The idea from LIGHT ON 2 SIDES, comes from one of CA’s patterns.

He explains it like this:

Sssssssssssxxxxxxxxxx

And once I appreciate this fact… it gives me a vocabulary to say why I hate townhouses…. and most hotel rooms….a door on one side and a window straight ahead.

The beautiful town houses of Back Bay, Boston, worked this problem a bit, by having huge circular bay windows… acting as a powerful magnet to BE in, relieving the tension of the closed off space in the foreground.

What free standing house has the least windows on 2 sides?

Massive square or rectangular houses.  These provide only 4 rooms per floor, with correct lighting.

Ironically, small 1000-1500sf houses, of this shape, have so few rooms, that the proportion of well-lit rooms is high.

What kind of design footprint has the most rooms with light on 2 sides?

….answer… one build like a pinwheel…

A central core area, and 4 wings jutting out…

This house is said to be so will built, no one ever wanted to sell it.

Ok that is extreme, in a small SITE area, sometimes we cannot have 4 wings…but you can have bays or protrusions all around…that really relieves the pressure of enough light all thru out a house, no matter how squat or huge the footprint.!

See how this old brick house used protrusions to correct the light?
