>What is the most important for you 1) office environment OR 2) company culture?
Office environment is either a subset of company culture, else has massive overlap with it.
If you are asking for comparison between company culture and physical work environment (i.e. the tangible sites, facilities and decoration) again there is massive correlation/causation between the two, and are very intertwined subjects - Here is a fairly comprehensive overview of the current literature:
THE IMPACT OF THE PHYSICAL WORK ENVIRONMENT ON ORGANIZATIONAL OUTCOMES: A STRUCTURED REVIEW OF THE LITERATURE - Paul Kegel
http://jfmer.org/doi/full/10.22361/jfmer/76637
'Office environment and Company Culture' are bundled together for the above reasons. - In summary, it isn't really possible to compare as an 'either/or'.
Data would be too noisy and interrelated to split, and if split would have little value that could be derived anyway.
