Sample and data collection
The data for this study were obtained from building owners who had procured the services of architects in designing and constructing their buildings. For this purpose, estates in different locations in Lagos, Nigeria were purposefully selected. Lagos is a place that is considered the commercial centre of Nigeria and the rate of urbanisation in the state is higher than that of other states. Similarly, the level of construction projects in the state is also higher than in other states. The sample consisted of building owners in the selected estates. The first task for the researchers was to locate these building owners, and then ascertain if they sought for architectural consultancy in their building projects. Once this was confirmed, the respondents were asked to fill the questionnaire. The data collected were analysed using SPSS version 21. Data were analysed using descriptive and statistical tools, some of which can be seen in [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24].

Implications of study

The data serve as a standard to ascertain the level of satisfaction of clients of architects. It will also serve as a basis for further studies in other locations. The data suggest areas that clients are not so satisfied with their architect and the key factors to be addressed to client satisfaction.
