The William Dyas Barn is a historic agricultural building located south of Bellevue, Iowa, United States.
 It is one of over 217 limestone structures in Jackson County from the mid-19th century, of which 58 are non-residential, agricultural related structures.
 The stones used to build the barn were quarried, but they vary widely in size and shape.
 The larger stones are at the bottom of the structure, and they diminish in size the higher up on the walls.
 An unusual feature on this barn is that the gable ends are not stone, but timber.
 The Dyas family were among the first settlers in Jackson County, arriving in 1833.
 They built five houses in this valley.
 William Dyas built a brick house along with this barn.
 It is believed there were many more stone barns in the county, but they have been removed over the years.
 That gives this barn the added significance of being an example of a vanishing building type.

The Howe Barn is a historic barn, that has been converted into a house, in Ipswich, Massachusetts, United States, at 421 Linebrook Road (403 before the street was renumbered).
 It is important as one of a small number of surviving First Period barn frames in Essex County.
 Family tradition places the construction of the barn to c. 1711 by Abraham Howe, an early settler of the Linebrook Road area.
 Elements of the frame, which are still visible in the attic and some areas left exposed during the 1948 conversion to a house, bear some resemblance to a similar period barn at the Stanley Lake House in nearby Topsfield.
George R. Cogar (born 1932) was the head of the UNIVAC 1004 electronic design team code named the "bumblebee project", and later the "barn project", and co-founder of Mohawk Data Sciences Corporation, a Herkimer, N. Y.-based multimillion-dollar business built largely on his invention of the Data Recorder magnetic tape encoder, which was introduced in 1965 and eliminated the need for keypunches and punched cards by direct encoding on tape.
 He also founded the Cogar Corporation, where he built an intelligent terminal—an early forerunner of the modern personal computer—which he called the Cogar System 4 or Cogar 4.
 The Cogar 4 became the Singer 1500 after Singer Business Machines acquired Cogar Corporation.
 In 1976 International Computers Limited (ICL) acquired Singer Business Machines, changing the name of the computer to the ICL 1500.

 The idealist Keith Collin and company wanted a sustainable, low cost, and environmentally friendly home.
 At least that was the Collin's plan,since 2006.
 So far there are only prototype BrightBuilt houses produced.
 Collin wants the beginning design to be a pathway towards implying more technological applications into common day houses, to bring better result for the environment, or at least that is his vision.
 From its inception, the design was driven by five guiding principles: livability, sustainability, replicability, disentanglement, and education.
 In the eyes of the designers this barn project is a stepping stone toward the future improvements that can start right now, especially since the barns Net Zero design can benefit the environments situation.
 The benefit could mean more energy is conserved in the years to come, which can help other small towns like Collin's.
