Hell that looks VERY similar to the one in the house I grew up in--which my Gramps and my Dad built, when he was still in high school, just before WWII I'll see if I can find a photo. It was the subject of a really sad sale by the hands of "the person formerly known as my sister" if that gives you a clue

This is after the house sold and under a pretty complete renovation. Notice the ceiling joists those are 2x TEN. This is taken from the main bedroom. The thing originally had a tiny, almost square "hallway" and you would come in from the door frame at the right of the photo from the living room. So the "hallway" had 4 openings, the living room, the stairs, the bath (straight ahead from living room) and the bedroom towards the camera

There is no plywood, "packi board" or OSB in this house. Floor joists and roof rafters were "rough" "real" dimension 2x, and just as sound today as in 38 when work was started. Sheeting and subfloor is tongue and groove 1x xx board

Cool to see.

This house was possibly built sometime between 1850 -1870 as an estimate.

Stone foundation, mortise & tenoned beams & supports with wooden pins pounded through to hold the joints together. Some of the rafters were milled on all for sides, but some are small poles with one side hewn flat & originally it had a slate roof.

On some of the larger barn timbers you can see adze marks.

The house is too far gone to save, but the owner is paying me to save as much as the old wood as possible.

Some of the T&G floor planks I pulled up today were around 22 inches wide.

If he does want this stairway, it may work for loft access in my shop.
 
I have built winder stairs before, but not one with every step as part of the wind.

I'd call this one a Dusty Twister.

(especially if I do get to use it in a Mopar shop) ;-)
 
That's generally what we see in 18th-century and into 19th either as the only staircase or the secondary one.

Not sure how much I have digitally. Lemme look.
 
This one was one of two into the attic, BIG attic though.

The other staircase is a winder also but only at the low 90 degree corner at the bottom.
 
This is pretty early survivor for SE Pa. Probably around 1730
Although it may not look it in the photos, this was a better than average house at the time.

If doing more than a 50% renovation, then everything must be brought up to current codes. The IBC says that the minimum tread depth on winder treads is 6”.

So the treads that taper down to nothing are not code compliant today. Just sayin’ for a friend.
 
You may have missed a post above, the house will be demolished after all the good wood is saved.
 
Update! I measured the stairway today, 38" wide & it is 1/2" taller than my loft floor. The loft has a 1/2" plywood floor on 24" centers right now, so it is on the weak side. So..... add stairway, add a lift to the floor to make up the difference & done!

I mentioned it to Roger & he laughed then said, 'By all means, help yourself, it's yours!" :)

The stairway salvage will begin in the morning.
 
Just to complete the pictures I posted yesterday, here's an early post card of the house.
The shed addition to the rear, and the second main block (left of main chimney) are very early additions, prob 1730s

Cool to see! The oldest house I have worked on so far was built in 1735.

I do love history. :)

I don't think that applies, exactly. A quick search shows up...................Of course some local codes might be more strict.........

Spiral Stair Building Code Compliance
  • Minimum stair diameter of 60" for a metal stair and 64" for a wood stair
  • Tread path between handrail and center column a minimum 26"
  • Center tread width, 7 1/2" in from the narrow end of the tread d
  • Headroom minimum of 6'6"
  • Riser height cannot exceed 9 1/2"
  • Baluster spacing of no more than 4" (to prevent children from sticking their heads between balusters)
  • Minimum height of the handrail of 34" from the tread nosing to the top of the handrail
  • Landing width, 4" longer than the tread path
  • Rail height on the landing, well and balcony rail has a minimum height of 36"

i remember building a loft to fit my spiral staircase
good times
 
The stairway is out. :)

I also found my first ever open pontil bottle in between wall studs at the bottom, broken though. :-(

I also found the well, ground water is still streaming into the bottom. :)

well its a deep subject.JPG
 
More nails pulled, all parts prepped for reuse whenever that time comes.......

I'll store the 33 piece puzzle kit inside for now.
