Second Story Additions in Cambridge
A New Upper Floor for Your Cambridge House
From old working-class East Cambridge to large older homes near Harvard, the Red Line ties together very different neighborhoods. When a Cambridge family needs more room without a bigger footprint, we build a full or partial floor, with the roof removed in planned sections and open areas covered whenever work stops.
Work on a new floor we handle in Cambridge:
- Second stories for homes in East Cambridge
- Roof removal in planned sections
- Temporary shoring while the house is open
- Full or partial floors over the existing house
- New stairs linked to the rooms below
Local conditions
Building Up on Cambridge Houses
Large older homes near Harvard often carry many rounds of updates, and some may still have dated wiring or tired framing. On any lot, a second story keeps the existing footprint, so most of the work happens up top, with temporary shoring in place and dust barriers inside.
What we review before design:
- The footings below the walls
- Beams and posts that may be needed
- Room for the new staircase
- Shoring during roof removal
- Plumbing for bathrooms upstairs
Signs building up may suit you:
- Lot lines leave little room beside the house
- You need space for relatives or guests
- A move does not feel like the right answer
- One wing could carry a new level
- You need more space without touching the yard
At the free estimate, we check the roof, where the new staircase can go, and the electrical panel, water heater, and HVAC, since each of them affect how the new level is framed and what it will cost.
Our process
From Roof Removal to New Floor in Cambridge
A second story in Cambridge follows a strict sequence: structural evaluation, temporary support, roof removal, reinforcement, framing, systems, and finishing. Each step is planned before the old roof is opened, since the house stays open to the weather until the new floor is closed.

Cost factors
Pricing a New Floor in Cambridge
The engineer’s review has a large effect on the cost of a second story for a Cambridge house. Walls and a foundation that call for beams, posts, or larger footings add extra work a sound structure avoids, so we wait for that review ahead of the price. Roof design, stairs, bathrooms upstairs, and finishes count too.
The price depends on:
- Square footage of the new floor
- State of the foundation and walls
- Reinforcement the engineer requires
Also in the estimate:
- Removing and rebuilding the roof
- Systems and bathrooms upstairs
- The new staircase and materials

FAQ
Second Story Additions in Cambridge: Common Questions
Here are short answers to the questions Cambridge homeowners ask when they plan a second story: permits and structural drawings, structural reinforcement, the roof, and how the free estimate works. Need more detail? Phone our team, and we will go over the options for your house in plain language.
What permits does a second story in Cambridge need?
A building permit with structural drawings stamped by an engineer, and in many towns a zoning review of building height. Inspections cover the structural work, the framing, the wiring, plumbing, and HVAC, the insulation, and the final work. We coordinate the engineer, file the applications in Cambridge, and schedule each inspection.
How do you know a Cambridge house can hold another floor?
An engineer’s evaluation settles it. Before anything is drawn, the engineer reviews the foundation, the walls, the floor framing, and the load paths down to the ground. The results tell us what reinforcement is needed, such as beams, posts, larger footings, or new framing, and we quote the project only after that evaluation.
Do you take the old roof off?
In most cases, yes. A second story over the whole house usually means taking off the existing roof so the new floor can be framed on the walls, while a partial addition may only open one section. The roof comes off in planned sections, and we cover whatever is open at the end of each day.
