Houses in Avalon climb the hills above the harbor, and from many decks you can see the Casino, the boats on their moorings and open water beyond. Those views are the whole reason a lot of people live on Catalina Island, and a glass sunroom is one of the few additions that keeps them front and center while giving you shelter from wind and fog.
Built for Life by the Ocean
Island weather is dominated by the ocean. Summers are mild, marine layer mornings are common, and afternoon breezes can be stiff. Salt air is part of daily life. Cthru and Four Seasons sunrooms use aluminum framing, and every room is custom made to order, so it can be designed for the specific exposure of your home. We look at wind direction, the angle of the lot and the views you want to keep during the estimate.
Which Sunroom Style Suits an Avalon Home?
Avalon’s housing is a mix of small cottages, older bungalows, condos and larger hillside homes. Here is how each style tends to fit:
- Curved eave: A curved eave sunroom carries glass from wall to roof in one sweep, so you see sky and water with no hard corner overhead. A good match for a view deck.
- Straight eave: A straight eave sunroom has a crisp, compact profile that fits the small footprints and tight spacing of many in-town lots.
- Cathedral or studio: Taller rooms with peaked or single-slope roofs, useful on hillside homes where the attachment wall is high.
- Conservatory: Victorian and Georgian conservatories bring a classic look that complements Avalon’s older architecture.
Single or Dual Pane Glass by the Sea
Avalon rarely sees the extreme heat of the mainland valleys, so glass choice here is more about comfort on cool, damp days and on bright afternoons when the sun reflects off the water.
Single pane glass is the lower-cost option and can work well for a room used on fair-weather days. Dual pane glass insulates better, keeps the room warmer on foggy mornings and winter evenings, and helps cut condensation. With either choice, the glass blocks harmful UV, which protects furniture and flooring from the intense glare off the harbor.
Decks, Slabs and Hillside Lots
A lot of Avalon homes have decks rather than ground-level patios, because the terrain is steep. Sunrooms can be built on a sturdy deck, but we inspect the deck first to confirm it can support the room. Where there is a concrete slab, that is the simplest base. Every room is matched to the home’s architecture, so it looks like part of the house rather than an add-on.
Features, Warranty and Next Steps
Common options include retractable shades, ceiling fans, lighting and outlets with hidden wiring, and heating for cooler months, either tied to the house or standalone. See the full list on our product features page.
Permits may be required through the city’s building department, and we cover that during your free, no-obligation estimate, along with the extra planning that comes with building on the island. Products are made in California and carry a lifetime transferable manufacturer warranty. Once materials are on site, installation of a sunroom takes about 3 to 5 days.
