Other important characteristics of residential interiors include the other professional instructions and education programs a designer must be thorough in understanding. Construction and skilled-trade jobs, including brick masonry and carpentry, are examples of some of these characteristics a designer should learn. Others professions where at least an association should be established include plumbing and electronic trades.

The residential designer would be greatly recommended to form a professional relationship with several real estate agencies and brokerages in his or her area. An exchange of information, both financial and professional, would result in the agent's elevated understanding of idea and cost possibilities for the homes they are selling. The interior designer would be able to generate business through referrals from the agent.

Each specialty and subspecialty of residential design would require a different professional focus. The designer specialized in bed and bathroom plans should of course have a thorough knowledge of plumbing needs, but should also spend as much time as possible learning space and organizational design to assist a client in making the most of whatever space his or her home has compared to his or her furniture and storage needs.

The residential interior designer is best served by providing excellent customer service and communication. Most of his or her clients will not have an understanding of the difference between an interior decorator and an interior designer. But by taking the time to soothe homeowner concerns over cost and design appearance, a lasting business relationship could be developed and referrals could become quite common.

That attitude spells financial and professional success for any small business, but it most certainly equals success for the any interior designer.
