They are calling it the last major property for development on Monroe Center downtown Grand Rapids.

Rockford Construction today offered its first look inside the Morton House as crews work to turn the 91 year old building into apartments and retail space.

Rockford Construction's Mike Mraz tells WOOD Radio the building will eventually feature at least 100 apartments with various price points.

"There will be some areas that have fantastic views that will be prices accordingly. There will be other apartments priced a little less. We are still going thru that process.

The original Morton Hotel operated at the site on the corner of Monroe Center and Ionia in 1923. The building was turned into apartments in 1971 before closing in 2011. 

Rockford Construction purchased the building in 2011 and have been preparing the building for "market-rate" apartments. Mraz says the company will spend over $25 million dollars restoring the building, cleaning asbestos, installing new infrastructure.  

Workers have also discovered a few areas that haven't been seen in a long time.

"We found some ballrooms that were hidden away for a long time. We've uncovered some ornate detailing in some of the finishes and it was great to see the bank vault and the history behind it.

Rockford Construction expects to begin leasing apartments this summer with the first tennants to move in next year.
