Why Add a Glass Room
More Living Space Without Losing the View
Too many Houston-area patios sit unused. Heat, humidity, mosquitoes, sudden rain, and Gulf Coast wind turn what should be a favorite part of the home into wasted square footage. Builder-grade screen rooms and bolt-on additions rarely solve the problem — they look cheap, perform poorly, and don't last.
A properly built glass room from Simmons Home Design changes that. We design and install custom glass rooms, sunrooms, four-seasons rooms, and vinyl window enclosures that add year-round comfort, natural light, and protected outdoor views — while looking like they were part of the home from day one. It's a sunroom addition done right for Houston-area living.
Why It Matters
Designed for Comfort, Light, and Long-Term Performance
Every glass room we build is engineered for the realities of Gulf Coast living — heat, humidity, storms, and the way Texas homeowners actually want to use their outdoor space.
Windstorm-Conscious Construction
Built to applicable windstorm requirements with materials and connections designed for coastal weather, not generic patio kits.
Vinyl Window Options
Prefer airflow and a lighter budget? Vinyl window and Eze-Breeze-style enclosures still block bugs, rain, and debris — without giving up the outdoor feel.
Custom Fit to Your Home
No prefab boxes. We design every room around your roofline, slab, sightlines, and how you actually want to live in the space.
More Usable Square Footage
Reclaim a patio that's too hot, buggy, or exposed and turn it into a true living space — morning coffee, evenings, holidays, all year.
Owner-Led Process
You work directly with the owner — clear answers, straight estimates, and one accountable point of contact from first call to final walk-through.
Integrated Design
A Sunroom Addition That Feels Connected — Not Added On
The difference between a premium glass room and a cheap patio kit is obvious the moment you walk up to the house. Rooflines should flow. Posts should land cleanly. Trim, color, and proportions should match the home.
We pay attention to those details so your finished room reads as part of the original architecture — adding value, light, and usable space without looking like an afterthought. Pair it with a matching patio cover, screen enclosure, or pergola for a complete outdoor living build.

Choose Your Build
Glass Room, Sunroom, or Vinyl Window Enclosure?
Each option fits a different goal, budget, and lifestyle. Here's how to think about it — and we'll help you confirm the right choice during your on-site consultation.
Glass Rooms
Also called: four-season sunroomsA fully enclosed, climate-conscious room built primarily with insulated glass for maximum light and panoramic views. Best when you want a real year-round indoor-outdoor living space — a true four-seasons room.
- Double-pane insulated glass
- True year-round comfort
- Adds living square footage
- Highest resale impact
Sunrooms
Three-season or four-season buildsA broader category of enclosed outdoor rooms — combine solid roof systems, glass walls, or window walls depending on your goals for light, shade, and ventilation. Popular as a 3 season room for Houston-area patios.
- Custom roof & wall combinations
- Great for shaded comfort
- Strong value per square foot
- Adaptable to most patios
Vinyl Window Enclosures
Eze-Breeze-style window systemsAn affordable way to enclose a patio while keeping the open-air feel. Vinyl window panels block rain, bugs, and debris but still allow airflow when opened — a great fit for existing covered patios.
- Lower price point
- Keeps the breeze, blocks the bugs
- Great for existing covered patios
- Quick to install

FAQs
Glass Rooms & Sunrooms FAQs
Quick answers to the questions Houston-area homeowners ask us most.
How much does a glass room or sunroom cost in the Houston area?
Custom glass rooms and sunrooms in the Houston area typically range from about $15,000 to $50,000+, depending on size, glass package, roof system, structural requirements, and finish details. Smaller vinyl window enclosures usually start at the lower end of that range, while full insulated-glass four-seasons rooms with custom rooflines run higher.
Simmons Home Design provides custom on-site estimates for every project. Call 346-617-4031 or request a free quote for accurate sunroom cost numbers based on your home.
What is the difference between a glass room and a sunroom?
A glass room is typically a fully enclosed structure built primarily with insulated glass panels for maximum light and a true year-round indoor-outdoor feel — often called a four-seasons room. A sunroom is the broader category and can include solid roof systems, glass walls, vinyl windows, or combinations of all three (3 season rooms are a common variant). Both add usable living space; the right choice depends on how much light, climate control, and budget flexibility you want.
Do you offer vinyl window enclosures?
Yes. Vinyl window enclosures — including Eze-Breeze-style window systems — are a popular, budget-friendly option for homeowners who want to block rain, bugs, and debris without giving up airflow or the open-patio feel. They're a great fit on existing covered patios in the Houston area.
Are your glass rooms built to windstorm requirements?
Where applicable, yes. We design and install glass rooms to meet the windstorm requirements that apply to your address along the Texas Gulf Coast. Specific requirements are reviewed during your on-site consultation and confirmed before construction.
Do glass rooms use double-pane insulated glass?
Yes. Our standard glass rooms use double-pane insulated glass to help with energy efficiency, sound reduction, and Gulf Coast temperature swings. It makes the room far more comfortable year-round than single-pane builds.
Can a glass room be added to an existing patio?
In most cases, yes. We evaluate your existing slab, footings, and roof structure to determine what — if any — modifications are needed before we can safely build the glass room on top of it. We'll walk you through this during the consultation.
Do glass rooms help with bugs, rain, and outdoor debris?
Absolutely. A properly built glass room or vinyl window enclosure keeps out mosquitoes, rain, leaves, pollen, and outdoor debris while still giving you full outdoor views and natural light. For many homeowners, that's the single biggest reason they finally use their patio.
Do I need HOA approval or permits?
Most glass room and sunroom projects require permits, and many HOAs require approval before construction. We help you understand what's needed and prepare the documentation during the design phase.
What areas do you serve?
Simmons Home Design serves the Greater Houston and Texas Gulf Coast region, including Angleton, Houston, Pearland, League City, Friendswood, Webster, Clear Lake, Alvin, Manvel, Katy, Cypress, Tomball, Conroe, and the surrounding Brazoria, Galveston, Harris, Fort Bend, and Montgomery County communities.

Planning for HOA Approval?
Many associations request drawings, dimensions, colors, and material information before reviewing an outdoor structure. Use our free Texas planning guide and printable checklist to organize the process before construction.
Simmons Home Design can provide applicable project-specific information included in the written scope. HOA requirements vary; homeowners remain responsible for confirming and submitting their association's application unless the written SHD agreement states otherwise. Approval cannot be guaranteed.
