The new library, situted on the southern end of the Hayes, features the latest energy saving systems for lighting and heating and is part of the £675m St David's 2 development
There are excellent views across the city from the floor to ceiling windows in the library. These are mostly glazed with coloured glass panels to minimise solar heat gain.
The library features several study spaces, reading areas and meeting rooms, all of which are furnished with funky items in bright colours
Councillor Nigel Howells said he was particularly pleased with the addition of this baby grand piano to the library because it had been one of his suggestions.
All of the shelves and furniture, including this enormous Big Brother-esque comfy chair and foot stool, were designed and produced by Remploy, the company which helps people with disabilities secure employment.
The children's library is situated on the mezzanine floor and its shelves feature cupboards containing toys and books.
The new library was certainly a hit with visiting children from Lansdowne and Radnor primary schools who listened intently to a tale about liver and onions in the childrens' floor's storytelling area.
Morgan Murphy (left), nine, and Connie Merinetto, eight, from Radnor primary school liked the new library's bright colours and hidden toys.
Ten-year-old Ahmed Ahmed from Lansdowne primary said he would be telling all his friends to go to the new library.
Ten-year-old Bilal Abdi and his mother Suhair Hassan thought it was a very relaxing and spacious.
