Home additions, designed and built by one team.
Second-story, rear, dormer and gable additions across Greater Boston and Eastern Massachusetts. We draw the plans, pull the permits and build it, so the addition fits the house it joins.

More space without moving
An addition is a structural change to your house, so design and construction have to agree from the first sketch. Because B.A. Perazim is both a licensed builder and an architect, the drawings, the structural plan and the build come from the same team.
We have taken one-story houses to two stories, added rear additions and dormers to Capes and colonials, and built new gables and porticos onto split-levels.
- Second-story additionsRaise a one-story house to a full two-story home, with porches and balconies if you want them.
- Rear and side additionsFamily rooms, kitchens and in-law space added to the back or side of the house.
- Dormers and roof raisesMore headroom and usable rooms in a Cape or attic.
- Gables, porticos and bump-outsSmaller additions that change how the front of the house looks and works.
- Drawings and permitsArchitectural drawings, code review and permit applications handled in-house.
Home additions we've built






“I wanted to do a two family conversion and needed help coming up with the layout for the units. Ransford listened and provided several options on how I could do it. He also had some good ideas and advice along the way about the process of doing the multi-family conversion. In the end, we came up with a cost effective layout that I am happy with.”
