Do EDDC consultants know how long their piece of string is?

Freedom of Information request on “What Do They Know” website:

Dear Ms Symington,

I would like to make a formal request under the Freedom of Information Act 2000. I am also making this Request under the Environmental Impact Regulations 2004 which require disclosure on the part of Local Authorities.

1) The Davis Langdon report to Cabinet of 17th July 2013 states the following:
“3.4.3 The current gross internal floor area totals some 7,722 m2, with the former Hotel providing 5,784 m2 and the Office Extensions 1,938m2.” http://eastdevon.gov.uk/media/1183866/ca…

This is also referred to in an earlier FOI Request, where you state:
“The floor space area was calculated by an independent consultant and cross-checked with the Display Energy Certificate (DEC).” https://www.whatdotheyknow.com/request/c…

2) The Valuation Office website states the following:
“Address of property: KNOWLE THE, STATION ROAD, SIDMOUTH, DEVON, EX10 8HL
“Total area: 4871.85 [sqm]”
http://www.2010.voa.gov.uk/rli/en/basic/…

I would be grateful if you could provide an explanation for the apparent discrepancy and provide me with evidence as to how the actual floor space at Knowle is calculated.

Thank you.

I look forward to hearing from you.

Yours sincerely,

Jeremy Woodward
