Second-generation space, a new shell, or your own building?
The choice depends on how far along the corridor you are leasing on. Along the retail and service strips that have grown up around Sienna and the other master-planned sections, most of what is available is either a grey shell that has never been finished or a second-generation space a previous tenant left behind. A grey shell gives you clean slab, open ceiling, and stubbed utilities, which means the layout is yours but every wall and every duct is new cost. A second-generation space carries walls, restrooms, and HVAC you may be able to keep, and the buildout becomes an exercise in what to reuse and what to demolish.
Ground-up is the third path, and in Missouri City it usually means a small freestanding building on an outparcel or a pad site in front of a larger center. It gives you control of the building envelope, the parking layout, and the signage, and it adds site work, utilities to the street, and a longer approval path to the schedule. We walk all three options with a client before a lease is signed when we can, because a lease negotiated around the wrong assumptions about the space is the most expensive mistake in commercial construction.
