Four-Season Sunrooms · MetroWest Boston

A four-season sunroom addition you use every day of the year

What it is

A room for January, not just July.

Walls, insulation, real heat — a four-season sunroom is a true addition, built to the same standard as the rest of your house and then filled with glass. You get the light and the views of a sunroom, without the calendar: it holds its comfort straight through a New England winter.

A summer-only sunroom sits closed for half the New England year. A four-season room is built and insulated so you never lose those months — it's living space you use in January just as much as July.

What's included

A sit-down at your house about how you'll use the room in January as much as June
An insulated design drawn to your home's roofline and style
Glass and building choices picked for New England weather, not a national average
Permit drawings, filings, and your town's reviews — carried by us
One team from the footings to the final walk-through

The outcome: A true extra room — a den, a dining spot, a home office — that you reach for in every season, not just summer.

Why add one

Real square footage that works in January.

Living space, all twelve months

A finished, heated, insulated room — permanent square footage that doesn't close for the winter.

More house, same address

A den, a dining room, an office, a plant room — the most flexible space you can add without moving.

Built to belong

Materials and rooflines matched to the house, so it reads as original — and buyers can tell built-right from bolted-on.

A four-season room with a solid painted ceiling and windows on three sides, looking out over the water. — A solid roof overhead, glass on three sides — softer light, and a ceiling that feels like the rest of the house.

The way you live

The winter changes first.

The room that used to close in October stays warm — morning coffee with snow on the glass, plants that keep growing, a bright place to work while the yard sleeps.

Then the rest of the year follows: dinner drifts out there in June, homework lands there in September. A four-season room doesn't just add a room — it adds hours. The bright ones.

A plant-filled sunroom with a solid painted ceiling, a hanging rattan chair, and pots of greenery along the windows. — Reading, plants, nap time — the room takes all comers.

Materials & roofs

Your room, your materials — and the roof decides the light

Three framing materials

Four Seasons rooms come in sleek aluminum, efficient vinyl, or warm natural wood — we help you pick what fits the house and the budget.

Aluminum — slim frames, the most glass, modern lines
Vinyl — efficient and low-maintenance
Wood — warm, natural interior beams

Choose aluminum for the most glass and the slimmest frames; vinyl for the lowest maintenance; wood when you want warm beams overhead. We bring samples to the consultation — most people know within minutes of holding them against the house.

Two roofs

Glass overhead or solid overhead — it changes how the room feels at noon and at midnight.

Sun & Stars — an insulated glass roof (ConservaGlass NXT), for sky all day and stars at night
Sun & Shade — a solid insulated roof, for softer light and a cozier room
Cathedral or straight-eave profiles, matched to your roofline

Choose Sun & Stars if the sky is the point — plants, stars, light all day. Choose Sun & Shade if you want softer light, less summer heat, and a ceiling that feels like a living room.

Neither decision is forever-fraught: the frame follows your house, the roof follows how you'll use the room. Both usually settle themselves at the in-home consultation.

Four-Season Sunrooms · questions

Questions homeowners ask

What's the difference between a three-season room and a four-season sunroom?

A three-season room is lighter-built — glass instead of screens — and it's at its best from spring through fall. A four-season sunroom is a fully insulated, heated addition, so it stays comfortable all year, including a New England winter. We help you choose from how you picture using the room, not from a spec sheet.

Will it be too hot in summer or too cold in winter?

Built right, no. A four-season room uses insulated construction and energy-minded glass so it holds a comfortable temperature across the seasons. We design for the New England climate specifically.

Can you convert my existing three-season room, deck enclosure, or porch into a four-season sunroom?

Often, yes — the Four Seasons system is designed to upgrade. On many rooms the change from three-season to year-round is a window swap completed in hours, not a rebuild. We confirm what your room needs at the consultation.

Do I need a building permit?

Yes — a four-season room is a true addition, and every town we serve permits it like one. The drawings, the filings, and the local reviews (historic districts, conservation, zoning) are our job, not yours.

How much does a four-season room cost?

There's no honest one-size number — size, framing, glass, and heating all move it. What we can promise: the free in-home consultation shows you exactly which choices drive the price, so the budget conversation is a real one.
