A switchback, often known as a "U"-shaped staircase, may be the ideal option for you. A switchback staircase is simply a staircase with at least two flights of stairs facing 180 degrees from each other with a landing platform in between. At the top of both sets of stairs, there is a single door which leads into your home. The bottom of both sets of stairs also has a single door which leads out to the driveway or sidewalk. By alternating which stair you stand on, you can go up one flight and down the next, always staying on the landings, where there are no steps or risers to trip over. The advantage of a switchback staircase is that it requires less space than a conventional staircase, which can be useful if you don't have much room for a new addition. It can be built inside or outside your home, depending on your preference. And since it's not as wide as a traditional staircase, it can be moved easily if you want to change its location within your home. Finally, a switchback staircase does not block traffic flow while you're walking up or down their stairs, so they are perfect for people with physical limitations who need to be able to get upstairs or downstairs without first moving all their luggage or appliances. These are just some of the many advantages of a switchback staircase.
