Forest Chiltern 4.0m x 3.0m Log Cabin – Apex Roof, Double Glazed

The Forest Chiltern 4.0m x 3.0m Log Cabin is one of Forest Garden's most popular log cabins, combining a compact footprint with a surprisingly spacious interior. Its attractive reverse apex roof, fully glazed front elevation, and premium double glazing make it an ideal choice for anyone looking to create a stylish home office, hobby room, garden gym, or relaxing garden retreat. Offering approximately 10.2m² (110ft²) of internal floor space, the Chiltern provides a practical way to extend your living space without sacrificing too much of your garden.

Bright, Versatile and Designed for Everyday Use

The fully glazed front elevation allows plenty of natural light to enter the cabin, creating a bright and welcoming environment throughout the day. Meanwhile, the solid side and rear walls maximise internal wall space, making it easy to install shelving, desks, storage units, or gym equipment. The double entrance doors can be positioned on either the left or right-hand side during construction, allowing you to configure the cabin to suit your garden layout. With internal floor dimensions of approximately 3.73m x 2.73m, the Chiltern offers flexible accommodation suitable for:
  • Home offices.
  • Garden studios.
  • Hobby or craft rooms.
  • Home gyms.
  • Games rooms.
  • Additional garden living space.

High-Quality Construction

The cabin is manufactured from slow-grown Nordic Spruce, using 34mm smooth-planed interlocking log walls for excellent strength and natural insulation. Both the roof and floor are constructed from robust 19mm tongue and groove boards, providing a solid, long-lasting structure throughout. This model includes double glazed toughened glass as standard, helping improve insulation while increasing security and reducing external noise. The two large front windows feature practical tilt and turn opening mechanisms, allowing excellent ventilation while maintaining security.

Premium Roofing System

This version is supplied with a 24kg polyester felt roof complete with black sand felt underlay. The polyester-reinforced felt offers significantly greater tear resistance than traditional mineral felt and has an expected lifespan of up to 15 years when correctly installed. Alternative roofing options, including 34kg polyester felt and felt shingles, are also available within the Chiltern range. The cabin is supplied untreated and kiln dried, allowing you to apply your preferred finish after installation. A suitable solvent-based timber preservative should be applied immediately after assembly to protect the timber. Delivery is made using a crane off-load vehicle, with optional professional assembly available. The cabin should always be installed on a solid, level base, such as poured concrete.
