And the resurgent demand for space means the nine major regional cities outside London are on course for their highest take-up in five years in 2013.
The Big Nine report from property consultant GVA James Barr comes as separate research underlines a revival of property construction. Deloitte's UK Cities Crane Survey notes that three office developments in Glasgow and nine projects in the Scottish capital have broken ground in the last year.
GVA James Barr cited two major deals in Glasgow as it measured the take-up in the city centre at 143,399 sq ft in quarter three - Skyscanner's move to 10,850 sq ft space at 151-155 St Vincent Street and the Atos occupancy of 36,500 sq ft at Capella.
The increase represented the highest quarterly advance in Glasgow in three years and was significantly up on the five-year average of 107,246 sq ft.
Quarter three also saw take up in the Scottish capital almost double to 149,609 sq ft.
The five-year quarterly average is 127,734 sq ft.
BNY Mellon moved into one building at Capital House at Festival Square by snapping up the remaining 54,600 sq ft, and PwC took 32,000 sq ft of the Atria One building on a 20-year lease.
Alison Taylor, offices director at GVA James Barr, said confidence was rebounding in Glasgow after trailing off in late 2011, when the double-dip recession and the eurozone crisis forced occupiers to sit tight. More broadly, she said occupiers are taking confidence from signs of economic recovery.
Ms Taylor said: "As occupier confidence increases and take-up of Grade A space gathers pace again, new speculative development is underway again in Glasgow. For instance, Mountgrange and M&G are building 143,000 sq ft of new Grade A at 1 West Regent Street and construction work is also underway at sites owned by Abstract and BAM. It is also encouraging to see out-of-town take-up rise above the five-year quarterly average with 151,000 sq ft in Edinburgh and 55,845 in Glasgow."
Ms Taylor noted there is a "weight of money out there" for investment in building commercial property. Citing a move back to property from equity and gilts, she said institutions, wealthy individuals and overseas investors are keen to act while Grade A space remains in short supply.
At the same time, Ms Taylor said take-up is being driven by changing occupier priorities, citing the importance of energy performance ratings and demand for "agile" workspaces.
GVA James Barr noted an increase in take-up of space at out-of-town sites such as Edinburgh Park, where Sainsbury's Bank has taken 83,000 sq ft and insurance broker Jardine Llyod Thomson 33,784 sq ft. It put the growth down to cheaper rents compared with the city centre.
Meanwhile, Deloitte said the resurgence in property investment in Edinburgh has seen investors spend £55 million on office buildings in the first half of 2013, compared with £26m in all of 2012. In Glasgow, it said the three office developments now underway would ease the "headache" caused by a lack of Grade A office space in the city.
