Step 1 Buy an old or new hallway table to fit over your air conditioner (we modified a Rekarne console table from IKEA for a perfect fit). Measure, then use a power saw along a clamped straightedge to cut decorative plastic panel to suit sides and front of table.
Step 2 Paint panels with spray-on plastic primer. Let dry. Prime table and let dry, then paint table and panels in 2–3 coats of Dulux Duramax in Vivid White. Let dry.
Step 3 Screw panels to table legs and rails through predrilled holes at an even spread of connection points to secure.
