Choosing the Right Garden Room Size

A well-sized garden room should feel proportionate to your garden while providing enough usable internal space to function comfortably. Below is an overview of our general size categories.

Mini Garden Rooms

Our Mini Garden Rooms are ideal for compact gardens or focused, single-purpose use. These smaller structures maximise efficiency without compromising on insulation or quality.

Typical uses:

  • Compact home offices
  • Study pods
  • Hobby spaces
  • Reading rooms
  • Small creative studios

Ideal for:

  • Gardens with limited depth
  • Terraced and semi-detached properties
  • Clients seeking lower overall investment

Even at a smaller footprint, Mini rooms include:

  • Full wall, floor and roof insulation
  • Double glazing
  • Premium electrics
  • High-quality cladding options

A Mini garden room offers separation and focus without overwhelming your outdoor space.

Small Garden Rooms

Our Small Garden Rooms offer additional flexibility while remaining proportionate to suburban gardens across Lewisham, Bromley and surrounding areas.

Suitable for:

  • Dedicated garden offices
  • Yoga or wellness rooms
  • Compact home gyms
  • Creative studios
  • Multi-use hobby spaces

Benefits of choosing a Small size:

  • Space for desk plus storage
  • Room for fitness equipment
  • More natural light opportunities
  • Greater layout flexibility

These rooms provide enough internal space to feel comfortable for daily use while maintaining strong value and manageable build time.

Medium Garden Rooms

Our Medium Garden Rooms are among the most popular options. They provide generous internal space for multi-use functionality without entering full annexe territory.

Perfect for:

  • Combined office and gym
  • Larger home workspaces
  • Studio plus storage
  • Teen hangouts
  • Business consultation rooms

Advantages of a Medium garden room:

  • Clear zoning within the space
  • Comfortable ceiling height and proportions
  • Increased resale appeal
  • Adaptability over time

Medium sizes allow homeowners to create a room that can evolve, for example from office to guest space or gym.

Large Garden Rooms

Our Large Garden Rooms are designed for homeowners who want maximum space, flexibility and long-term value.

Ideal for:

  • Multi-room layouts
  • Large gyms
  • Studio plus bathroom
  • Family entertainment spaces
  • Live-work combinations

Large garden rooms offer:

  • Room separation options
  • Space for WC installations
  • Enhanced property appeal

These structures require careful planning to ensure compliance and proportionality, and we provide clear guidance throughout the process.
