Seven months ago this custom home was just a foundation. Today the brick is on, the windows and doors are in, and it finally reads as a house.

I was back on site this week for a construction administration walkthrough, which is the part of the process most people never see. It’s where I verify that what’s actually being built matches what we designed. On this visit that meant checking the brick sill and soldier courses, confirming the weep holes were installed correctly, catching a trim detail that got missed, working through a shower that started as a window and became a transom, and reviewing the rafter clearances for the elevator that has to reach the third floor.

Here’s the thing about weep holes, since they come up in the video. Brick veneer isn’t waterproof. Water gets behind it, and those small gaps at the base of the wall are what let it drain back out instead of soaking into the structure. Miss them and you’ve built a problem into the wall. It’s exactly the kind of detail that’s cheap to get right during construction and expensive to fix later.

The builder on this one is good and moves fast. On a custom home, the architect on site is the layer that makes sure fast never means a detail gets buried.

Full walkthrough is up on YouTube. Link in the first comment.

How do you get a zoning variance approved? We just walked one through, so here’s how it actually works.

Our client purchased a property with an existing house. The house was torn down, and in the meantime the town updated its zoning laws, which left the lot nonconforming. On a nonconforming lot, you can’t simply apply for a permit and build. You need a variance.

A zoning variance is approval to build when the physical lot can’t be changed to meet the current requirements. To get one, you appear before the zoning board of appeals and demonstrate two things: that the lot itself cannot conform, and that everything you intend to build meets the rest of the zoning code.

We came in with a clear plan, made that case, and the board approved it. Our client can now move forward with his dream home.

If you’re facing this, the most important thing to know is that the board is made up of your neighbors, everyday people deciding what happens in their community. Showing up with a solid plan and an architect who knows the code and can clearly explain it makes all the difference.

We took this 100-year-old house down to the studs, and the framing told on itself. 👀

We took this historic home down to the studs to convert it back into a duplex, and found double 2x10 headers sitting on nothing. No column, no support, just floating there for who knows how many decades.

That wasn’t even the only surprise. The board and batten walls are actually structural, and you can see the exact seams where the original house stopped and two additions got tacked on over the years.

Here’s the lesson: an old house never tells you the truth until you open it up. Survey the bones first, and you can bring it back to life the right way. Skip that step, and the house decides your budget for you.

Most custom homes in Buffalo play it safe. This one doesn’t.

Renderings are done and we submitted for building permit today! Scroll through to see the interior.

The Thomas Residence is a modern, design-forward custom home built to a level of material craft you don’t see often in this market. The exterior pairs slate composite siding from Cupa Pizarras with crisp white stucco, aluminum-clad Pella Windows and Doors, and warm thermally modified wood accents. It is a restrained, high-end palette that lets the architecture speak.

Inside, we maximized the buildable space and added a full master suite: a sitting room entry with the bedroom and bath on one side and a custom walk-in closet on the other. The living, dining, and central entry are fully open, and rather than chopping those spaces up with walls, we shaped the ceiling to define distinct zones and paths of travel. Leave a comment and let me know if you think we pulled it off.

Like always, I’m on this one through construction administration, start to finish. Can’t wait to break ground and share construction progress.

This home blends traditional and modern architecture. The carriage house doors and brick read as traditional, while the horizontal panel orientation on the doors pulls the design in a modern direction. It is a small detail that changes how the entire facade reads, and it is exactly the kind of decision that separates a true custom home from a production build.

This is the kind of custom residential work that rewards a construction-first architect who details every material and transition with intent, from the motor court approach to the way the brick meets the siding.

David Stumpf Architecture is restoring a 1920s bungalow at Champion Lakes Golf Resort in Bolivar, Pennsylvania, converting a former rental into a historic guest house.

On this site visit we walked two active projects on the same campus. The carb barn restoration continues to progress, but the focus was the house across the street: a 1920s craftsman bungalow the resort purchased and is now transforming into guest accommodations.

The design approach was simple and classic. The existing white exterior stays, the dated green accents come off in favor of black trim, and the original wood door is preserved. We reworked the floor plan and added two guest rooms on the rear of the house.

The architectural reference is low country design, the elevated, historically detailed style found in Savannah and Charleston. Applied to a Western Pennsylvania bungalow, it produces a building that reads as authentically historic rather than simply renovated. This is the kind of historic restoration and adaptive reuse work that rewards a construction-first architect who details every material and transition with intent.

The clubhouse restoration on the same campus is also underway.

The foundation is the one phase of a custom home you can never go back and fix.

