Two things were done

Replacement in kind of interior wall coverings. Replacement in kind, when applied to architectural features, means replacement with a feature of like material that replicates the existing feature in proportion, appearance, texture, design, detail and dimensions

Replacement in kind of up to 5 fire windows. Replacement in kind, when applied to architectural features, means replacement with a feature of like material that replicates the existing feature in proportion, appearance, texture, design, detail and dimensions.

Did he hide something in the walls? Soundproof the windows?

Stranger yet, he does not own the property https://www.taxpayerservicecenter.com/RP_Detail.jsp?ssl=2833%20%20%20%200099

The owner is Boris Rochilin, who ever that is.

Some of the records that a company called CASTELLUM ACHILLES asked for permits. http://otr.cfo.dc.gov/sites/default/files/dc/sites/dcra/publication/attachments/201501Building_Permit_Issued_Jan_2015.pdf

When you look for this company you find information about a company called CHRISTOPHER ACHILLES LLC . https://opencorporates.com/companies/us_dc/EXTUID_2878514 Owned by JAMES ALEFANTIS, ! His lawyer, ROBERT A. HARRIS IV has opened many LLC with Alefantis.

The house don't look like a place a rich, well connected person like James Alefantis would live: http://www.zillow.com/homedetails/3518-11th-St-NW-Washington-DC-20010/472684_zpid/

Why would James Alefantis (a chef and restaurateur) use an LLC to do home renovations on a house he doesn't even own?
