FAQS

Do I need planning permission?

Why choose ground screws?

For more information, click here.

Ground screws are a modern alternative to traditional concrete foundations. They offer several benefits:

  • Quick installation with minimal ground disruption
  • No need for excavation or curing time
  • Environmentally friendly and removable if needed
  • Ideal for sloped or uneven ground

They’re particularly well-suited to light gauge steel structures due to the precision and load-bearing performance they provide.

Can my building go on an existing concrete base?

Yes – if your concrete base is level, structurally sound, and appropriately sized, your light gauge steel building can be installed directly onto it.

What guarantee do you provide?

Our light gauge steel frameworks come with a lifetime guarantee, giving you peace of mind in the strength, durability, and longevity of your structure. Other components may have their own specific warranties—please speak to your sales representative for full details.

Do you offer erection/installation of the buildings?

Yes. We offer a flexible range of services to suit your needs:

  • Supply-only – ideal for those managing their own build or working with contractors
  • Bronze Package – frame erection only
  • Silver Package – we deliver a fully weather tight shell, including the frame, panels, windows, doors, and roofing, making the building ready for internal works
  • Gold Package – full build including internal fit-out (subject to specification)

Do you supply the necessary fixings?

Yes, we can supply all required fixings, fasteners, and structural connections. Please speak with your sales representative to ensure you receive everything needed for your project.

What are light gauge steel buildings made from?

Our buildings are constructed using precision-engineered cold-formed steel sections. These are lightweight yet incredibly strong, non-combustible, and resistant to rot, pests, and warping—unlike timber.

How do you overcome thermal bridging in steel construction?

Thermal bridging occurs when heat transfers through materials with high conductivity, such as steel. To mitigate this, we use a layered construction method that includes:

  • High-performance insulation, continuous across surfaces
  • Thermal break barriers and non-conductive fixings where appropriate
  • Rigid and reflective boards to reduce heat loss

This ensures excellent energy efficiency and compliance with modern Building Regulations.

Will I get phone signal?

Yes! This is a common misconception. Our frames do not affect or interfere with your signal at all.

Are your buildings insulated?

Yes, we offer high-performance insulation options suitable for year-round use. Our insulation packages can be tailored to suit garden rooms, home offices, annexes, or commercial applications.

Can I customise the design?

Absolutely. Our systems are flexible and can be tailored in size, layout, finishes, and window/door placements. Whether you’re creating a home office, house, studio, or extension, we’ll work with you to bring your vision to life.

How long does it take to build?

Installation times vary depending on the specification, but generally:

  • Frames can be erected in as little as a few hours, depending on size.
  • Full builds (e.g. Gold Package) can take 1–3 weeks, depending on complexity

How energy efficient are your buildings?

Our systems can meet and exceed current Building Regulations for thermal performance. Paired with our advanced insulation methods, they offer excellent energy efficiency, low running costs, and year-round comfort. A recent EPC on one of our Annexe projects returned an A rating – it doesn’t get better than that!

What is the difference between planning permission and building regulations when it comes to garden rooms and extensions?

Please visit out planning permissions page for more information

Planning Permission

  • Governs:
    Building appearance, size, location, and use
  • Typically required for:
    Larger or more visible garden rooms
    Extensions that exceed permitted development limits
  • Can usually be avoided if:
    The structure is under 2.5m high (within 2m of a boundary)
    It covers less than 50% of your garden
    It’s not used as living accommodation
  • Determined by:
    Your Local Planning Authority

Building Regulations

  • Governs:
    Safety, structural performance, insulation, fire protection, electrics, and more
  • Typically required for:
    Most extensions
  • Garden rooms that are:
    Over 15m² in size
    Intended for sleeping or year-round use
  • May not be needed if:
    The garden room is:
    Under 15m², and not used for sleeping
    Under 30m², more than 1m from any boundary, and built using non-combustible materials
  • Checked and approved by:
    Building Control (either through your local council or an approved private
