How long does a garden room take?

By the Garden Room Guide Team · Updated

The short answer

Once your slot comes up, a prefabricated garden room can be installed in a day to two weeks, and a room built on site typically takes 2 to 4 weeks. From first quote to using the room, allow a couple of months, more in busy seasons, because of quotes, lead times, the base and electrics.

How the build type changes it

Build typeTime on site
Craned-in modular roomHours, once the base is ready
Prefabricated panelsA day for small rooms, up to a couple of weeks
Built on site from raw materialsTypically 2 to 4 weeks

Add 1 to 3 days for the base, longer for concrete that needs to cure, and a few days for electrics and finishing if they're separate.

What causes delays

  • Lead times. Popular companies book up weeks or months ahead, especially in spring.
  • Access. Narrow side passages mean carrying everything by hand.
  • The base. Poor ground, slopes or drains in the way.
  • Electrics. If the electrician is booked separately, the room can sit finished but unpowered.
  • Weather, for concrete bases and on-site builds.

When to order

Many people decide in spring and want the room for summer, which is when lead times are longest. Ordering in autumn or winter can mean shorter waits and a room ready for spring.

Yes. Prefabricated rooms in particular go up quickly in most weather. Concrete bases and on-site builds are slower in very wet or frosty spells.
