Nigerian is in the process of developing a green certification standard for its buildings inspite of the fact that it is becoming a global phenomenon. In view of this, a green building council has just been established. The aim of this study is therefore to investigate the level of clients demand for green features in office buildings with a view to providing an incentive for prospective developers of green buildings in Lagos. Nigerian data for the study will be from structured questionnaires administered to 250 offices in high rise office buildings within Lagos island of which 193(77.2%) were retrieved. Analysis is carried out with the use of descriptive statistics. Findings from the study indicate a general lack of awareness of the concept of green designs and its certification. Users however appreciate the benefit of green features and majority of them are willing to pay for them if integrated in their buildings. The findings provide an encouragement for the expected green certification standards when introduced in the country and also trigger a need for intensive publicity of benefits of green buildings to stakeholders
