Three-year-old Sean Kearns has bilateral perisylvian polymicrogyria (BPP), a condition which means he uses a wheelchair and needs a permanent feeding tube.
He also has epilepsy and cerebral palsy and will require 24- hour care for the rest of his life.
The youngster was withdrawn and unhappy in the family's previous home - a traditional two-storey house, not suitable for someone with a disability.
But since they moved into their new house in Moodiesburn, North Lanarkshire, the family has noticed a huge difference in the youngster, who lives with dad Paul, 34, mum Nicola Devlin, 31, and brothers Rhys, 13, and Evan, 5.
Nicola said: "In the previous house, we couldn't get Sean's wheelchair around the house and he wasn't able to go where he wanted.
"He was basically stuck in his room with just the same four walls to look at and he would get upset.
"But the new place has made a massive difference.
"He can get around the whole house and be a part of things, which has brought him out of his shell.
"Doctors said he would never talk but since we moved in he's started saying 'hiya' to everyone and he won't stop!
"We've been here a few weeks and we've seen a different side to Sean."
The three-bedroom bungalow off Gartferry Road has lowered sinks and light switches and a host of other adaptations to make life as easy as possible for Sean.
It's part of a development of 50 new family homes built by North Lanarkshire Council as part of a £150million plan to put up 1000 new homes by 2020.
The site, built at a cost of £5.6m, contains 50 properties which are a mix of semi- detached homes, bungalows and four in a block flats.
The Scottish Government provided grant funding of £1.25m for the project.
All the properties are energy efficient and accessible and are designed to be easily adaptable for tenants with disabilities.
Councillor Sam Love, convener of Housing and Social Work Services, said: "The most important thing is these homes are about people, and the lives they can build in them."
l Bilateral perisylvian polymicrogyria (BPP) is a rare neurological disorder that may be apparent at birth, infancy, or later during childhood.
It is characterized mainly by partial paralysis of muscles on both sides of the face, tongue, jaws, and throat; difficulties in speaking, chewing, and swallowing; and/or seizures (epilepsy).
It's thought to be due to improper development of the outer surface of the brain during the growth of the embryo.
