How to Build an L-Shape Kitchen Island

An L-shaped island creates extra work space in your kitchen.

A kitchen island allows you to access the area from all sides and provides extra storage and work space. An L-shaped island is even more practical and offers convenience. It's not difficult to add an L-shaped island to a new or existing kitchen if there is adequate space.

Things You'll Need

• Chalk line
• Measuring tape
• Cabinet or base material
• Countertop material
• Hand tools
• Construction Adhesive
• Small finish nails
• 2 x 4 x 8 inch wooden strips

Instructions

1. Draw a chalk line on the floor to get a feel for spacing and determine if you need to rearrange or change angles for the L-shape (Reference 1).

2. Take measurements for the island. Allow 36 to 42 inches between cabinets and the island if it is near a plain wall and at least 36 inches if near an appliance. An allowance of 42 inches is best (Reference 1). Assure the L-shape gives adequate pass-thru space and meets other recommended allowances.

3. Analyze the purpose of your island and plan accordingly with the placement of sinks, cabinets, appliances, bookshelves, wine racks, snack bars and other options (Reference 1).

4. Decide on the desired height of your island, which is normally the same height as the rest of your kitchen counters. If you plan on having a snack bar with bar stools or differing levels of countertop space, measure accordingly.

5. Determine base materials and countertop choices for the island. To create the desired L-shaped island, two or three base cabinets will likely be needed. Decide if you will do the work yourself or hire it out. Consider the required skills and tools for the job.

6. Measure the inside perimeter of the base of the cabinet(s). Mark those measurements on the floor. Place 2 x 4 x 8 inch long wooden strips (also known as cleats) on the inside of the measurements on the floor (Reference 2). Use a wooden strip for the inside front, back and both ends for each cabinet used for secure attachment of island (Reference 2). Use appropriate nails or screws, depending on the type of floor, to secure the wooden cleats (Reference 2). Apply adhesive to the outside edge of the cleats. Set the cabinet over the wooden cleats and use small finish nails to secure the cabinet to the cleats. Attach the toe kick in the appropriate place using construction adhesive and small finish nails (Reference 2). Attach your choice of countertop securely.

Tips & Warnings

• Consider other options if space does not allow for an island by using a portable utility cart or a single cabinet and add a butcher block or ready-made countertop to it. A straight line island may allow more walk space than an L-shaped one.
