I restore these on weekends and sell them on weekdays, which means I have opinions about which problems are worth having. The good news for anyone about to buy a Krisana Park Wolff or a Table Mesa Wagener is that mid-century houses were, on the whole, built honestly. The bad news is that the specific ways they fail are expensive and are not what a general inspector is looking for.
The roof deck is the whole question
A post-and-beam house has no attic and no truss. The tongue-and-groove decking you see from inside is the roof structure, and it is also the ceiling. That is why the interiors are so good and it is why a leak is a structural event rather than a stain.
What to look for: any sag between beams, any darkening at the perimeter, any spot where a previous owner has added a skylight or a mechanical penetration. A skylight cut into a post-and-beam deck by someone who did not understand the load path is the single most expensive thing I find in these houses. Get a structural engineer up there before your inspection deadline, not after. It costs a few hundred dollars.
Verdict: a five-figure problem, and a legitimate reason to walk.
Radiant slab heating
Many of these houses heat through copper or steel tubing embedded in a concrete slab. When it works it is the best heat there is. When a loop fails, you are opening the floor.
Ask whether the system has been re-zoned or partially abandoned, and whether the boiler is original. A system that has been converted to PEX in a new topping slab is fine and often better. A system running on original 1955 copper with no service history is a bet. 1275 S Jasmine had its slab re-zoned in 2020 with the scope on file, and that document is worth real money to a buyer.
Verdict: a bargaining chip if undocumented, fine if it has been addressed.
Single-pane clerestory glazing
The clerestory band is the reason to own the house. It is also, in its original form, a single sheet of glass in an aluminium frame with no thermal break, and it will be the coldest surface in Colorado in January.
Replacing it correctly — matching the profile, keeping the sight lines, insulated glazing — is achievable and costs what you would expect. Replacing it badly destroys the thing you bought. 1855 Kohler Drive had its windows replaced in 2021 with a matched profile and it is the reason that house prices where it does.
Verdict: budget for it, do not discount the house for it, and do not let anyone put vinyl in.
Original electrical
Sixty-amp service, two-prong outlets, possibly cloth-sheathed wiring, occasionally aluminium branch circuits from a 1960s update. None of this is dangerous in the abstract and all of it is a problem for your insurer.
A service upgrade to 200 amps with a new panel is a known quantity. Rewiring a post-and-beam house with no attic and no basement, on the other hand, means opening finishes. Ask what is accessible before you assume a number.
Verdict: a bargaining chip. Get a quote during the inspection period.
Things that look alarming and are not
- Hairline cracks in a slab. Nearly universal, nearly always cosmetic. Look at width and displacement, not presence.
- Original kitchens and baths. Frequently the most valuable rooms in the house to the buyer who wants what you want. Do not price them as a renovation you must do.
- Small bedrooms. They were designed to be small so the living space could be generous. That was the point.
- No insulation in the roof. Addressable from above with a new membrane and rigid insulation, without touching the interior deck.
The thing nobody tells you
The market for intact mid-century is not the general market. It is a small number of buyers who know exactly what they are looking at, and they pay a premium for originality — which means that every "improvement" you make away from the original is a subtraction at resale. If you want an open-plan kitchen island, buy a house that already has one. If you want the Wolff, buy the Wolff and leave it alone.
There are currently three Krisana Park houses on this site, and I am happy to walk any of them with you and tell you what is wrong with it.
