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.
The building site also needs to be taken into consideration for school districts, noise levels, and neighbours. Different sites will also require different types of permits at different prices. Planning a new home can be challenging as it is a big investment, so the new home should meet all of your specifications. Depending on what stage of life you are at may also indicate the style of design you need to consider.
For example, in the southern United States sunshades and louvers as well as light colored building materials for roofing and cladding help to reduce the heat gain. Sustainable design also means that every inhabitant has access to outside views with natural light and natural ventilation. This sometimes results in narrower floor plans, or articulated plans which expose interior areas to several exposures. The contemporary house plan is designed with the goal of reducing fossil fuel consumption, and providing a healthier and relaxing environment.
