     For many the idea of one day having your dream home is not buying a bigger home, but a home that

you have built by yourself. A house that is unique and fit for your tastes and your lifestyle. It sounds great

but where do you begin to design your dream home? Here is a quick guide that can help you make your

dreams come true.

     The first step is to get an idea of what type of home you want. You can get inspiration from others.

Drive around to neighborhoods that have the styles of homes that you like         and take pictures. You

can also cut out pictures from magazines, newspapers, or print-out pictures you find on the Internet.

     The next step will be to make two lists of items for yourself. The first list will be those items or features

that you feel your new home must have, such as granite (花岗岩 ) counter tops or a hot water heater.

The second list will be those items or features that are on your wish list like a fireplace or slate (石板)

floors.

     At this point you will probably have a good idea what your dream home will look like, so you will

need to seek some professional help. You will need to hire an architect to put your ideas down on paper. You may need to interview a few different architects to find one that you are comfortable with. Make

sure whomever you choose to make the final drawings has a full understanding of local building codes

 and zoning by-laws (地区议事程序).In any case your final plan will need to be approved by the city

and a building permit must be obtained before any construction can begin.

     It is time to look for a contractor (承包人). Whichever way you do it, be sure you are comfortable

with your contractor and you have gotten references from his past clients (客户). Remember the more

homework you do in the beginning, the more enjoyable the process will be.
