Wells and septic
Many Magnolia homesites rely on private water wells and on-site septic systems. We coordinate the system design and county permitting early, because they affect where the home can sit.

Local Expertise
Magnolia is a favorite for families who want acreage, privacy and room for a barndominium-style shop or pool — while staying close to The Woodlands and Tomball. We build custom estate homes on wooded and open lots throughout the Magnolia area, about 25 miles from our Willis office.
An addition is often the best way to gain space without giving up a location you love. The challenge is making new construction blend seamlessly with the old — matching brick or siding, roof pitch, ceiling heights and trim.

Typically 3–6 months of construction depending on size and complexity.
Planning Considerations
Many Magnolia homesites rely on private water wells and on-site septic systems. We coordinate the system design and county permitting early, because they affect where the home can sit.
Larger rural lots need planned access roads, culverts and drainage for construction traffic and for decades of daily use.
New and existing slabs can move differently on clay soils. Engineers specify doweling or isolation details so the connection stays sound.
Your current system may not cool extra square footage. We calculate loads and recommend extending ductwork, upsizing or adding a dedicated system.

That is the goal of every addition we build. We match roof pitch, ceiling heights, trim profiles and exterior materials such as brick, stone or siding so the new space looks original to the home.
