Bumping out vs. building up: which way to expand?

I hear you - my place is 1920s brick, and even a tiny bump-out meant a parade of inspectors and a bunch of unexpected insulation requirements. On the other hand, going up would've meant reworking the staircase and messing with the original roofline, which honestly scared me more. In the end, the bump-out was pricier than I thought, mostly due to code stuff, but at least I didn’t have to touch the historic details upstairs. If your house has character features you want to keep, sometimes the hassle is worth it. Have you looked into whether your neighborhood has any historic restrictions? That can really change the equation.

Totally get where you’re coming from - those old houses have a way of charming you into spending more than you planned, don’t they? I’ve seen folks try to “go up” and end up with Frankenstein staircases or weird roof angles that just look... off. At least with a bump-out, you keep the soul of the place intact. The code headaches are real, but honestly, preserving those original details is worth every gray hair. Sometimes the quirks are what make it home.

Funny you mention that - when we looked at adding a second story, every architect wanted to rip out our original staircase. Why is it always the stairs? Ended up doing a small bump-out instead. Anyone else run into weird code stuff with old windows?

It’s wild how often the stairs become the first casualty in these projects. I get why architects want to rework them - old stairs rarely meet modern code for rise/run or headroom - but it’s tough when they’re such a big part of the house’s character. You made a solid call with the bump-out if you wanted to keep that vibe.

Old windows are their own beast. Sometimes you can keep them if you add storm windows or upgrade the glazing, but other times, code wants tempered glass or bigger egress openings, especially in bedrooms. It’s a balancing act: preserving charm vs. meeting safety rules. I’ve had clients fight hard to keep wavy glass panes, only to get tripped up by energy codes... frustrating, but not impossible to work around if you’re persistent.

Funny you mention the wavy glass - I've had folks get really attached to those old panes, too.
