At the Museum of London end of Mountjoy House are two very similar penthouses, side by side, on the top floor - one is the only Type 33 and the other is the only Type 34. The Type 34 penthouse has a living room which takes advantage of the side and end wall of windows (on the church side). Further back, there's a single bedroom. In addition, there's a roof patio. It is slightly larger than the Type 33; it has an additional bit of hall outside the bathroom.
