Design reveals what lido in Bristol harbour could look like
The group behind a campaign calling for swimming to be allowed in Bristol docks have revealed their vision for a Copenhagen-inspired lido.
A spacious pontoon would surround the ‘Cumberland Basin Baths’ in the plans drawn by London-based architects Studio Octopi that incorporate a 25m pool and paddling pool with a 50m open water space beyond marked with red buoys.
There would be a refreshment kiosk and changing facilities, with access off Brunel Lock Road.

The company was hired by Swim Bristol Harbour to show what a designated swimming area in the docks might look like. The group is campaigning for swimming to be permitted in the harbourside waters, arguing it would be beneficial for many in the city.
Bristol City Council has said it is exploring the idea of introducing a safe, separate swimming area as part of the proposed Western Harbour development, but has stressed it is currently illegal and unsafe to swim in the docks.
Authorities have issued stark warnings about the dangers of doing so, saying it poses a serious risk and is a very different experience to going in a river or lake. Unlike most popular wild swimming spots around Bristol, the water in the Floating Harbour is regularly tested by Bristol City Council.

Unveiling the lido proposal, Swim Bristol Harbour founder and businessman Johnny Palmer said: “It is clear to me that the city needs more accessible blue space that is free to use, promotes a healthy lifestyle and mental wellbeing.
“Wild swimming has helped countless people over recent years and we want to see these benefits shared with all people of Bristol.
“Marvin’s One City Plan is fantastic and a lido in the Cumberland Basin is entirely within the remit of this – inclusive, accessible, promotes a connection with nature, improves mental health, enhances social capital and is a great form of exercise.”
The architects at Studio Octopi specialise in outdoor swimming facilities and have created a design for baths that float in the water of the Cumberland Basin, rising and falling on piles to adjust to the varying water levels.
Within the pontoon is a 25m pool with a depth of 1.2m formed from perforated steel sides and bottom, as well as a paddling pool. The idea is to let water pass through the sides and base of the main pool – like a submerged colander.
As part of the vision, electricity for small power items on the pontoon would be generated via PV and wind turbines. A bridge and ramp would lead to the main pontoon, with a kiosk for refreshments and tickets. The design would allow for changing cabins and showers within the kiosk or temporary facilities along the harbourside.
The designers say their vision “is a real opportunity for Bristolians to take ownership of a small piece of the dock for community purpose and benefits”.
Despite bylaws prohibiting anyone from entering the water in the docks, Swim Bristol Harbour members have staged a number of swims to draw attention to their campaign.
They believe it can be managed safely and want to see small-scale, controlled swimming areas permitted.
“Within the Swim Bristol Harbour group, we have qualified lifeguards, experienced wild swimmers, swim coaches, lawyers and paramedics,” says Palmer, who also owns Warleigh Weir, a popular swimming spot near Bath.
“We have a clear and workable plan that gets us from where we are to Bristol being an international leader in urban swimming.”
