Mark's first design project for me was in 2003 on one of my vacant parcel building sites on Quail Tail Trail in Sedona, AZ. I also hired Mark to design two more homes for two other vacant land parcel of mine also located on Quail Tail Trail in Sedona, AZ. > > Mark's house design for the three projects gave potential buyers the vision needed to conceive what was possible to build on the two narrow long lots and one small triangle lot and still take advantage of the Sedona Red Rock vistas and the local zoning building setbacks. The two narrow lots sold and enabled me to pursue other vacant land opportunities in the mountains of Boulder, CO. > > I also engaged Mark to do a preliminary house design for the 20-acre parcel I purchased in the foothills of Boulder, CO. His design enabled me to receive preliminary approval for a 4,800-foot house from Boulder County. > > Currently, Mark and I are reviewing the need for a potential design for the one final vacant lot on Quail Tail Trail, that does not have a Mark Farrar house design attached to it, for the potential buyers to envision the possibilities. > > In closing, Mark Farrar is patient, methodical and a good listener who will help you transform your vision into the house design that meets your needs and the needs of the building site to be transformed into a homesite. **★★★★★ — G.W. WILE, Aug. 2019** > Mark Farrar is the Designer that's helped me put My Ideas into reality for better than 20+ years. I highly recommend his services... and once he's worked with you... you'll be recommending him to others well. This may sound a bit quaint, but Mark really is one of the good guys. > > GW ## Selected projects - [Farrar Residence](https://www.houzz.com/hznb/projects/farrar-residence-pj-vj~5705516) - Location: Bozeman, MT - Photos: 5 - [Witte Log Home](https://www.houzz.com/hznb/projects/witte-log-home-pj-vj~5682656) - Location: Bozeman, MT - Photos: 28 - Description: Some people just want the authentic log home. The logs used here were hand-hewn, not uniform; but fitted together and chinked. Faux stone was used to save a little money, but when the skirting around the deck was added, this was no longer evident. Structural trusses were also made from solid logs and sized and graded to leverage the spans they supported. Windows surrounded the vaulted Great Room to allow natural light to flood in and a clawfoot tub set the stage in the bathroom.
