Plans to build a huge tower in the centre of Cardiff which will include hundreds of new homes have been revealed. A pre-application publicity and consultation document has been launched by REAP 3 Limited, a company that wants to transform land at Central Square in the centre of the capital.

The site - located between Wood Street and Rose Lane - already has full planning permission for a 35-storey, mixed-use development which will provide commercial use on the ground floor and residential space above. REAP 3 Limited, a subsidiary of Bluecastle Capital, whose chief executive is Cardiff-born Ed Williams, is now preparing a new planning application for the site.

The new plans are seeking to build upon the success of the wider Central Square area, and propose a 50-storey high quality mixed-use development that will create a new landmark at what is described as an "important location" in Cardiff.

In total the new building, which would be the tallest in Wales, dwarfing the 29-storey Meridian Tower in Swansea, will include 528 new homes for rent along with a wide range of residential amenities, a bike hub and flexible non-residential uses. 344 of the apartments will be one-bedroom, while 184 will boast two bedrooms.

According to the design and access statement that forms part of the plans, the REAP 3 Limited says: "The site is located at a key junction in Cardiff city centre, positioned between Cardiff Central Station and the Principality Stadium.

"It forms part of a major pedestrian route connecting transport, retail, and civic destinations, and experiences extremely high footfall, especially on matchdays when the stadium hosts up to 80,000 visitors.

"This prominent setting places strong demands on the public realm to be resilient, legible, and welcoming, supporting both everyday use and peak crowd conditions. The proposal responds by embedding nature-based solutions, enhancing wayfinding, and delivering a landscape that supports climate resilience, biodiversity, and cultural identity."

The plans add: "The success of the project will rely heavily on the quality of both the service provided and the environment created. High standards of design and finishes will be complemented by the thoughtful arrangement of spaces to enhance the resident experience. The entrance will be designed to ensure a secure, high-quality entry experience."

A full planning application will be submitted to Cardiff Council in due course. Residents are invited to read further details of the plans and submit any feedback they may have.
