Antique doorknobs with BB initials - B Brothers! If there is a good spot in the boys' room for this - adorable!
two matching "entry size" early 20th century heavy cast yellow brass baskin brother jewel store doorknobs with centrally located monogrammed design - Vintage Builders' Hardware - Doors & Hardware - Products
Built-in Fire Escape ladder. Should really have in all second floor bedrooms, but STRONG feelings about having in boys' bedrooms. Installing while building - hopefully can make more discreet. Perhaps a simple push latch on a drywall "door." Or if there is wainscoting, easy to make a molding square conceal the door.
