Composite Garden Rooms and Sheds

A composite garden room can provide valuable additional space without changing the main structure of your home.

Our range of Ronjack composite garden buildings includes options suitable for working, relaxing, hobbies and outdoor storage. Their contemporary appearance complements both modern and traditional gardens, while the composite construction reduces the ongoing maintenance associated with conventional timber buildings.

Available models and specifications vary, allowing you to select a garden room or shed suited to your available space and intended use.

What Can a Composite Garden Room Be Used For?

A garden building can serve many different purposes beyond conventional tool storage.

Depending on the selected model, size and specification, composite garden rooms can be used as:

  • Garden home offices
  • Hobby and craft rooms
  • Outdoor lounges
  • Relaxation spaces
  • Garden storage rooms
  • Tool and equipment sheds
  • Bicycle storage
  • Seasonal furniture storage
  • Farm and agricultural storage
  • Firewood storage
  • Small workshops
  • General-purpose garden buildings

Before ordering, consider the space, ventilation, power, insulation and security required for the intended use. Not every model will be suitable for every application.

Composite Garden Offices

Working from home can be difficult when living and working activities share the same rooms. A dedicated garden office can create a clearer separation between home life and the working day.

Selected composite garden rooms can provide space for desks, equipment and office storage. Their modern appearance allows them to sit comfortably within landscaped gardens without looking like traditional utility sheds.

If a building will be used regularly as an office, consider:

  • Internal dimensions
  • Natural light
  • Ventilation
  • Insulation
  • Heating
  • Electricity and internet access
  • Door and window positioning
  • Security
  • The location of the building within the garden

Any electrical or specialist work should be completed by an appropriately qualified professional.

Composite Garden Sheds for Storage

Smaller composite garden buildings provide a durable option for storing tools, gardening equipment, bicycles and seasonal outdoor furniture.

They can also be useful on farms and rural properties for suitable equipment, crop or firewood storage. Always check the dimensions, ventilation and load requirements of the selected building before deciding what will be stored inside.

Unlike untreated timber, composite wall boards require no routine painting or staining, helping reduce the ongoing work involved in maintaining the exterior.

What Is the Seymour Collection Made From?

The wall boards used in the Ronjack Seymour Collection are manufactured from:

  • 60% recycled wood, milled for consistency
  • 35% high-density polyethylene
  • 5% additives

This combination creates a wood-plastic composite material that brings together recycled wood content and the durability of high-density polyethylene.

The additives and manufacturing treatments are designed to improve the material’s performance when exposed to UV light, fungi and changing outdoor conditions.

What Makes Composite Garden Buildings Different?

Traditional timber garden buildings can require regular painting, staining or preservative treatment to protect their exterior surfaces.

The composite wall boards used in the Seymour Collection are:

  • Moulded into the required profiles
  • Coloured during manufacture
  • Treated with antifungal agents
  • Finished with additives that reduce the effects of UV exposure
  • Designed for changing British weather
  • Pre-cut to support straightforward assembly
  • Low-maintenance
  • Resistant to moisture-related deterioration

High-density polyethylene contributes strength and stiffness to the composite material, helping create durable components for outdoor garden buildings.

Are Composite Garden Rooms Maintenance-Free?

Composite garden rooms require considerably less routine maintenance than many traditional timber buildings. They do not need regular exterior painting or staining to preserve the colour of the wall boards.

However, no outdoor building is completely maintenance-free.

Routine care should include:

  • Removing dirt and surface debris
  • Keeping ventilation openings clear
  • Checking the roof and drainage
  • Inspecting doors, windows and connections
  • Clearing vegetation from around the building
  • Checking the supporting base
  • Following the maintenance guidance for the selected model

Regular basic checks will help keep the garden room clean, secure and functioning correctly.

Designed for the British Climate

Garden buildings in the UK must withstand frequent rain, moisture, sunlight, frost and changing seasonal temperatures.

The composite wall boards used within the Seymour Collection are treated with antifungal agents and contain additives designed to reduce the damaging effects of UV exposure and typical British weather.

Product performance will also depend on correct site preparation, assembly, ventilation and routine care.

Straightforward Garden Room Assembly

Ronjack garden rooms use pre-cut components designed to make the assembly process more straightforward.

Selected buildings may be assembled within a day when the site and base have been fully prepared, although the actual installation time will depend on:

  • The selected model
  • The size of the building
  • Ground and weather conditions
  • The number and experience of installers
  • Whether the base has already been completed
  • Additional doors, windows or accessories
  • Any internal fitting-out required

Always follow the assembly instructions supplied with the selected garden building.

Preparing the Site

A stable, level and appropriately constructed base is essential for the performance of any garden room or shed.

Before installation:

  • Measure the available area carefully
  • Allow suitable access around the building
  • Prepare the required base
  • Check drainage around the site
  • Confirm access for delivering the components
  • Review the complete product dimensions
  • Check any location-specific requirements
  • Plan electricity or other services in advance

The appropriate base will depend on the building model, ground conditions and intended use.

Choosing the Right Composite Garden Room

When comparing composite garden rooms, consider more than the external appearance.

Important factors include:

  • Available garden space
  • Internal floor area
  • Intended use
  • Door and window positions
  • Storage requirements
  • Access and security
  • Ventilation
  • Base requirements
  • Assembly requirements
  • Available colours and finishes
  • Optional accessories

Browse the composite garden rooms and sheds below to compare the available dimensions, layouts and specifications.

Whether you need a garden home office, outdoor relaxation space or durable storage building, LL Plastic can help you identify the most appropriate option from the range.
