What is a Modular Garden Room?
A modular garden room is a pre-fabricated, self-contained structure designed for outdoor living or working space. Unlike traditional extensions, modular garden rooms are:

✔ Customisable in design, size, and features
✔ Fully insulated for year-round use
These structures are perfect for homeowners needing additional space without the disruption of a full-scale renovation.
Top 10 Benefits of a Modular Garden Room
1. Fast & Hassle-Free Installation
Unlike traditional extensions, which can take months, modular garden rooms are typically installed in 1–3 days. Since they are pre-manufactured, there’s minimal on-site disruption.
2. Cost-Effective Alternative to Extensions
Traditional extensions cost between £1,800 – £3,000 per m², whereas modular garden rooms start from £12,000 – £25,000, making them a budget-friendly option.
3. No Planning Permission Required
Most modular garden rooms fall under Permitted Development Rights, meaning you don’t need planning permission (subject to size and height restrictions).
