Permission free Garden Room

Permission free Garden Room

At Pecasa, based in Colonial Way, we specialise in crafting beautifully designed permission free garden rooms that offer practical, stylish, and flexible space solutions — all without the hassle of planning permission. Whether you need a home office, a hobby room, an annexe for guests, or a peaceful garden studio, our garden rooms are designed to be compliant with permitted development regulations, saving you both time and stress.

Build Without the Bureaucracy

Thanks to UK permitted development rights, most homeowners can now build a garden room without applying for planning permission — as long as the structure meets certain criteria. At Pecasa, we ensure every garden building is designed and constructed within these limits, giving you complete peace of mind.

What Makes a Garden Room “Permission Free”?

In most cases, your garden room can be built without planning permission if it:

  • Does not exceed 2.5 metres in height (if within 2m of a boundary)

  • Takes up less than 50% of the total area of land around your house

  • Is not used as a separate living accommodation (though annexe room builds can be explored with appropriate checks)

  • Is not built on designated land or listed buildings

Our team at Pecasa will guide you through the regulations, so you don’t have to worry. We handle everything from design to build, ensuring compliance every step of the way.

Annexe Room Build – For Guests or Independent Living

If you’re looking for something more self-contained, such as a garden annexe room, we offer bespoke solutions for extended families or guests. While annexe rooms sometimes require approval, our team can design within permitted limits where possible, or assist with applications if needed. These builds are perfect for:

  • Elderly parents

  • Grown-up children

  • Visiting guests

  • Rental opportunities

Garden Studio and Office Solutions

In today’s remote work era, a garden studio or garden office is more than a luxury — it’s a necessity. At Pecasa, we provide insulated, all-season garden studios that enhance productivity and privacy without compromising on design. Whether you’re a freelancer, artist, therapist, or small business owner, our studios and offices provide an ideal setting right at home.

Transparent Pricing – No Hidden Costs

We believe in honest and clear pricing. The cost of a garden room depends on its size, features, and customisation. On average:

  • Garden room costs start from £12,000 to £25,000

  • Annexe room builds range from £25,000 to £50,000, depending on amenities

  • Garden studios typically cost around £15,000 to £30,000

What Size Garden Room Can I Build?

Permitted development rights allow for generous space options. Generally, you can build up to 30 square metres without planning permission if certain conditions are met. Common sizes include:

  • Small (3m x 2.5m) – Ideal for compact offices

  • Medium (4m x 3m) – Great for studios or gyms

  • Large (5m x 4m or more) – Suitable for annexe rooms or multi-purpose use

Our designers will help you choose the right dimensions while staying within the legal limits.

London Outhouse Costs

If you’re based in London, you might wonder about the cost of building an outhouse or garden room. Due to urban property considerations and premium materials, London outhouse costs can vary between £15,000 to £35,000. At Pecasa, we provide cost-effective yet premium-quality builds that are both durable and elegant, designed for city living.
