Proposed Supermarket 80% bigger than existing

We have recently got together some statistics and information about the proposed size of the Morrisons supermarket and comparing it with other local stores.

The outline planning application includes a 64,000sq ft store for Morrisons which is gross floor space (measured externally) and will include all the ancillary things like offices, storage etc. The existing Morrisons is approximately 36,500 sq ft. which to our calculations make it nearly 80% bigger than existing. We previously thought that the proposed size was about 1.5 times(about 50% bigger.)

The Asda store size in Bishopbriggs including warehouse & office space is 52,000 sq ft. This store is classed as a smaller development whereas the Adsa store in Robroyston is 70,000 sq ft. Deliveries to the Bishopbriggs Asda store are 80 on an average week and 140 during the Xmas week. The residents around the store have enforced timing limits on deliveries with EDC and they are none before 7.00am and after 10.00pm.

Smith Design Associates-Morrisons Architect have a page on their website with 6 other Scottish Morrisons stores that they've been involved with. If you click on each store it give a sq. ft for each and are as follows:
Kilmarnock, Hamilton, Livingston each 85,000 sq. ft
Johnstone 78,000 sq. ft
Giffnock 63,000 sq. ft
Cardonald 62,000 sq. ft
This would make the Giffnock Morrisons store the nearest in size to the proposed one in Bishopbriggs.
