This elegant garden office, designed by Miniature Manors, features striking black featheredge cladding. The bespoke 7m x 4m building serves as both a home office and gym, complete with an ensuite shower room. Thoughtfully crafted, it includes acoustic glazing and is prepped for a log burner installation-making it a versatile, year-round addition to any property.

A 7m x 4m garden office and gym

The 7m x 4m building provides ample space for dual functions: a productive home office and an invigorating exercise area. Miniature Manors specialise in creating multifunctional garden rooms, ensuring each design meets the client’s specific needs.

The inclusion of a fully fitted shower room adds convenience-perfect for freshening up after a workout or for avoiding interruptions during a busy workday. As part of their service, Miniature Manors handle all necessary groundwork to connect the shower room to the mains services.

Interior

Interiors with a new build aesthetic

The interior of this garden office exudes the look and feel of a modern new-build home. Plastered and decorated walls and ceilings are complemented by durable laminate flooring, creating a polished and functional finish.

Log burner

Prepping for a log burner

To meet the clients’ request for a log burner, Miniature Manors collaborated with a specialist installer, designing the structure to accommodate the stove’s specifications. The combination of full insulation and the log burner ensures this garden office remains warm and inviting during the colder months.

Glazing

Sliding doors with acoustic glazing

The sliding doors, fitted with acoustic glass, offer excellent sound insulation-reducing noise transfer to and from the garden room. The design features a 4-panel inline sliding door system, where two central panels slide back over fixed panels on either side.

This setup creates a generous opening, seamlessly connecting the indoor space with the garden. Inline sliding doors not only offer aesthetic appeal but also tend to be a cost-effective alternative to bi-fold doors.

Additional windows include a pair of desk-height openings on the left elevation and a small opening window in the shower room for ventilation.

Black featheredge cladding

The exterior is clad in black featheredge timber, offering a textured, characterful finish. Black cladding has become a popular choice for modern garden rooms, blending strikingly with natural garden hues while maintaining a timeless appeal.
