Sandra Leigh Lester advises architects about ways of making buildings more sustainable, healthful, and beneficial for the wider community. Claire Adamson is a retired architect in Montreal. They both have issues with the fashionable ways of renovating homes. Adamson dislikes the trend toward "open kitchens." Lester says some of her clients want granite countertops and other things they don't need; they should pay more attention to such things as valves to keep sewage from backing up into their basements.