A few weeks ago this house was just lines on paper and footers buried in snow. Last week I was on site walking the poured foundation, checking it against the construction drawings before framing starts. Beam pockets, wall offsets, brick ledge transitions, egress openings, plumbing rough-ins, the elevator pit drain; all of it verified while it is still exposed and still correctable.

The reason this matters: a small mistake in the foundation extrapolates through the entire building. Catch it now, on the concrete, and framing goes smoothly. Miss it, and you are fixing it three phases later at ten times the cost.

I walk every one of my projects at this stage. If you are planning a custom home and want to understand what actually happens at a foundation review, the full walkthrough is worth ten minutes.

First comment for the video.

The most expensive mistakes in construction are the ones that look correct.

Five months into this custom home build, everything fit. The windows fit the openings. The openings fit the windows. The rooms looked clean.

And both were wrong. The supplier had delivered the wrong windows, and the framers had built to what showed up instead of what was drawn. The only thing on that site that disagreed was the construction documents. The documents are the only thing that matters.

That's the second wrong window order on this project. Both died before drywall because two independent layers were checking the work against the drawings: a builder running a tight, disciplined jobsite, and an architect showing up for site inspections. Limpert Construction and I worked the solution together; replacement units, corrected framing, sill lines realigned.

Caught after drywall, that's demolition, reorders, schedule slip, and a fight about fault. Caught at rough-in, it's a conversation and a supplier correcting the order.

Owners and developers treat construction administration as an optional line item. It's the layer of independent verification that protects every other line item, and most projects skip it entirely.

If you want to see how this works in the real world. I've linked the full final framing inspection video in the first comment.

Yesterday I walked through a building that I have not been able to stop thinking about.

David Stumpf Architecture met with the owners of Saint Francis de Sales Church at 575 Humboldt Parkway in Buffalo to talk through the possibility of bringing this extraordinary building back to life as a wedding venue. We toured the building, assessed the conditions, and we are now drafting a proposal to make it happen.

Here is what we are working with:

The building was designed in 1928 by George Dietel, the same architect who designed Buffalo City Hall, in collaboration with Washington DC firm Murphy and Olmsted. It is 23,130 square feet of Italian Romanesque Revival architecture built entirely of Indiana limestone with no structural steel. A 140 foot campanile tower. A polychrome barrel vaulted ceiling by the Raphael Guastavino Company. Mosaics on the interior walls inspired by the ancient churches of Ravenna, Italy. And at the crossing of the nave and transept, a dome with an oculus that pulls natural light deep into the sanctuary. At the right time of day it casts a beam of light into the space that no artificial lighting could ever come close to replicating.

This is a moment built into the architecture of the building itself, one meant to inspire awe. For us it becomes a once in a lifetime wedding moment. Imagine a first dance in the center of the room, lit by a natural spotlight, and directed by the building itself.

The building has been abandoned since 2013 and the challenges are real and significant. The limestone exterior shows evidence of what appears to be improper pressure washing or sandblasting at some point in its history, which likely destroyed the mortar joints across the entire exterior and stripped the protective layer from the stone, allowing water to work its way behind the facade at multiple points. The apse roof behind the sanctuary has lost its protective covering. Two of the three rear ceramic tile domes have lost their tile and are fully exposed to the elements. The basement has active water infiltration. The interior has been stripped of nearly everything.

This is a serious project. It is also a Buffalo landmark and a contributing structure in the Hamlin Park Historic District on both the State and National Registers of Historic Places, which means historic rehabilitation tax credits are available to help offset the rehabilitation cost.

The vision is not drop ceilings and bare drywall. It is restoring what this building was always capable of being and creating an experience that every bride, every guest, and every person who walks through those doors remembers for the rest of their lives. The architecture does the work. Our job is to bring it back.

We are drafting the proposal now. Stay tuned.

If you have worked on a project like this, dealt with historic limestone in a similar state, or have experience with masonry restoration at this scale, I would love to hear from you in the comments. Any pointers, recommendations, or lessons learned from the field are welcome. Leave a comment below.

Most homeowners never see this.

By the time your foundation is backfilled the waterproofing system behind it is gone forever. You will never know if it was done right until water shows up inside your home years later and by then the fix is expensive.

On this site visit David Stumpf Architecture walked the full exterior foundation of this custom transitional home in the Pittsburgh area before backfill, reviewing the 60mm fluid applied waterproofing membrane, the protection board system, the Zip System weather barrier installation, and the interior and exterior drainage system that works together to keep water out for the life of the building. Not only does he review those systems, but he also discusses the different alternative waterproofing methods, and what happens if it isn't done correctly.

Two conditions were flagged and addressed before work continued. This is what construction administration looks like on a custom home built to last.

This is part three of our full build series. Link in the comments!
