Explore Custom Home Construction →The right plan depends on your existing home, available space and goals. For an addition or guest home, we review access, drainage, utilities and the proposed layout.
Soil and foundation needs can also affect the work. We coordinate engineering reviews when needed and use the findings to guide construction.
For an attic conversion, we review the structure, ceiling height, stair access, insulation and heating and cooling needs.
A Missouri City mailing address does not always mean a property is inside city limits. We confirm the location and the agencies responsible for the proposed work before construction.
Within Missouri City, new homes, additions and many remodels require permits and inspections. Depending on the work, this may include building, electrical, plumbing and heating and cooling permits, along with energy-code review.
For properties outside city limits, Fort Bend County or Harris County requirements may apply. Drainage, floodplain, septic and utility approvals may also need review.
HOA approval is a separate step. We review the design rules and prepare a package for you to submit. If your HOA needs renderings, we discuss the design options with you first.
This 1,000-square-foot mother-in-law home includes a kitchen and living area, a primary suite, laundry, a guest bathroom and a covered front porch.
After an earlier HOA rejection, we revised the design and prepared the approved submission. We then coordinated city permits, inspections, three feet of soil replacement and utility connections, including a separate electric meter with lines running about 180 feet.
The 11-month build used zero-VOC paint, floating floors installed without glue, wood cabinets and granite counters.
