Scheme location:

Leeds Skelton Lake Services M1 J45, Leeds, West Yorkshire


A ‘new concept’ building design was commissioned by the site developers and owners Extra MSA Group for the new Leeds Skelton Lake Services building at Junction 45 on the M1, located adjacent to Skelton Lake, a 40,000m2 area of ecologically diverse country park, 2 miles southeast of Leeds city centre. To minimise the visual impact of the development the main 5,277m2 amenity building features an over sailing, undulating green roof. The roof is configured in a unique ‘ribbon’ pattern in eleven separate sections. Designed as part of the development’s ‘landscape mitigation and green space strategy’, the living roof and timber eaves closely echo the nearby woodland and lakeside habitat and blends in with the country park backdrop

SuDS features:

  • Wildflower green roof 
  • Tree pits 
  • Detention basin 

Award category:

New commercial development (any scale)

Scheme location:

Middlewood Locks, Manchester


Located at the first locks of the Manchester, Bolton & Bury Canal, the second phase of the £1bn Middlewood Locks mixed-use scheme delivers 546 apartments across 4 new buildings with private podium gardens. Phase 2 of the project (where the blue roof attenuation system is installed) regenerates an area of 6 hectares of brownfield land in Salford. The site discharges to the renovated balancing basins that service the adjacent canals and the River Irwell.  

The extensive soft landscaping and permeable resin bound paving reduces the impact of surface water run-off to less than that of the pre-developed brownfield land.  

SuDS features:

  • Blue roof water attenuation system 

Tree pits:

  • Sedum roof 
  • Permeable resin bound surfacing 

Award category:

New housing development – large (more than ten units)

Scheme location:

Cardiff Centre for Student Life


The Centre for Student Life (CSL) project consists of a new flagship building for Cardiff University and surrounding Park Place public realm improvement works in the centre of Cardiff, with construction works completed in 2022. Arup’s multidisciplinary scope included the Civils and Drainage design, with IBI acting as Landscape Architect. Due to significant constraints within the highway area limiting source control solutions, the team designed a large ‘end of catchment’ rain garden system, including a sediment forebay and below ground storage system which maximise water quantity and quality benefits. The large rain garden (believed to be the largest in Cardiff city centre)

Is prominently visible for pedestrians to obse rve the SuDS feature controlling runoff whilst improving the parks amenity and biodiversity. The SuDS system was designed reduced the outflow into the existing sewer to the greenfield runoff rate , reducing the likelihood of downstream city centre flooding and the risk of overwhelming the sewer during large storm events. The scheme was one of the first schemes to achieve full SAB approval in Cardiff.

SuDS features

  • Sediment Forebay
  • Rain garden
  • Attenuation cells

Award category:

Regeneration and retrofit – small scale (less than one hectare)
