- [Queen Anne - Pelham Manor, NY](https://www.houzz.com/hznb/projects/queen-anne-pelham-manor-ny-pj-vj~6612943)
  - Location: Pelham Manor, NY
  - Photos: 21
  - Description: From old and stuffy to new, light and modern - the seeds of this iconic design existed in this old Queen Anne residence that had been neglected until the Mins purchased it. From there we transformed it into a modern living work of art that harkens back to the traditional detailing of the Victorian Age.
- [Modern - Gray House](https://www.houzz.com/hznb/projects/modern-gray-house-pj-vj~1747629)
  - Location: Not specified

  - Description: The building is tucked into the hill behind it and the long sweeping roofs reflect the linear creek at the front of the house as well as the boughs of tree branches cantilvering out over the yard 10’, engineered to do this without columns. The Veranda is the base around three sides of the house from which the design springs up from and it brings indoor living to the outdoor panoramic of the natural landscape. This also provides another 1,600 SF of space in the basement.
