Marina, Thank you for contacting Cynthia J. Hoffman Interior Design, Inc.! The wood siding for this Ohio project was charred on site, 3 boards at a time. Altho it is impervious to insect damage and never needs painted or stained, it is not suitable for flooring. Instead you could use a highly figured wood for your floor and have it stained charcoal letting the grain show thru to get a similar look. Please let me know if you have further questions. Good luck with your project! Thank you. Cynthia
