It is wise to speak to your architect about potential roadblocks in the project and about any other extras that are likely to be added to your bottom line figure. You may also want to discuss anything that your architect may think is a better design choice.
The challenge for the designer today is to produce ecologically-sound buildings without compromising contemporary concepts of beauty. There are plenty of examples of excellence in sustainable design which is soundly built, well-fit for its purpose, and an aesthetic delight. Even small luxury home plans are increasingly ecology-conscious in their choice of materials for conservation of resources and self-sufficiency.
Ranch style architecture originated in the United States in the 1920's, and it became very popular after World War II as cities expanded into suburbs and inexpensive tract homes were needed by a growing populace. Ranch style houses are most popular where land is inexpensive and the weather is mild, since these homes particularly lend themselves to outdoor living. The low, earth hugging look with clean, modern lines of the ranch style is derived from Frank Lloyd Wright's prairie style architecture.
This style of architecture became quite popular in the United States between the 1890's and 1940's. Interiors, because they are small, can give a cluttered but utterly functional appearance, with artistic niches and nooks, and knick-knick decor. Cottages are designed for a relaxed, simple lifestyle - places to come home to, kick off your shoes, and flop on the furniture. They are not designed to impress other people, but to make their owners feel good. Cottage living often involves gardening, and most cottage owners spend their weekends and vacations outside in their backyards, digging in the dirt and growing flowers and vegetables.
