGV to your location. We are experienced in navigating the specific challenges of Belfast’s geography. Whether your property is situated on a wide avenue in East Belfast or a more restricted site in the city centre, we assess access for the delivery vehicle and the crane required to lift the modules into position. For properties with narrow lanes or terraced access, a larger crane may be required to lift modules over the main house, a process we can advise on during the planning stage.
Indicative Pricing and Investment
For residential garden room applications, prices typically range between £15,000 and £35,000. This range depends heavily on the number of modules, the complexity of the internal fit-out (such as plumbing for bathrooms), and your choice of external finishes. To get a precise figure for your specific layout, we recommend using our configurator, which provides instant estimated pricing based on your design. Please note that groundworks, the preparation of a level base, and final connections to electricity and drainage are quoted separately and remain the responsibility of the customer.
Planning Permission in Northern Ireland
The requirements for planning permission and building regulations for garden rooms can vary significantly depending on the size of the building, its intended use, and your property’s specific location (for example, if you are in an Area of Outstanding Natural Beauty or a Conservation Area). We recommend that all Belfast customers consult with the Belfast City Council planning department or their relevant local authority before proceeding. While many small garden rooms fall under permitted development, this is project-specific and should always be verified formally.
Lead Times and Availability
We pride ourselves on lead times that are measured in weeks rather than months. By manufacturing in a controlled factory environment, we avoid the weather delays common to traditional construction in Northern Ireland. Once your order is confirmed and the production slot is allocated, we provide a clear delivery window. For those in a hurry, we occasionally have 'Ready to Order' stock units that can be dispatched even faster.
