Maintaining a functional office space can be costly. The overhead expenses associated with an office can easily overwhelm a small business. If you are finding the costs of running your office are too great, there are some ways to make your office space more financially lucrative.

Here are three office rentals options that you can make your office space more profitable in the future.

1. Rent out meeting rooms after hours.

If your office building features good-sized conference rooms, you can generate some profit by renting these rooms out after your business has closed for the day.

Many entrepreneurs working out of their homes need professional locations to meet with clients or investors on an occasional basis. Offering your company's conference rooms to these entrepreneurs can be a great way to allow your office space to generate profit in the future.

2. Partner with an independent yoga instructor.

The health and wellness benefits associated with yoga have made this form of exercise popular among the masses. Since participating in a yoga class requires access to no specialized equipment (only portable yoga mats), you can easily partner with an independent yoga instructor to transform your office's large meeting room into a lesson space after business hours.

The instructor will be glad to have an intimate and quiet space in which to conduct group sessions, and you will be able to generate some additional income by charging for access to your meeting room in the future.

3. Find another company to share office space with.

If you really want to reduce the cost of your overhead expenses, you can partner with a company whose business hours don't conflict with your own.

Finding a company whose employees work during the night in order to accommodate a foreign clientele allows you to share office space without compromising your own access to amenities. Both companies can share the overhead costs of maintaining an office space, making it more affordable for both you and the company you opt to partner with to operate in a nice office space in the future.

Finding simple ways to reduce your overhead expenses can make your company more profitable. By renting out your conference rooms to entrepreneurs or private yoga instructors or partnering with a company whose business hours don't overlap your own, you will be able to generate additional income that can offset the overhead costs associated with maintaining a private office space.
