Wheelchair accessible home for Bell

Bellamy Arterburn is a very bright, funny and kind 18-year-old girl, and so are her twin 16-year-old sisters Savannah and Skylar. The girls all share a genetic condition called Friedreich's ataxia (FA) - a debilitating, life-shortening, degenerative neuro-muscular disorder. About 1 in 50,000 people in the U.S have FA - there is currently no cure. The typical symptoms are loss of coordination (ataxia) and muscles, fatigue, aggressive scoliosis, and a heart condition (cardiomyopathy). 
My name is Halle Nagorsky, I am 17 years-old and live in Philadelphia, PA. Bellamy and I met 2 years ago and have been best friends ever since. I visited their small apartment in Denver, CO this past March. It broke my heart to see that there wasn't enough room for Bellamy and Savannah to use their wheelchairs inside; let alone that the only way of getting to their front door is a flight of stairs. The girls get carried around, typically on their father's back, to get inside the apartment, go to the bathroom, or go to their bedroom. They spend most of the time on their family room couch, and if no one is around to carry them then they are stuck there.
Bellamy and her sisters were diagnosed with FA in 2008 when they were 10 and 8 years old respectively. Shortly after their diagnosis, their mother passed away from breast cancer. They always made things work, but now all three of the girls require a wheelchair.
Bellamy loves learning and music and attends as many concerts as she can. She is currently taking a few online college classes from home because she is too weak and tired to go to classes at the nearby college. She is constantly in extreme pain due to her heart condition (cardiomyopathy). 

I have never met anyone as strong as the Arterburn girls. They have had to endure countless back surgeries and many medical tests throughout their life to best treat some of the FA symptoms they have. However, this isn't  the only thing that makes them strong - it is their unwavering bravery, resilience and positive outlook on life that makes them the amazing people that they are. Their current house is too small for the number of people living there, and the wheelchairs can not move around inside. Moving to a house with ramps, an accessible bathroom and space for the girls - enabling them to be more independent, would truly be life changing. Please help me make this a reality for them by donating whatever you can!
