We understand that you will be looking to plan the cost of any new lean-to extension into your budget. That is why we will work closely with you to plan and calculate the cost of your ideal home office, living room, or much-needed storage space. As such, the price youโll be quoted will be based on individual requirements and the specific needs you have for your lean-to.
The work we provide may usually be priced at anywhere between ยฃ5,000 and ยฃ30,000. To find out how your new lean-to may therefore fit into your budget, speak with us today.
Every lean-to structure we have for sale is Q-Mark certified. This means you may rest assured that everything from our building techniques to the processes undertaken on our site are overseen and analysed by Exova BM TRADA. This certification panel is widely considered the strictest in the UK, and is held in the highest esteem.
We source our timber from a specially designated site in France, cultivating traditional green oak (Quercus Robur and Quercus Petraea) for this purpose. This beautiful, durable wood is guaranteed to offer you the stunning, hard-wearing results you need for any extension. To ensure sustainability and minimise waste, we will also plant our own trees and ensure they are grown to be as tall and straight as possible.
This means more of the wood can be used in construction, takes up less land, and means we can offer our customers more competitive prices.

Any kit we provide should be sent out to its destination in the UK or the Channel Islands within six to eight weeks of being signed off.
How long it will take to build your lean-to garden room all depends on the size of your chosen kit. For smaller projects, this may take several weeks to a month.
When thinking about how to budget for your new lean-to, there are a few more factors that you may wish to consider:
โ How you intend to use the lean-to (whether as an office, living space, kitchen diner, etc.)
โ The style of the frame or cross-section
โ The type of timber youโd like for the joinery, cladding, and rafters
โ Access and security requirements
If you are in the final stages of selecting your lean-to and havenโt yet considered these factors, there is no need to worry. Our team will be on hand to help talk you through each of them, before finding the best garden buildings or extensions for your budget.
