From the Field: Framing the “Right-Sized” Oak Park home

Framing is great fun to watch--it goes up fast, and in a few weeks you go from having drawings to being able to walk through real enclosure of space. It's like the week after Halloween to an architect: lots of eye candy! Evolutionary Home Builders has been doing their...

Manifesto: the new American dwelling

The single-family home is a great American dream, one that so many of us have been fortunate to share; but as our attitudes and awareness grow and shift, so do the definitions of that dream. It's time to redefine, to clarify what we're after. It's time to let go of...

Manifesto follow-up: three designs

So what does this new dwelling look like? Well, of course, it could take endless form; but to provide a prototypical starting point, I created a series of designs using American housing typologies. By starting with the familiar, we can appreciate both the timeless and...

Heating and cooling the Passive House

One of the main qualities of a Passive House building is that the mechanical loads are so reduced that you only need a tiny system for heating and cooling.  Even for this relatively big house, there is no conventional furnace/AC small enough that it wouldn't be way...

Ventilation for the Passive House

One of the qualities of a Passive House is that the construction is nearly airtight., so to allow the house to "breathe" we use an energy-recovery-ventilator (or heat-recovery ventilator).  Yes, houses need to "breathe", or more accurately, people inside houses need...

Interior renderings

Here is some eye candy. It's fun to think of these while standing in the house now (with 10 tradesmen working hard all around).  You'll see a number of light coves--we're using T5 fluorescent strip lights, which are extremely efficient; plus the indirect uplight...
