Garden Room FAQs
Common Questions About Building a Custom Garden Room in Sheffield
Do I need planning permission for a garden room?
In the majority of cases, garden rooms fall under Permitted Development rights, provided they are single-storey, have a maximum eaves height of 2.5 metres (for flat roofs near boundaries), and do not cover more than 50% of your total garden area. If your plans require formal planning permission (e.g. for a full-time residential annexe or conservation area), we assist with the application process.
Can a garden room be used comfortably in winter?
Yes. Our garden rooms are built with the same high-density PIR insulation, double glazing, and draught-proofing found in modern house extensions. Combined with electric underfloor heating or wall-mounted panel heaters, they remain warm and energy-efficient year-round.
How is electricity connected to my garden room?
We trench a heavy-duty armoured cable underground from your main property consumer unit to a dedicated distribution board inside your garden room, fully tested and certified by our NICEIC-accredited electrical partners.
