If this renovation is to be considered a success, its due in large part to the work of the project team to address building system and maintenance issues in addition to aesthetic issues. Though the new finishes increased the value of the house, without a holistic approach, the finishes would not have been worthwhile: the mold issue would still be a concern, the lighting wouldn't be sufficient, etc. Your Architect can work with you to develop design solutions that balance the issues of your project and make the most of your investment.
