The Refinery is where you produce Refinery Salts, which are used throughout construction, as well as in crafting recipes and alchemy.
Salts are needed to construct/upgrade buildings among other things. The refinery will start converting resources into salts.
Go to the refinery and turn on the first tier. Some spaces can take longer to unlock than others explore which ones are cheaper before settling for the location. In time these will unlock more spaces for you to place cogs or characters. Toggle "Place flags" ON, then click on locked spaces to place them. Placing characters on the Cog Shelf will add the characters' production value towards making Cogs, and award the character the same amount of experience as if they were placed on the board. Adding your characters to the Cog Board is the only way to increase Build Rate before acquiring Cogs, and the primary way to acquire character experience in Construction. Construction on a building isn't complete until the material cost has been paid. Once the "Build" phase is complete, you can complete construction with a material cost. SUPER PLAYER OMNI BOARD FULL
If you queue up multiple buildings at once, they all get your full Build Rate.
In order to construct a building, it must first go through the "Build" phase where the progress bar fills up according to your Build Rate. Inside this table you can construct buildings or access your cog board. In world 3, Construction is available from the wooden table (pictured on the left).
