A home office becomes a cozy place to work in or a great place for kids to their home work if done up the right way.
Incase your home office is a large enough room start by clearing out all possessions and plan a place for all office units and your work table. Consider all lighting options and make allowances for the same. Paint the walls a soothing shade and select curtains and furnishings to match or coordinate.
Continue the color scheme on paintings, wall art or other décor elements to unite all aspects. If the room is a part of another room make sure all décor synchronizes with existing room décor.
Add a cozy rug; throw cushions and photographs of children to add a homely feel to the room. You could even add personal touches to the storage cabinets and units to get a well worn and comfortable look.
