Highline
Our Story
Mile High Designs was formed in 2005 as a small two man subcontracting crew. With a lot of hard work, we’ve grown into a highly rated family business with a team of valued employees and trade partners ready to transform homes throughout the Denver metro area and mountain communities along Hwy 285 and I-70.
In 2019, after a few cases of mistaken identity and a lot of consideration, we started transitioning to doing business as Highline. There are so many ‘Mile High’ service companies out there and we don’t want to be mistaken for other less than stellar competitors.
But don’t worry, Highline is still delivering the same award winning service that made Mile High Designs thrive. Contact us today and let us know how we can help you.

Our clients love us but we love them more.
