Many people ask me about basements and are they good spaces to store stuff or make as a home office. I say YES! But here are a few things to consider before you do.
Any space below ground level are more prone to dampness, poor lighting, poor ventilation,and bugs and other creatures. Make sure its a secured space. Check the walls and floors. Is it fully covered. If there is a window down there, can it be securely closed. Also can it be opened for air. Maybe a screen over it will help with anything flying or crawling in.
If you can put a heating/AC system in there, I say do it! The bottom line is you want great ventilation down there. Your house and your stuff will thank you!
Make sure its well-lit. You may have to bring lights/lamps down there. Make sure all electrical outlets can handle all the plug-ins. An electrician has a device that can scan and tell you. Sometimes the basement houses the washer and dryer or an additional freezer/fridge, you want to make sure all circuits can handle any additional things you plug-in down there.
Also check that the steps leading down are secure, with something to hold onto going up and down!
