If possible, a design-build firm may be the most efficient option for building a custom green home. A company can offer both an architect, and builders to work together on a new custom home. A green architect working for a firm is more likely to create plans, that they know from experience, will be easy for the builders to complete.
The only problem is, it can be difficult to locate a local firm of this nature. Resources, such as the Green Home Guide, offer green design-build firm listings, as well as helpful information. Also, if using a small firm with a limited number of designers, ensure they will be able to give your project adequate attention.
Do your part to give your custom green home the care it deserves; educate yourself on eco construction, and fully investigate potential green architects and builders. In the end, your house will be the sustainable, energy-efficient home that you had always dreamed of.
