Wraparound Deck Cost by Size

A wraparound deck runs along two or three sides of a house — common on Victorian, ranch, and cottage architectures. Creates multiple outdoor access points from interior rooms.

Best for

Older homes with multiple back-of-house entrances, narrow lots where length compensates for shallow depth, walkout basements with grade variation.

Watch-outs

Inside corners can trap snow and ice in cold climates — frame with continuous drainage in mind. Ledger flashing detail must be perfect across every joint.
