Garden Room Price Calculators
Looking for an idea of garden room price? You have come to the right place! We have created three price calculators which will quickly tell you what the average price is for different size garden rooms in different specification levels. They will give you an idea of cost, and allow you to set your budget.
Jump to our three price calculators:
Workings:
We surveyed the companies we write about and asked them for prices. We also trawled through supplier websites noting prices for different sized garden rooms. Segmenting the prices by the construction specification. We combined this data into a spreadsheet which forms the basis of these calculators.
Using the price calculators:
Our calculators allow you to select common widths & depths of garden room (you can get bigger!). You can specify the size in 100mm increments. You will find that some companies only work in 500mm increments.
The prices quoted are based on the market average. In the calculator notes, we list the minimum & maximum prices we found in our research. Your choice of design features will affect the price you ultimately pay.
Standard Specification Calculator
Use the sliders to select the size of room you are interested in:
Notes:
This calculator offers the average prices for entry-level garden rooms. With this specification level, you can expect a fully insulated, double glazed building, with
- Foundation - this spec often includes the foundation system, some companies ask for a concrete slab to be installed prior to delivery, which would be an additional cost.
- Roof - often an insulated panel system that forms the internal ceiling finish or Asphalt roof coverings used.
- Doors & Windows - softwood doors and windows are commonly used, with uPVC being an option on some designs. Typically single doors or French doors are offered.
- Cladding - treated softwood claddings some with painted finishes or Thermowood or Larch.
- Interior - softwood tongue & groove or MDF sheets. Often left for your own decoration.
- Floor - softwood floorboards or OSB floor deck for your own finish. Some offer laminate.
- Electrics - pre-wired with minimal light & power points. You will have to budget for the cost of connecting the electrics to the mains supply.
- Installation - prices include installation and VAT. You may find there is a delivery charge.
Our research found that companies are charging between £750 and £1,500 per square meter for this specification. Our calculator uses the market averages from our survey.
Medium Specification Calculator
