A Swift Unlimited garden room: a future-proofed investment

A 10.87m × 4m garden building with an office, a gym, a shower room and a kitchenette, approved at 2.85m high and laid out to become living accommodation later.

Multi-room garden room by Swift
Swift Unlimited  10.87m × 4m, multi-room

The team at Swift Unlimited are experienced names in the garden room industry. They offer well-specified designs with a long lifespan, creating buildings that can evolve with their customers’ changing lifestyles and needs.

This multi-room garden room is an excellent example of this philosophy. Designed to serve as a home office, gym, and family relaxation space today, it’s also configured to evolve into living accommodation for a family member in the future.

At a glance

  • Size: 10.87m × 4m, with planning permission for a height of 2.85m.
  • Layout: An office with wrap-around glazing at one end, a slightly larger gym with 3m-wide sliding doors at the other, and a shower room and L-shaped kitchenette between them.
  • Future use: Planned so it could become living accommodation for a family member, which would need a further planning application and Building Regulations.
  • Exterior: Western Red Cedar, powder-coated aluminium doors, windows and trims, and a composite front step.
  • Company: Swift Unlimited, who secured planning permission for the extra height.

Layout

Versatile internal layout

The garden room’s internal space is arranged into four distinct uses:

  • Home Office: Featuring wrap-around glazing that frames stunning views of the garden, this workspace provides an inspiring setting. Who needs a city corner office when you can have this?
  • Home Gym: Positioned at the opposite end of the building, this slightly larger room features a 3m-wide set of sliding doors overlooking the garden. Additional rear wall windows can be opened for ventilation during workouts.
  • Shower Room & Kitchenette: Between the two main rooms is a spacious shower room. This leaves an L-shaped room equipped with a kitchenette, ideal for convenience today and preparation for future uses.

The addition of the shower room and kitchenette is not only practical but also an excellent way to future-proof the building.

Planning

Taller garden rooms with planning permission

Under Permitted Development rules, garden rooms built within 2m of a boundary are limited to a height of 2.5m. However, this height may not be sufficient for some uses, such as a home gym.

Swift Unlimited offers bespoke designs and can help clients secure planning permission for taller structures. In this case, they successfully obtained approval for a 2.85m-high building, offering enhanced functionality and comfort.

Future use

Planning for living accommodation

Should the owners wish to convert the space into living accommodation for a family member in the future, they would need to submit a further planning application and ensure compliance with building regulations.

Size

Bespoke dimensions

Unlike many garden room companies that offer standardised sizes, Swift Unlimited tailors their designs to exact specifications. This particular garden room measures an impressive 10.87m wide by 4m deep, designed to fit the client’s precise needs.

Materials

High-quality, low-maintenance materials

When future-proofing a garden room, ease of maintenance is a key consideration. Swift Unlimited uses a range of premium, low-maintenance materials that ensure the building remains attractive and durable for years to come.

  • Western Red Cedar Cladding: Naturally beautiful and long-lasting.
  • Powder-Coated Aluminium Doors & Windows: Robust and resistant to wear.
  • Composite Decking: The front step features a composite board that resists fading, rotting, and slipperiness.
