Do I need the Merchant's Row I building kit to use this?
Yes — this Spaces insert is designed to fit inside Walthers Cornerstone Merchant's Row I (#933-3028), which is sold separately.
How are the LEDs powered?
The LEDs are low-voltage and designed to be powered by a standard layout DC supply or DCC accessory bus. Wiring is straightforward and detailed in the included instructions.
How much assembly is required?
Very little. The interior sheets are pre-printed and the LEDs come ready to mount, so most modelers can install everything in an evening without painting or weathering.
Will the interior detail be visible from outside the building?
Yes — the printed scenes and 3-D tool details are designed to be seen through the windows and doors of the Merchant's Row I structure, giving the storefronts a much more lived-in look.
