The interviewees included architects, quantity surveyors, contractors, housebuilders and clients. Building was read by 77% of those surveyed - the highest count among the 11 magazines, and 11 percentage points ahead of its nearest rival.
Building was rated most useful by 40% of the respondents – 29 percentage points ahead of the second-placed magazine; 38% said Building was most interesting to read, 28 percentage points ahead of the next title.
Asked which magazine they would choose if they could only read one magazine, 41% said Building – which made it the sector's favourite title by 30 points. Building is also the best place to find a job, says the survey.
The survey found that 78% read at least half of Building – and 38% read all (or almost all) the magazine. On average, readers devote about half an hour to reading each copy; one in two then passes it on to a colleague and one in three keeps it for reference.
Building editor Adrian Barrick said: "I'm delighted with the results of this independent survey, and I would like to thank all our readers for their continuing support. This research follows our success in achieving record levels of subscriptions."
