How Much Does A Garden Room Cost?

The most popular question after we call to your home and meet with you is “how much is a Garden Room going to cost me?” In this week’s blog, we are going to try to give you the best answer we can to tackle the question of how much does a Garden Room cost. There are a few factors that go into Garden Room pricing so read on to get a better understanding.

Garden Room Pricing for Standard Package

Let’s start looking at Garden Room pricing with our standard package and the first thing to look at is what’s included in the package, outlined below.

  • the full building, including foundations
  • windows and doors
  • roofing membrane
  • internal electrics, including downlighters and brushed chrome double sockets
  • insulation in walls, floor and ceiling
  • walls plastered and skimmed
  • internal flooring including skirting board

Garden Room Costs Per Square Meter – Standard Package

Now that we know what the standard package contains it’s time to have a look at the pricing per meter square. Our Garden Rooms cost €1,250 per square meter before VAT. So, if you are going for a 15 square meter Garden Room (like the CUBE 15 for example) or a 25 square meter Garden Room (CUBE 25) you are going to see the cost of the room increase accordingly. If we compare this to a standard house extension, you could pay between €2400 – €2600 per square meter before VAT. If you’re torn between a Garden Room or an extension you can read more about the differences between a Garden Room and building an extension to get a better idea of what each entails.
