Precision-Engineered Garden Rooms for Grantham Homes
Adacon provides a modern solution for Grantham residents needing extra space. Our P600 system consists of steel-framed modules, each approximately 13m², manufactured in our dedicated facility. These are not flat-pack kits; they are delivered as structural units, fully finished internally with plastered walls, LED lighting, and flooring already installed. Because we manufacture in a controlled environment, we avoid the weather-related delays common with local Grantham building projects.
Typical Configurations and Layouts
The P600 system is highly flexible, allowing Grantham homeowners to choose a scale that suits their specific plot. You can explore these layouts in real-time using our P600 configurator to visualize your build.
- Single Module (13m²): Ideal for a private garden office, a small treatment room, or a compact hobby space.
- Double Module (26m²): A popular choice for a spacious home gym or a multi-functional garden lounge with room for a kitchenette.
- Four+ Modules (52m²+): These larger footprints are often used for multi-generational living spaces or significant home business premises.
For those looking specifically for professional workspaces, our garden offices provide the acoustic and thermal performance required for a full-time career from home.
What is Included as Standard?
We believe in transparent specifications. Every P600 module delivered to Grantham includes:
- Fully insulated floor, walls, and roof for year-round comfort.
- Plastered and painted internal finishes (no visible joints or plastic panels).
- Laminate flooring and integrated LED lighting.
- Double-glazed uPVC windows and external doors.
- Choice of external cladding colours, selectable for each wall.
- Internal electrical sockets and a consumer unit ready for final connection.
Indicative Pricing for Grantham Projects
For residential garden use, project costs typically range between £15,000 and £35,000. The final price depends on the number of modules selected and any optional extras such as air conditioning, internal WCs, or specialized cladding. Delivery is quoted as a separate itemized cost based on your specific Grantham postcode and site access requirements.
Delivery to Grantham and South Kesteven
Grantham’s location near the A1 and A52 makes it highly accessible for our logistics teams. Modules typically arrive via the A1 corridor, entering the town through main arterial routes. However, we recognize that Grantham has a diverse range of property types. If you live in a Victorian terrace near the town centre or a property with restricted access in a surrounding village, we can assess whether a standard HIAB crane delivery is possible or if a larger mobile crane is required. Customers are responsible for ensuring a level, prepared base is ready before delivery, and for the final connection of electricity and drainage. We provide all necessary technical drawings to assist your local contractors in this preparation.
Planning and Local Authority Guidance
When installing modular buildings in Grantham, homeowners should consider local planning guidelines. While many garden rooms fall under Permitted Development, this is never guaranteed. Factors such as the building’s height, its proximity to your boundary, and whether your home is in a conservation area or a listed building status will affect requirements. We always recommend contacting South Kesteven District Council to confirm if planning permission or building regulations approval is necessary for your specific project.
