The walkout basement can be used for a variety of purposes. Of the roughly 133 million houses in the United States, about 37 million have a basement, providing homeowners with more usable space. Many of these basements were left unfinished to be used as storage, extra bedrooms, or additional living areas in the future.
Homeowners who plan ahead by building their homes with an unfinished basement gain valuable living space at a lower cost compared to home additions.
Benefits and Challenges of a Walkout Basement
While a walkout basement adds space and value to a home, it comes with challenges. The two biggest drawbacks are the lack of natural light and limited outdoor access. The first issue can be solved with larger windows and window wells, while the second can be addressed by adding a walkout entrance.
Daylight basements feature open windows and doors to the outdoors, providing natural light. A walkout basement, however, has a direct exit to the outside through a dedicated doorway.
Creating a Walkout Basement Entryway
The easiest homes to convert into a walkout basement are those built on a slope, where one basement wall is exposed above ground. In these cases, creating an entryway involves cutting a doorway, installing a lintel, and adding a concrete pad. However, most homes require excavation work to build a proper entrance.
Drainage Considerations
Before installing a walkout basement entryway, proper drainage must be addressed. If excavation is needed, rainwater can accumulate in the stairwell, leading to basement flooding.
A French drain can be installed to help manage water flow. In colder climates or areas with heavy rainfall, a sump pump may be necessary to prevent flooding.
Adding a Roof Over the Stairwell
Building a roof over the walkout basement stairwell can help reduce water accumulation. A simple lean-to-style roof with corrugated metal or plastic can provide protection from rain.
Before digging, carefully lay out the stairwell to ensure it fits in the designated area. Some homeowners prefer a straight stairwell, while others opt for a 90-degree turn alongside the home’s foundation. A well-planned design minimizes trip hazards and improves functionality.
Choosing the Stairwell Material
Walkout basement stairwells can be made from poured concrete or cinder blocks. For DIY projects, cinder blocks are often easier and more cost-effective. However, concrete stairs provide a durable and seamless structure.
Installing the Door
A diamond-bladed saw is typically used to cut through the basement wall for the door. If the basement walls are made of concrete blocks, gaps in the cutout can be filled with construction adhesive and 2×4 sections.
A steel lintel must be installed above the door to support the wall above the opening. Once in place, the door frame can be attached using masonry anchors, and the door can be installed.
