The client is a builder who wishes to target the first-home owner market. First-home owners or buyers are normally young families with children, with limited budget that cannot afford expensive homes.
The dominant theme for the logo should be as follows:
The logo should communicate the notion of a builder who cares about young families, their lifestyle and budget by emphasizing energy-friendly solutions.
The overriding colors for the logo could be a combination of greens and blues or purple.
I envisage the logo to include both a symbol and text. Note that because of confidentiality issues, the slogan will be known only to the selected supplier.
