A "striking piece of architecture" will form part of the new Swansea arena development, housing a pavilion cafeteria.
Planning documents submitted by Buckingham Group Contracting, on behalf of Swansea Council, show how the pavilion-style attraction will stand close to Swansea's eagerly anticipated new 3,500 capacity indoor arena.
And officials say its "curved skin" that will be illuminated by more than 70,000 programmable LED light bulbs.
The building, with a "timber frame and strong green credentials", will have an area of outdoor seating under canopies so guests can fully enjoy the experience of being in the 1.1-acre coastal park. There will be indoor seating too.
Its position and height, around 6m above Oystermouth Road on top of a two-deck car park, will allow views of Swansea Bay and the sea in the distance and the Swansea cityscape.
Plans for the oval and wedge-shaped building include a 94 sq m café-restaurant, a kitchen plus internal and external toilets.
The designs feature wood, local stone, stainless steel, aluminium and a solar roof. Natural lighting and ventilation will be used wherever possible. Bosses also promised that lighting will be low-energy and light pollution will be minimised.
It will be positioned "to allow covered external seating beneath canopies to fully enjoy and be part of the park experience" and the pavilion's position and height will also "allow distant views out to sea, and over the townscape to the north and west", the plans stated.
Planning documents read: "This is a very large building so the main glazing and views out of the Pavilion will be to the west and south.
"This will give the best views out over the landscaped roof park, and views out towards the sea.
"The pavilion cafeteria is designed to act as a striking piece of architecture within the roof top park, without creating a dominant feature vying against the arena’s architectural form.
"It will be fabricated using offsite methods as far as possible, with a sustainable shell structure, renewable energy generation, and ‘green’ interior climate management, to minimize its environmental ‘footprint’."
A glimpse into Swansea's future...
Swansea Council leader Rob Stewart said: “The pavilion is another striking addition to the city’s dramatic £1bn regeneration story. It’s designed to be welcoming and will be publicly accessible to all.
“It will add a dramatic focal point to this area, the first major new parkland in Swansea since Victorian times.
“The pavilion will complement the arena’s architecture and will benefit from its own renewable energy generation and green interior climate management to minimize its environmental footprint.”
The plans form part of the £135m Swansea Central Phase One scheme, a catalyst for wider development on the city’s ongoing £1bn regeneration.
As well as the parkland, parking for around 1,000 cars and arena, phase one includes a landmark bridge now being constructed on site, homes and commercial units.
Funding sources include the council, Swansea Bay City Deal and the Welsh Government.
