Courier Address For Sheffiled

I just applied for Tier 1 Exceptional Talent - TechCity but the form I got after making payment does not have courier address to send the documents. Do you guys know the courier address of Sheffield center? I only got PO Box number address which does not work for courier, they need street address. Kindly help.

Note: I did post this question as a reply in another post but not getting any reply and since the time is running out for me I thought to create this new thread which can help other members to find the correct address for courier in future as well.
