Submission Requirements

There are four elements to the design submission, each of which should bear the Unique Registration Number (URN) only. Entrants should refer to the Anonymity requirements and submit the following material digitally:


A maximum of 3x landscape sheets (equivalent to A3 in PDF format only) to comprise:

Sheet 1 & 2 :

The layout of the sheet/s are left up to competitors' discretion however please consider including a contextual site plan to show the main features of the design including proposed wider linkages for public access; diagrams and sketches and an explanatory summary from the written design statement. Please demonstrate clearly the main characteristics of the scheme.

Sheet 3: 3D Concept Visualisation

The proposals should be presented in a clear and succinct manner to enable Evaluation Panel members to readily understand the essence and design drivers behind the scheme.

Please note that the submissions may be viewed on a tablet, laptop or large screen and may also be printed out at A3 for the purposes of assessment, so this should be taken into consideration when putting together the submission.

The URN should be prominently displayed on the front face of each design sheet in the top right hand corner, together with the order in which the sheets should be viewed (1 of 2 etc).

Physical architectural models will not be accepted as part of the Phase 1 submission. However images of models used to develop the design proposal may be included on the design sheet(s).
