Owning & Renovating a Mid-Century Modern Home
Owning a mid-century modern home means caring for things most houses don't have: radiant heat in the slab, flat or low-slope roofs, exposed post-and-beam framing and walls of glass. These guides cover the repairs and upgrades Eichler and mid-century owners ask about most. Each one explains what usually goes wrong, the choices you have and what to ask a contractor, and how to keep the look that makes these houses worth owning. Start with the big systems (heat, roof, wiring), then move on to kitchens, baths, windows, heat pumps, solar and ADUs.
