Simplicity 6 Aluminium Garden Room with Sliding Glass Doors in Anthracite Grey, by Forever Timber

Milwood Group supplied a Simplicity 6 Garden Room system for a picturesque residential setting, designed and installed by our Trade Partner, Forever Timber. The result is a refined, low-maintenance glass room that frames the garden beautifully while delivering year-round shelter and light.

Forever Timber are specialists in premium outdoor structures across the South East, combining handcrafted timber buildings with modern aluminium solutions. Their design-led approach, meticulous surveying, and tidy installation standards deliver beautiful, long-lived spaces tailored to each property and lifestyle requirement.

Why aluminium for a Garden Room?

Timber and aluminium both have their place. Timber offers warmth, natural texture and character, making it ideal where a traditional aesthetic is desired. Aluminium delivers slim sightlines, concealed drainage, and long-term durability with minimal upkeep, so paintwork, staining and seasonal movement are largely taken out of the equation.

For homeowners who want contemporary looks and everyday practicality, an aluminium garden room keeps its finish, resists warping, and integrates modern glazing and door systems with ease.

Project highlights

  • Elegant anthracite finish complements the brick and planting, keeping the focus on the garden views.
  • Sliding glass doors to the front and sides create flexible openings for ventilation and entertaining.
  • Slim posts and integrated guttering preserve clean lines and provide efficient rainwater management.

Installation requirements and approach

Forever Timber completed a detailed survey, then worked to our CAD approval to confirm dimensions, door clearances and glass sizes prior to manufacture. On site the wall plate was fixed to the host structure, posts were secured using bolt-to-ground brackets, and the integrated gutter with internal downpipe was connected for tidy drainage.

Sliding-door tracks were levelled carefully to ensure smooth running, and the single-glazed cheese frames were sealed to keep the weather out while maintaining the light feel of the room.

Why Garden Rooms are so popular in 2025

Homeowners want spaces that work hard all year: a quiet office with a view, a dining area that opens to the terrace in summer, or a sheltered lounge that extends the season. Aluminium garden rooms meet that demand with quick installation, minimal maintenance, excellent daylight, and compatibility with upgrades such as lighting, heating and shading for comfort in every month.

  • Refined aesthetics: slim profiles and colour-matched components deliver a premium finish

Timber or aluminium: choosing what is right

If a heritage look and natural materiality are the priorities, timber is a superb choice and Forever Timber excel in that craft. If low maintenance, slimmer frames and integrated modern glazing are key, aluminium is the smarter route. Many projects combine both: a brick or timber base with an aluminium roof and glazing above, as shown here.
