Types of ADUs Gill Construction Builds
Gill Construction works on a range of ADU types, including:
- Detached ADUs — standalone backyard cottages or casitas built on the same lot as the primary residence
- Garage conversions — transforming an existing garage into a livable dwelling unit
- In-law suites — private living spaces designed for family members who need proximity but also independence
- Basement conversions — repurposing existing below-grade space into a functional unit
- Granny flats and guest units — smaller, self-contained spaces suited for extended family or short-term guests
Garage conversions and basement conversions are often a more cost-effective route, since the basic structure is already in place. Gill Construction helps property owners assess whether their existing structures qualify and guides them through the permitting process accordingly.
Most single-family residential properties can qualify for an ADU, though local zoning rules will determine eligibility. Gill Construction reviews each property to confirm it meets the necessary requirements before work begins.
The timeline for an ADU project varies depending on design complexity, permitting, and scope. Typically, projects take several months from start to finish, covering plan review, utility connections, and final inspections. Gill Construction works to keep the process moving efficiently throughout.
Materials and Additional Upgrades
Gill Construction works with a selection of established manufacturers to ensure durability and quality in their builds:
- James Hardie — fiber cement siding suited to Texas weather conditions
- Andersen Windows — energy-efficient windows designed to reduce utility costs
- USG Sheetrock — reliable drywall for solid interior walls
- Sherwin-Williams — quality interior and exterior paints
- GAF Roofing — roofing systems built to handle demanding weather
Many homeowners also use the ADU build as an opportunity to address other property improvements at the same time. Common additions include solar panel installations, landscaping improvements, exterior refreshes, driveway expansions, and smart home features such as lighting controls, thermostats, and security cameras.
On the financial side, adding an ADU can increase a property's value and may also affect property taxes. Gill Construction helps clients understand these implications so they can make informed decisions. Financing options, including renovation loans, are available to assist with construction costs.
Gill Construction's process is straightforward: they collaborate with the homeowner on design and planning, manage the build with attention to detail, and deliver a completed space ready to use. Their focus is on doing the work correctly the first time, reducing the likelihood of issues further down the line.
