Should you renovate or move?

Most Boston homeowners run the math wrong, because they only count the renovation cost. They don't count what it actually costs to sell and buy.

On a $1.2M sale and a $1.6M buy, you're out $110,000 to $200,000 just to switch houses. Before you've gained one extra square foot.

That same money, spent on the home you already own, can build a second story, a roof deck, or a full kitchen rebuild. With most of it coming back at resale.

If you locked a 3% mortgage and you're thinking about giving it up to chase more space, this is the post you wanted before you called a realtor.

Save this. Send it to anyone you know who's deciding.

A South Boston corner parcel. The Lavey family home for generations. Now five luxury condos.

When the Laveys decided it was time to sell, we worked with them to take over the property and rebuild what had been there for over 130 years. The house came down. A modern five-unit ground-up building went up in its place.

Getting from idea to permit was its own project. The original plans for 5 units and 5 off-street parking spaces triggered zoning violations and required ZBA approval. That meant on-site meetings, conversations with direct abutters, sit-downs with civic leaders and reps from elected officials, and gathering signatures across the block. The community backed the project. The ZBA granted the variances.

12 months of build. Pella windows, James Hardie lap siding, PVC trim. Modern design that still fits its corner.

We spend a lot of time preserving historic Boston brick, but this destination takes "historic masonry" to an entirely different level. Can you guess where we are?

Here are your hints:

It features some of the most incredibly preserved ancient Roman city planning and architecture in the world.

You can still walk the original stone-paved streets and see the structural layouts of homes built over 1,900 years ago!

The entire city was famously frozen in time by a massive volcanic eruption.

157 O Street, South Boston.

Started as a 1900s single-family row house. Will finish soon as a fully reimagined modern home with a rear addition, rear decks, a roof deck, and a backyard, all on the same footprint plus the ZBA-approved expansion.

Designed by Derek Rubinoff. Interior selections by Stanton Schwartz Design Group. Radiant heated floors throughout, custom designer closets, high-end kitchen and bath finishes.

Most homeowners hear "full gut" and picture demolition. The demo is the easy part.

A real Boston full gut runs 6 to 18 months across 7 stages. Each one has a real timeline. Each one is where projects can go right or wrong.

Swipe through and save this before your next renovation. If you've ever been told "it'll be ready in 4 months," this is the post you wanted six months ago.

New project on South Boston's East Side. A short walk to L Street Beach.

Four units. Off-street parking for every one of them. Two 3-bedrooms and two 2-bedrooms, all with high-end finishes. Rear decks at each unit and a large common roof deck on top.

The East Side keeps getting better. We're glad to be part of it.

Revere Street, Beacon Hill. A 30-year-old common roof deck, completely rebuilt.

The deck wasn't the only thing that needed work. Before we could rebuild it, the entire roof underneath had to be replaced. That's the part most homeowners don't see coming: a deck rebuild is often a roof rebuild plus a deck rebuild. Sequencing matters.

Custom metal work on the head house. New deck surface. And the part no contractor can take credit for: views straight out to the Charles River.

Beacon Hill is one of the strictest historic districts in Boston. Building anything up here means working within rules that protect what makes the neighborhood look the way it does. We've been doing roof decks in this city for a long time. This is one of the projects we're most proud of.

Now that the weather's turning, this is the season decks get used. If yours is aging out, this is the time to plan.

We spend our days building across Boston, but a great builder always keeps their eyes open for global architectural inspiration! Can you guess where this stunning coastal town is located?

Here are your hints:

It features beautifully preserved, brightly colored 14th-century facades cascading down a steep hillside.

Building on this kind of severe incline required centuries-old masonry and incredibly strategic structural engineering!

It boasts one of the deepest natural harbors on the Mediterranean Sea.

It’s tucked right between Nice and Monaco on the Côte d'Azur.

799 East Third Street started as a single-family home on South Boston's East Side.
By the time we were done, it was four multi-story luxury townhomes on the same footprint.

These four-story townhomes were designed with luxury finishes and a focus on livability. Special attention was given to the kitchens and bathrooms, ensuring no detail was overlooked. Each townhome includes 3+ bedrooms, with additional space for home gyms and ample storage, making them perfect for families or individuals looking for spacious urban living.

The East Side has changed a lot in the last decade. The block at East Third is one of the corridors where you can see the shift in real time, and we've been lucky to do meaningful work along it.

Windows you can feel.

Pella at 532 E Third Street, South Boston. The right window package can change how a building lives, sounds, and looks from the sidewalk.

We've installed Pella on enough projects to know which lines hold up. They show up on time, the hardware is consistent, and the field reps actually answer when you call.👍🏻
