What separates a glass room addition from a standard sunroom
A glass room addition — also called a conservatory — uses structural glass panels for both the walls and the roof. The result is maximum natural light from every angle: morning sun, noon overhead, evening sky. Done well, it looks like the house was designed with it.
This is our most involved product:
- Structural engineering drawings required (included in our process)
- Custom aluminum or thermally broken aluminum framing systems
- High-performance glass: typically triple-pane with Low-E coatings and solar control
- Full HVAC integration — mini-split dedicated to the space is standard
- 30-year structural warranty
We partner with European glass system manufacturers to bring conservatory-grade quality to Long Island. The end product is genuinely different from a standard sunroom.
Glass room addition cost: $55,000 – $130,000
This is our premium category. Cost range depends on:
- Size (200–500 sq ft typical)
- Glass specification (standard Low-E vs. high-performance solar control)
- Roof style (pitched glass, flat glass, Victorian ridge)
- Foundation requirements
- HVAC approach (mini-split is standard; we coordinate)
Glass Room Addition FAQ
Yes, and we handle it. Every glass room addition project we do includes stamped structural drawings from our engineering partner. This is required for Nassau and Suffolk County permits and ensures the structure performs correctly under Long Island's snow load requirements.
All our glass room additions use high-performance solar control glazing — typically Solarban or similar — that rejects 60–70% of solar heat while maintaining visibility. Combined with a dedicated mini-split, these rooms are comfortable year-round.
