Custom pergola and composite decking in Beckenham
Carmel's back garden in Beckenham, towards Bromley, had an old deck across the back of the house. We removed the old deck and its frame, supplied and fitted around 50m² of new composite decking with a step, built a custom 8m x 4m pergola on site over it, and supplied and fitted around nine closeboard panels on concrete posts and concrete gravel boards down the side. Carmel painted the pergola afterwards. Around 10 days, £18,000 all in, including VAT.

Where we started
The brief
Carmel's garden in Beckenham, on the Bromley side, had an old deck along the back of the house that had come to the end of its life. The aim was a bigger, low-maintenance outdoor room: a new deck, a pergola big enough to shade it and new fencing down the side.
Rather than an off-the-shelf kit, the pergola was designed and built on site to fit the full width of the house. It brings together the decking in Beckenham, pergolas in Beckenham and fencing in Beckenham we install.

Questions
About custom pergolas and composite decking
Thinking about something similar? These are the questions we hear most.
How much does a composite deck and pergola cost in Beckenham?
Carmel's project in Beckenham BR3 cost £18,000 including VAT for removing the old deck, around 50m² of new composite decking with a step, a custom 8m x 4m pergola built on site and around nine closeboard fence panels on concrete posts, done in about 10 days.
Can a pergola be made to measure?
Yes. This one was custom built on site to 8m x 4m so it spans the full width of the deck along the back of the house, rather than using a fixed-size kit.
Can I paint the pergola myself to save money?
Yes. Here Carmel painted the pergola after we built it. We can leave it ready for painting or finish it for you.
Why choose composite decking?
Composite decking does not rot, splinter or need yearly sanding and staining, so it stays looking good with just an occasional wash.
Why use concrete posts and gravel boards for fencing?
Timber posts and boards rot at ground level first. Concrete posts and gravel boards do not, so the fence stays straight and only the panels ever need replacing.
Do you build decks and pergolas near Beckenham?
Yes, including Bromley, West Wickham and Shortlands. See all our landscape gardeners in Beckenham.
