Timeless Garden Rooms  5m × 3m contemporary garden office

Timeless Garden Rooms designs and builds each of its garden rooms to order, offering bespoke layouts and specifications tailored to meet each customer’s needs. A recent project highlighted this customisation, where the acoustic performance of the building was optimised to suit the client’s requirements.

Two Distinctive Styles:

Timeless Garden Rooms offers two architectural styles:

  • Classic Designs – Featuring pitched roofs and traditional detailing.
  • Contemporary Flat-Roofed Designs – Showcasing sleek Larch cladding paired with dark grey door and window frames for a modern aesthetic.

Below, we explore three completed projects, each demonstrating how Timeless Garden Rooms can tailor size, layout, and finishes to individual preferences.

At a glance

  • The range: Flat-roofed designs in larch cladding with dark grey door and window frames, alongside a classic range with pitched roofs and traditional detailing.
  • 5m × 3m office: A door on the front and two casement windows on the side at desk height, for fresh air and daylight where the desk sits.
  • 3m × 3m office: Outward-opening French doors on the front and a single casement window on the side.
  • 5m × 3m hobby room: Plastered and decorated walls and a wooden floor inside, with bi-fold doors opening onto the garden and a picture window on the side.
  • Company: Timeless Garden Rooms, whose flat-roofed buildings stay under 2.5m high so they can go within 2m of a boundary.

Garden office

5m x 3m garden office

This spacious 5m x 3m garden office features a single-glazed door on the front elevation and two casement windows on the side. The casement windows, positioned at desk height, allow for fresh air circulation and optimal natural light.

The building’s flat-roof design maintains a maximum height of 2.5m, making it ideal for installation within 2m of a property boundary while adhering to UK planning rules.

Compact office

3m x 3m garden office

This compact 3m x 3m home office is another example from the contemporary range. It features outward-opening French doors on the front elevation, perfect for warm days. A single casement window on the side provides additional ventilation and light.

Hobby room

5m x 3m hobby room

This 5m x 3m building has been designed as a hobby room, highlighting the high-quality finishes typical of the contemporary range. Inside, plastered and decorated walls paired with a wooden floor create a space comparable to a new-build home interior.

The exterior is just as impressive. The Larch cladding and dark grey frames create a striking look, while bi-fold doors on the front elevation open the room onto the garden. A picture window on the side elevation adds an extra touch of style and practicality.

Materials

Durable and low-maintenance exterior

Larch cladding is a standout feature of the contemporary range. Naturally resistant to rot and fungal attack, it requires minimal maintenance. Initially honey-toned, it weathers gracefully to a silvery-grey patina over time, without compromising durability. For those who prefer to preserve the original colour, UV oil can be applied periodically.

Year-round use

Transparent pricing and year-round comfort

Timeless Garden Rooms prides itself on offering transparent pricing, providing an upfront quote that includes all elements of the project. This ensures there are no unexpected costs, unlike some other garden room providers.

Each garden room is built for comfort and usability year-round, with high-quality insulation, a tailored electrical package, and professional interior and exterior finishes.
