What is Arcalus?

Arcalus [AR-kuh-lus] is a period design consulting resource like no other - a companion for old-house owners, architects, designers, writers, researchers, and preservation groups involved in projects where a meaningful connection to the past has high value.

Arcalus is also a period design archive and private library built around the Rejuvenation Collection, comprising nearly 2,000 original trade catalogs, home guides, plan books, sales samples, and other vintage primary source materials documenting the American building arts from 1870 to 1970.

Arcalus founder and owner Bo Sullivan offers hourly design consulting as well as a number of accessible fixed-price packages to help old-house owners get the most out of projects on a limited budget. Services include architectural authenticity and integrity assessments, house history research, period color documentation, suggestions for date-specific design and product solutions, and custom-created “look books” of original interior images drawn from old books and catalogs to inspire fresh ideas today.
