After realizing that the Art Deco in the office is no longer acceptable the next best thing is to redecorate. So, calling a design team no longer comes across as something that's not wanted. It's hard to choose between design styles. The directive has been given to the design team that they have the freedom to work within established decorative parameters and budget. It's a good plan to have and better that an efficient team has been selected to fill the need.
Just think of future business partners and deals that could happen at the office. It would be nice if the décor weren't too old or out of place. An analysis of future and present business partners could reveal that something way more contemporary could solve the problem. Don't be discouraged if the look that's wanted is not the best for the company. The key is to find something that suits the office persona and the deals won't stop coming.
Sometimes an office is most appealing if it goes back to the basics. Maybe a sofa, chair, and table in the main waiting room will seal the deal. Or trying a desk with random magazines strewn across it will suit the offices' style. There are multiple combinations that can occur with the furniture and accessories with the rooms of the office. Don't stress over the issue because this will solve itself regardless as to whether the budget for a design team has run low or there is an internal lack of interest.
Over all, simple is always best. High Renaissance may be eye catching, but it in no way is part of the simple. Complex works are usually not in line with the goals of the organizations' mission so don't worry if your choice for designs didn't get accepted. The progression of the firm is, for all intents and purposes, the most important thing to consider. Moving back to basics will help the business maintain and stay the course in the effort to procure clients and create profits.
