1. Catch the next wave in architecture, build on water!
Enjoying a central seafront location next to the Market Square, the Allas Sea Pool has transformed an under-used site into a refreshing
recreational oasis to Helsinki’s inhabitants and travellers visiting the city. Using the experience gained in building urban swimming arenas
in Gibraltar, Norway and Denmark, Marinetek developed the Allas concept and broadened the scope yet further, creating The Allas Sea
Pool, a lookout spot and garden-like oasis situated in Helsinki’s southernmost seaside. With its land and sea areas it covers almost a
hectare of the city centre. Combining the lingering Baltic spa tradition and modern urban culture, Allas Sea Pool offers something for
everyone, all year round, able to fit about 3500 people at a time.
Build in co-operation with Bluet, Allas is a great example of a project that combines a new type of exciting urban culture and brings added
value to seafront properties that have gone underused until now. The facility offers a year-round spa, one large freshwater pool and one
freshwater pool for children, both of which are filled with water heated to 27 degrees Celsius. There is also one sea water pool, filled with
purified sea water. All this is topped with magnificent saunas, and a floating deck with a separate lounge and sports areas. Impressive,
huh?
“We are happy to participate in a project that will offer exciting experiences both to the city’s inhabitants and tourists experiencing Helsinki
for the first time. We hope that our project will promote the transformation of Helsinki’s beachfront and speed up its development for urban
recreational purposes,” says Markku Rantanen, Senior Partner at Marinetek.
