Eric Lansdown would gladly build more in the direction of this style. This series of four tower chateau were about 7 feet tall with dormers at about eye level for an adult. The facade and towers open separately.
A base price includes a similar level of finish as seen in the photograph. Additional details such as opening mullioned windows and of course attention to the interior can be discussed. If the piece is destined to become a dolls home it would normally become a very long term project just as a real chateau. Interior structure can be designed for successive decorative upgrades.

Base price 6000 euro
