You might call it the old hotel on the hill.The old Marriott hotel at Hampden Avenue at Interstate 25 is being torn down to make way for a new development. The main building, the one that can be seen from I-25, was built in 1973 and opened a year later.This was the edge of town at the time it was built. As the Denver Tech Center was developed, there is a lot of office space down there and the center for the business for the hotels has moved south but this hotel was doing quite well, said David White co-owner of the property.The other wings of the hotel were constructed and opened in 1978. The 12-acre site and home to Denvers eighth-largest hotel with 615 rooms started as a Marriott but became a Four Points Sheraton five years ago. When the lease expired at the end of 2008, Sheraton decided not to renew so the property reverted back to the original owners, the Geiser and White families, at the end of 2009.Its kind of a mixed bag. This was built when I was in high school and so it goes back a ways. Its part of our life, essentially a family member. We hate to see it go on the one hand, but when we first bought it this was an airport and before then it was agricultural ground, so time goes on. We need to redevelop and change the use, said White.The new development will be called Highpointe at Hampden and according to their Web site will consist of Mixed Use Development: Multi-Family / Senior Housing / Hotel / Retail / Commercial.Im not able to go into any specifics but were looking at probably mixed used retail redevelopment. There will be some retail stores, maybe some multi family. Hard to say depending on what the ultimate build out looks like, said White.The hotel has served as a very important part of the southeast Denver community, Robert Gaiser, co-owner of the property, said in a statement. As the Denver suburban hotel market moves farther south and/or towards Denver International Airport, the time has come to rethink the use of the building and this prime location, Gaiser said.Jim Gochis, the co-owner of Alpine Demolition said the demolition will take four to five months to complete.Its a high building and its in close proximity to residential so we have to take some care there. A lot of big structures are built the same way. If you take the façade off them or you take the insides out of them they are basically a building thats got a lot of energy stored up top and you have to take it down in a very controlled fashion.The old buildings were constructed with asbestos so special care and cleanup needs to be completed first before the structure can be taken down.Were working with a company doing the asbestos abatement and as they clear one building we can go take that wing down, said Gochis. Most of this building, 85 to 90 percent well take to another facility to be recycled. All the steel and aggregate will be reused.White says what gets to him the most while watching the demolition are all the memories that were made in the old hotel and all the history that is coming down.Its been a real important part of our life. Weve been very glued to it as a family. We had a wonderful relationship with Marriott and with Four Points for the years that they operated it. Its been a great community center. Thousands and thousands and thousands of meetings and bar mitzvahs, weddings. Just all kinds of things that have gone on here so it was an important part of the community and our intent is to redevelop it and make it a part of the neighborhood.To see a schedule of the demolition and to get updates on the new development visit the website, Highpointe at Hampden.
