If you're dealing with a sloping lot, don't panic. Yes, it can be tricky to build on, but if you choose a house plan with walkout basement, a hillside lot can become an amenity. Walkout basement house plans maximize living space and create cool indoor/outdoor flow on the home's lower level. If you're building a vacation getaway retreat or primary residence in a scenic area, like the mountains, or by a lake, the more indoor/outdoor living space the better. Moreover, if you enjoy entertaining guests, a walkout basement house plan might be even more perfect for you. Why? Because walkout basements often boast rec rooms with adjacent patios. Just imagine BBQ-ing on the patio while guests play games or watch sports in the rec space. This is a practical way of throwing a party, as it allows the chefs to stay in communication with the rest of the group. Walkout basements also often hold extra bedrooms that can be used if guests typically spend the night. That said, extra bedrooms can also be used for other activities, like a hobby workshop, workout room, or secluded library. Note: if you're building a walkout basement in a cold climate, consider building your foundation with insulated concrete forms (ICFs).
