This project of ours has 8” of insulation (R-40) over the slab on grade. That’s 4 times the requirement in NY! A massive amount of heat can be lost through the slab so it’s just as important to insulate as the walls (Which will also get 6-8” of the same insulation) . Plus, the insulation helps prevent condensation. ~Alex ~Observations from a Jr. Architect

In progress: large format porcelain tile application in this new master bathroom as part of a very minimalist approach to design. The shower area shown here is directly across a tall and wide window looking out to a private and beautifully landscaped backyard. We let nature’s intricacies complement the simplicity of this interior finish. #porcelaintile #minimalistdesign #modernbath

Spring rain helps the summer flowers! However, yesterday’s storm might have washed all the flowers away…While you’re repairing your garden, think of bolstering your number of indoor plants. Plants help absorb off-gassing and trace amounts of VOCs (volatile organic compound) that are sometimes found in construction materials. They also help people breathe better. Nowadays, many conscientious architects and builders are aware of this and can optimize Indoor Air Quality, but for chemically sensitive people and those who can’t build from scratch, the solution could be as simple as a few new palm plants. ~Alex

Planning a new home or addition? Consider insulating concrete forms wherever you plan to add living space. ICFs can improve the comfort of your below-grade spaces and provide savings on a job by combining concrete formwork and insulation into a single step.

Garage and master suite addition to a shed roof mid century modern.

Here in N.E, Winter has abruptly ended and Spring is here! Many people have been looking to expand their houses with small additions and bump-outs. But don’t forget about that space above the garage! It’s easy to dismiss that square footage as storage but some of my favorite spaces are cozy areas above the garage. They’re perfect for apartments, in-law suites, kid play areas, or a place to escape. ~Alex ~Observations from a Jr. Architect
