This project was the result of a competition to renovate or rebuild the Young Vic Theatre, which was originally built about 35 years ago as a temporary structure on a bomb site on the Cut, London SE1. The competition entry aimed to maintain the aura of the theatre, whilst significantly improving the quality of the spaces, the working conditions for the company, and the flexibility of the types of shows that could be put on.
 
This project was constructed to an extremely tight budget of £7million, and the outturn [[Cost_of_structural_steelwork|cost]] matched that budget. To achieve this, finishes were kept to an absolute minimum, which means that all the structure is expressed, and the detailing had to be carefully considered. Where [[Fire_protecting_structural_steelwork|fire protection]] is required, [[Fire_protecting_structural_steelwork#Intumescent Coatings|intumescent paint]] is used. Keeping parts of the original structure kept costs down, and is good for [[Sustainability|sustainability]].
 
The general principle for the [[Design|design]] of the [[Leisure_buildings#Theatres and auditoria|auditorium structures]] has been to minimise additional vertical loads on the existing walls and their foundations, and to avoid alterations to the raft.
 
This roof is constructed using deep structural steel [[Trusses|trusses]] which span from east to west. They are supported by a steel truss on the east side and steel [[Steel_construction_products#Standard open sections|columns]] on the west side. Steel [[Steel_construction_products#Standard open sections|beams]] span between the [[Trusses|trusses]] and support [[Steel_construction_products#Decking for floors|metal decking]] with concrete topping, which provides the [[Acoustic_performance_of_floors#Composite floor on steel beams|acoustic insulation]]. These [[Steel_construction_products#Standard open sections|beams]] also provide lifting points for the theatre.

The [[Trusses|trusses]] support the 'egg crate' technical gallery that is constructed using structural steel. The new 'egg-crate' structure supports balustrading and lighting bars, and provides access to the lifting positions. Two central [[Bridges|bridges]] are demountable and may be installed to run either north-south or east-west across the [[Leisure_buildings#Theatres and auditoria|auditorium]]. The [[Bridges|bridges]] are designed as steel ladder structures with lightweight timber floors. [[Trusses#Vierendeel trusses|Vierendeel bracing]] provides [[Concept_design#Structural options for stability|lateral stability]] to the bridge structures.
 
A new technical gallery around the periphery of the [[Leisure_buildings#Theatres and auditoria|auditorium]] is constructed using structural [[Steel_construction_products#Standard open sections|steel beams]], with the inner edge hung from the roof structure and the outer edge supported on the existing wall. The new front of house facilities in this area are generally constructed using a steel frame with timber joists and ply decking for the flooring and roof construction.
 
A structural steel [[Portal_frames|portal frame]] is provided from level two to the roof for the back of house office facilities at the south of the site.

==Judges' comments==
This extremely complex and intricate re-build presented tough challenges to the whole team.
 
Steelwork frames much of the new building, including the new roofs, and particularly those above the theatrical spaces which are very flexible and adaptable. The cost constraints required ingenious solutions.
 
The Young Vic's traditional stimulating ambience has been maintained for the satisfaction of the lively audiences.
