Cardiff (Cardiff Daily) August 18, 2026 – Cardiff Council has formally approved planning consent for a massive 33-storey co-living skyscraper proposed by the Watkin Jones Group on Custom House Street, marking a pivotal shift in the capital city’s architectural profile. The high-rise scheme will deliver 400 purpose-built co-living rooms designed to foster communal living while providing private, fully furnished accommodation. According to the planning application submitted by the developer, co-living developments are specifically structured to accommodate residents who share common areas, such as kitchens and living spaces, while maintaining private en-suite bedrooms. The document further outlines that the co-living concept promotes community living, fostering social interaction, collaboration, and shared resources. It notes that co-living spaces are often targeted at younger professionals or transient workers and typically offer flexible lease terms, fully furnished rooms, shared amenities, and a single monthly payment covering rent and utilities.

The decision to approve the planning application follows extensive discussions within Cardiff Council’s planning committee regarding high-density urban housing, city centre rejuvenation, and skyline management. Located along one of Cardiff’s busiest arterial routes, the Custom House Street site will transition from an underutilised plot into a prominent tower.

The Watkin Jones Group, a major developer specializing in student accommodation and build-to-rent schemes, submitted detailed plans detailing the building’s design, environmental efficiency, and transport integrations.

The developer outlined that the high-density model fits strategic urban planning goals by directing residential density into central urban areas served by public transport networks, thereby mitigating suburban sprawl.

During the planning committee review, officers assessed the proposal against current national planning guidelines and local development plans.

Planning officials noted that while the structure represents a significant increase in height compared to adjacent properties, the location within the central business district makes high-density development appropriate.

The scheme includes communal facilities such as dedicated co-working areas, gym facilities, rooftop terraces, cinema rooms, laundry spaces, and secure cycle storage. The building operates on a zero-parking design model, encouraging active travel and reliance on local bus and rail transport links located nearby at Cardiff Central station.

The public debate surrounding the proposal highlighted differing views amongst local stakeholders. Environmental officers highlighted the inclusion of low-carbon building systems, solar panel arrays, and high-performance insulation aimed at meeting stringent sustainability metrics.

Conversely, local heritage groups and nearby residents raised observations regarding the visual impact on surrounding historic assets, including nearby listed structures. Planning officers confirmed that compensatory architectural design measures and spatial offsets were incorporated to ensure the structure integrates into the evolving city centre landscape without causing unacceptable harm to surrounding heritage assets.

Construction on the Custom House Street project is anticipated to commence following the discharge of final planning conditions and technical approvals.

The project forms part of a broader trend across major cities in the United Kingdom, where co-living is increasingly viewed by developers and local authorities as an alternative housing model for young workers facing rising urban housing costs.

What Is the Co-Living Model Approved by Cardiff Council?

The co-living model approved for Custom House Street represents a specialized form of residential accommodation that bridges the gap between traditional private rentals and high-density purpose-built student accommodation.

Unlike traditional flats, co-living units provide residents with private, fully furnished en-suite rooms, while larger living facilities are shared across the building.

The planning documentation submitted for the scheme clarifies the core ethos of the development model:

“Co-living developments are designed to accommodate residents who share common areas, such as kitchens and living areas, while having private ensuite bedrooms. The co-living concept promotes community living, fostering social interaction, collaboration, and shared resources. Co-living spaces are often targeted at younger professionals or transient workers and typically offer flexible lease terms, fully furnished rooms, shared amenities and a single monthly payment.”

Under the approved management plan, the single monthly payment paid by tenants encompasses rent, high-speed internet, utility bills, maintenance services, and access to all internal communal facilities.

The model relies heavily on professional on-site management, with round-the-clock staff provided to oversee security, facility upkeep, and community programming.

Why Was Custom House Street Chosen for a 33-Storey Tower?

Custom House Street was selected due to its central location, existing transport links, and proximity to major employment hubs in central Cardiff.

The site is situated within walking distance of Cardiff Central railway station and major commercial centers, placing it within an area designated by planning policies for high-density redevelopment.

Urban planning assessment reports submitted to Cardiff Council highlighted that high-rise development along Custom House Street aligns with the council’s wider strategy to concentrate residential growth within the urban core.

