We like building houses, pina coladas, and long walks on the beach. Besides that, we’re a local, privately-owned group of builders, designers and project managers that strive to create some of the most unique homes in Denver’s favorite neighborhoods. Our “mountain meets modern” aesthetic blends the best of urban living, modern style and Colorado character. 


Since 1999, we’ve built personalized homes that have brought our upscale design and quality philosophies within reach for many homeowners across the Denver Metro area. Michael Griger started MAG Builders in Vail, Colorado as a custom framing contractor known for superior construction. In 2002, this growing company moved to Denver to realize the company's calling of design-to-build custom homes. 


Where to start? Besides building a collection of unique floorplans for our customers to personalize to their heart’s content; our process is 100% customer-friendly, personal and hassle-free; and we have superior sustainable practices that keeps Colorado beautiful. Plus Mike is super good at Foosball. From start to finish, we’re a different kind of builder, because you deserve a truly unique home and homebuilding experience. To learn more, check out our process a little more in-depth. 


Whether you want a home design that’s ready to go or want to add your personal touch to make a floorplan fit your life, we’ve got your back. Our in-house architect is there to make layout and design tweaks. We’re a Starmark Cabinet dealer, giving you the power to make design and style changes. We also use Pro Kitchen software to help make everything easy, fast and smart. Basically, you’re the boss, and we’re the builders.

We’re big fans of Colorado living—from mountain adventures to the Mile High City, the Big CO was recently voted the best place on the planet by us. That’s why we love building homes in some of the city’s favorite neighborhoods like Berkeley, Highlands, LoHi, Cory Merrill and DU. Let’s be neighbors.


We provide full project pricing contract for the entire project at the time of authorization.  No need for home construction loans or complicated and risky financing, MAG has you covered.

The skinny:

Most construction loans require 20–35% down that require costly inspection fees, appraisal fees, monthly interest payments and origination fees. On top of that, construction loans slow down the build time with bank inspections and waiting for them to cut a check, which is a bummer. At MAG, we do things differently. All you need to do is put two separate 10% deposits at Canyon Title. That deposit then sits in an escrow account and is used towards the deposit on your permanent financing, not held in a MAG account. The first 10% is due when we get a successful contract and the second 10% is due after framing is complete. Then, get the chips and dips ready for the housewarming, because you’re only two months from moving into your new MAG home.


We do that under-promise and over-deliver thing that people seem to love with build times that rank among the quickest in Denver. From excavation to getting the final Certificate Of Occupancy, it takes us just three months on average. Most builders take 6-12 months to complete their homes. “BUT HOW?!?” you ask. It’s simple, Watson: MAG is self-financed. No construction loan process or waiting for bank appraisals to cut checks. We pay all our employees and contractors weekly not 30-60 days like other builders. Also, with our in-house staff, we can handle situations that need immediate attention that other builders need to wait for their contractors’ schedules to open up. It’s just how we roll. 


Like you, we think Colorado is pretty awesome and we want to keep it that way.  So we use super efficient building design, tank-less water heaters, high efficiency furnaces, recycled teak deck tiles, recycled steel reinforced framing, recycled steel roofing, LED lighting, smart home automation, Energy Star appliances, water efficient fixtures, low VOC materials, and we're a member of the U.S. Green Building Council. Oh, and we donate any excess materials to Habitat for Humanity's local projects. You’re welcome, Nature. 


We like building houses, drinking pina coladas and long walks on the beach. Besides that, we’re a local, privately-owned shop that specializes in making unique homes. We’re not a faceless mega that reports to stockholders—We’re privately-owned company by two friends (coincidently both named Mike) that report to you. Our passion is to make our neighborhoods better by building homes that are better quality, better for the environment, and an better building experience start to finish. We’re a local team of expert builders, architects, and interior designers that love Colorado for its natural beauty and outdoor lifestyle.
