    Garden Offices FAQs

    Our garden offices are designed with permitted development in mind, so you usually won’t need planning permission. That’s the case for most houses, even in protected areas like conservation areas or areas of outstanding natural beauty.

    But, if you live in a flat or a listed building, the rules are different – you’ll always need planning permission.

    Our garden offices are designed to suit a variety of budgets and needs. Our starting prices, inclusive of VAT, are as follows:

    • The Snug: Micro Garden Office, 3.3 x 2.2m, £17,146 inc. VAT
    • The Studio: Mini Garden Office,  4.4m x 3.3m, £19,890 inc. VAT
    • The Lodge: Small Garden Office, 5.5m x 3.3m,  £24,480 inc. VAT
    • The Lodge Plus: Medium Garden Office, 6.6m x 3.3m, £26,350 inc. VAT
    • The Retreat: Large Garden Office, 5.5m x 4.4m, £27,200.00 inc. VAT
    • The Retreat Plus: Extra Large Garden Office, 6.6m x 4.4m, £27,880.00 inc. VAT
    • The Estate: XXL Garden Office, 7.7m x 3.3m, £27,818 inc. VAT

    These prices provide a starting point. Your final cost will depend on your chosen finishes, fixtures, and any additional features or customisation. Contact our team for an estimated quotation today.

    Unlike traditional wooden garden offices that require regular upkeep, our structures are built to last. With durable steel facing, your garden office is naturally waterproof, pest-proof, and rot-proof, eliminating the need for constant maintenance and painting. The robust steel frame ensures structural integrity, while double-glazed windows offer insulation and security.

    This focus on quality materials and construction means your garden office will stand the test of time, providing a comfortable and functional workspace for years to come. Our confidence in our product is reflected in our 10-year structural warranty and 1-year warranty on fixtures and fittings, giving you peace of mind and the freedom to focus on what matters most – your work.

    The maximum height allowed for your garden office depends on its location within your property and local planning regulations.

    If your garden office will be situated more than 2 metres from any boundary, you typically have more flexibility with the height, often reaching up to 2.5 metres for a flat roof or 3 metres for a pitched roof. However, if your garden office is within 2 metres of a boundary, the maximum permitted height is usually 2.5 metres, regardless of the roof style.

    It’s important to consult your local council’s planning department to confirm the specific regulations that apply to your property and garden office project. They can provide detailed guidance on permitted heights, design restrictions, and any necessary planning permissions.

    Our garden offices are designed with these regulations in mind, offering a range of options that follow standard permitted development guidelines.

    Garden office installations can vary widely depending on the size, complexity, and materials used. Some companies may take multiple days, but at RJ Insulation, we understand the value of your time.

    Our garden offices are built to order with the highest quality materials, ensuring a premium product that’s delivered to your doorstep in 4-6 weeks. Once your foundation is in place, our expert team can install your garden office in just one day.
