Where we started
The brief
Oliver's garden in Beckenham has a garden room at the far end with a seating area in front of it. Oliver wanted a pergola over that area with a see-through roof, so the space is covered but still bright.
That meant a custom-built structure rather than a kit, with a clear roof, proper rainwater drainage and lighting built in. It is a good example of the pergolas in Beckenham we design and build.

What it cost
This pergola came to just under £8,000 including VAT, supplied and installed in three days. That covers the fully custom timber frame, the clear polycarbonate roof, the guttering and the lighting. The polycarbonate sheets alone were around £3,000. A pergola without a roof costs considerably less. See our pergolas in Beckenham page for other options.

Questions
About pergolas with polycarbonate roofs
Thinking about something similar? These are the questions we hear most.
How much does a pergola with a roof cost in Beckenham?
Oliver's fully custom pergola in Beckenham BR3 came to just under £8,000 including VAT, supplied and installed in three days, including a clear polycarbonate roof, guttering and lighting. The roof sheets alone were around £3,000, so an open pergola without a roof costs much less.
Why choose a polycarbonate roof for a pergola?
Clear polycarbonate keeps the rain off but lets the daylight through, so the area under the pergola stays bright. It is lighter than glass, strong and well suited to garden structures.
Does a covered pergola need guttering?
Yes, in most cases. A solid roof sheds a lot of water, and guttering collects it and carries it away so it does not pour onto the seating area or the ground beside it.
Can you add lighting to a pergola?
Yes. We installed lighting on Oliver's pergola so the space can be used in the evenings. See our garden lighting in Beckenham.
How long does it take to build a custom pergola?
Oliver's pergola, with its roof, guttering and lighting, took three days from frame to handover.
Do you build pergolas near Beckenham?
Yes, including Bromley, West Wickham, Penge and Elmers End. See all our landscaping in Beckenham.
