Why Legion Build

A sunroom built like the rest of your house — not bolted onto it.

Most sunroom companies install a prefab kit. We're a full-service NJ building company, so your sunroom is framed, roofed, and finished as a true addition — sized for your space, your sun exposure, and how you actually want to use the room.

01 — SEASONS

Three-season or four-season

Open-air screen rooms, insulated three-season spaces, or fully conditioned four-season additions. We talk through the trade-offs before you spend.

02 — INTEGRATION

Built into the house

Matched siding, roofline, and trim so the addition reads as part of the home — not a glass box stuck to the back.

03 — PERMITS

We handle the paperwork

Additions trigger more paperwork than a deck. We deal with the township, architect coordination, and inspections so you don't chase it.
