  • 1.  Rehabilitation projects with CNC-manufactured elements?

    Posted 03-31-2021 01:17 PM

    I am searching for examples of rehabilitation projects that have used CNC-manufactured elements (preferably wood) to provide aesthetic contrasts with historic fabric and/or for functional purposes. I am advising a Masters of Architecture student who is developing plans for several small early twentieth-century buildings in a rural community in south-central Kentucky. He envisions using CNC structural and decorative elements to expedite construction and create distinctive, inspiring spaces. Obviously, these projects would not be required to meet the Secretary of the Interior's Standards or be subject to local design review. The intent is to do something creative and interesting that blends old and new.

    I have searched for firms that are doing this sort of work and for projects that might offer useful examples. So far, I have not found much. Most people who are using CNC elements in rehabilitation seem to be doing replication of historical features that have been lost or become severely deteriorated.

    Can any of you suggest projects I should look at? Or designers who are working in this mode? Any recommendations would be greatly appreciated.

    I've talked to more than one supplier of historic-design or traditionally inspired hardware who use CNC to produce parts such as knobs that historically would have been cast, forged, or produced in some other traditional manner -- even 19th century proprietary processes. E.R. Butler I believe is one; their designs are excellent.

    Contact Jim Crone of the Burklyn Inn located in Vermont.  
    As owner and contractor, he has invested almost 2 years in rehabilitating this turn-of-the-century private residence into a functioning inn.   He has replicated many trim elements on the facility.  Some of those reproductions may have been produced with CNC process.   You will need to check with him directly.
    I have provided him with architectural support in resolving only exiting, fire rating and disabled access issues.