By positioning high-density housing near principal transport routes, the planning strategy aims to minimize private car usage and maximize pedestrian access to retail, leisure, and commercial services.

Furthermore, the surrounding urban context has seen incremental tall-building developments over the past decade. The 33-storey height was deemed acceptable by planning officers on the basis that the tower serves as an architectural anchor within the tall-building zone of the city centre.

How Did Local Authorities and Residents React to the Application?

The planning consultation process yielded a range of representations from local residents, heritage bodies, and commercial stakeholders.

Members of the planning committee debated the scale of the tower, questioning whether a 33-storey structure was proportionate to the immediate streetscape.

Heritage advocates expressed reservations regarding the visual presence of the tower relative to nearby historic buildings, urging council members to consider the preservation of local character.

In response to these concerns, design modifications were made to the building facade to create a visually distinct base, middle, and crown structure, reducing the perceived bulk from street level.

Supporters of the development, including regional business groups, welcomed the consent, noting that the addition of 400 residential rooms would increase footfall for local businesses and support the night-time economy.

Planning officers ultimately recommended the application for approval, concluding that the public benefits of providing additional housing units, redeveloping an underutilised site, and contributing to urban density outweighed the visual and environmental impacts identified during the consultation phase.

Background of the Particular Development

The development of the 33-storey tower on Custom House Street occurs within the context of significant structural changes in the housing market across Wales and the wider United Kingdom.

Over the past decade, Cardiff has experienced sustained population growth driven by expanding higher education institutions, growing commercial sectors, and increased inward migration of young professionals.

This demographic growth has placed sustained pressure on the capital city’s private rented sector. Traditional housing stock, such as houses in multiple occupation (HMOs) in suburban areas like Cathays and Roath, has historically absorbed much of this demand.

However, Cardiff Council has increasingly sought policies to manage HMO density in suburban neighbourhoods while encouraging purpose-built high-density residential developments in the city centre.

The Watkin Jones Group has been an active developer in Cardiff’s residential sector, previously completing several high-density student accommodation schemes and build-to-rent properties across the capital.

Co-living has emerged as an extension of these residential models, adapted specifically for early-career professionals, healthcare staff, and technology sector workers seeking central accommodation without long-term lease commitments or high upfront setup costs.

The site on Custom House Street had been subject to various redevelopment proposals over the preceding years. Previous iterations and initial land-use studies considered hotel, office, and standard student accommodation formats before the developer finalized the co-living concept.

The approval of this 33-storey scheme establishes a benchmark for co-living density in Wales, following similar high-rise approvals in major English cities including London, Manchester, and Birmingham.

Prediction: How This Development Can Affect Young Professionals and the Local Area

The approval and eventual completion of the 33-storey co-living skyscraper on Custom House Street is expected to exert several distinct impacts on young professionals, local businesses, and the broader urban landscape of Cardiff.

For young professionals and transient workers in Cardiff, the development will introduce a new housing typology into the central rental market.

The inclusion of 400 fully furnished units with flexible lease structures provides an alternative option for individuals relocating to the city for short- to medium-term employment contracts, healthcare rotations, or corporate graduate schemes.

By bundling utilities, internet, and amenity access into a single monthly payment, the model reduces upfront financial barriers such as purchasing furniture or managing multiple utility contracts.

However, the overall affordability of the units relative to traditional shared flats will depend on prevailing market rental rates set by the operator upon completion.

For local businesses and the central Cardiff economy, the arrival of 400 residents on a single site will generate concentrated daily footfall along Custom House Street and adjoining commercial zones. Nearby retail establishments, cafes, restaurants, and convenience services are likely to experience increased trade, particularly during evening and weekend hours.

The increased local population density supports council objectives regarding the creation of a vibrant, 24-hour city centre economy.

Regarding the wider housing market and city infrastructure, the concentration of 400 individuals within a purpose-built facility may alleviate a portion of the rental demand currently directed toward suburban family housing stock and traditional HMOs.

From an infrastructural perspective, the zero-parking design of the building will limit additional vehicle traffic in the city centre, though it will increase pedestrian density and utilization of local public transport services at Cardiff Central station and nearby bus interchanges. Visually, the 33-storey structure will permanently alter Cardiff’s skyline, likely setting a planning precedent for future high-rise residential proposals within the central area.
