Garden Room Prices & What’s Included

Transparent pricing, tailored to you.

Garden Room Costs:

if you're considering a garden room, one of the first questions you're likely to ask is: how much does it cost? After all, a garden room is far more than just a traditional shed or summerhouse.

With careful planning, it can offer functionality and performance that rivals a full extension - without the hefty price tag or hassle. But before you start designing your dream garden room, it's important to understand the typical costs involved.

Once you've determined the purpose of your garden room - whether it's a workspace to eliminate commuting costs or a peaceful retreat to escape the stresses of daily life - you can make informed design choices that will impact the overall cost of the project. 

When it comes to garden rooms, the size of the building is a key factor that influences its cost. If you're considering a Locks Garden Rooms, the price will be tailored to your specific design choices and since all our designs are bespoke, we don’t provide pricing on our website.

We believe in crafting each project from the ground up, customising the finish to align with your unique taste and budget. As a rough estimate, most projects typically range between £1,300 and £1,700 per square meter, including VAT. However, this can vary significantly depending on factors such as size, cladding choices, and glazing options.

Rest assured, our pricing always encompasses a comprehensive turnkey solution. This includes everything from foundations to electrical connection to the house, along with full professional decoration.

We would then ask for weekly instalments to cover materials and labour.
