I am finally going to retire and am selling my home office profession grade desk that is in very good condition. The dimensions are 102" by 66". My home office is roughly 13.6' by 10' and it fits very nicely with lots of room to spare. The desk has three file drawers and two smaller drawers for pens etc..
As you can see in the picture, there are cupboards over top a portion of the deck for books etc..
