Tudors or craftsman home styles offer a lot

About once a year, we discuss the importance of understanding the history, style and architecture of your home. This knowledge is crucial when designing an addition or renovation.

The popularity of several predominant home styles has endured over the past few centuries in the United States. They include the fairy-tale Tudor revival, classic craftsman bungalow and the charming Cape Cod cottage. In addition, we Americans have added a style of our own in the last century the California ranch.

With each style comes unique renovation challenges and opportunities. The first thing to analyze when considering an exterior home remodeling project is the style of your house. Not every home was designed in a distinct style, and homes can actually have conflicting elements of several styles. Nevertheless, try to determine the predominant style of your home, as the next decision will be whether to revive and enhance it or to change it into something else.

We hope the next few columns can help you determine the predominant style of your home and the challenges you may face renovating that style.

Tudor revival

In their purest form, Tudors feel like miniature castles with towers, dormers and steeply pitched roofs. The windows are tall and narrow, with multi-paned glass and the massive chimneys are commonly crowned with decorative chimney pots.

The style is accented on the outside with decorative half-timbering, patterned brickwork, stucco or stone.

Inside you'll find stained oak paneling and fine interior woodwork. The doorways are often arched and the ceilings accented with exposed structural beams.

The Tudor challenge: If you have a historical Tudor, you will be faced with inevitable challenges in remodeling while maintaining this distinctive style. One of the most prominent features of a Tudor is the steep roof. When renovating, that roof massing has to be accounted for in the new design or the style will be compromised.

On the other hand, if you have always dreamed of living in a Tudor house and want to remodel your existing home into this style, be prepared for a major investment. Remember that the steep roof design element is critical to the style, so most modern homes would need a new, steeper roof added in order to morph into a Tudor style. Adding gridded windows and faux half timbers to your stucco house will not cut the mustard if your roof has a 4:12 pitch.

Craftsman bungalow

The craftsman bungalow is an easy-to-spot style. You'll recognize these homes by their dominating roofs and single-story appearance. If there is a second story, it is subtly tucked into the roof line.

The craftsman bungalow is low to the ground and centered. They were designed with lots of windows for light and ventilation. You can't miss the pronounced front porch, often with tapered wood columns resting on sturdy masonry bases. You'll also sometimes see exposed roof rafters and open eaves. Broad eaves and overhangs are another hallmark of the craftsman style.

Common exterior materials include brick, stone, shingles and stucco.

Inside the craftsman bungalow you'll find a family-oriented living space with a craftsman's attention. You will often find crown moldings, high baseboards, paneled wainscoting and wood floors, as well as a tiled hearth with a brick fireplace, built-in bookshelves and beamed ceilings.

Interior rooms are arranged to encourage family togetherness, with public spaces open to each other, somewhat reminiscent of today's popular great-room style. Craftsman bungalows may also include intimate built-in seating areas known as inglenooks.

The craftsman challenge: True craftsman bungalows were well-designed and well-built and therefore tend to have faithful owners who love their beautiful, functional homes.

That means they do not change hands often, so they may need updating when a new owner moves in. If you are lucky enough to have a bungalow or are looking at purchasing one, plan your renovations carefully so you maintain its innate interior functionality and preserve its exterior sense of being centered, solid and enduring.

All things craftsman seem to be very popular these days. Many people come to us requesting this style. However, as with the Tudor style, the look depends a lot on the basic massing of the home. Those broad overhangs are critical, and eaves are not something that can just be magically extended. If you were to continue the pitch of your existing roof to provide 3-foot overhangs, the edge of the roof will drop to an unacceptable height perhaps so low that it will interfere with the existing windows. Therefore, the entire roof needs to be lifted and repitched or, in other words, rebuilt.

Be careful about adding bits and pieces of an inappropriate style to your home. While you may find a beautiful craftsman front door, adding it to your home may not be advantageous to the overall look and style. It is easier to create a craftsman style on the interior of your home than on the exterior.

In our next column, we will discuss the characteristics of Cape Cod style homes and California ranches.
Its toxic: New study says blue light from tech devices can speed up blindness

It turns out checking Twitter or Facebook before bed is bad for your health.

A new study from the University of Toledo found that blue light from digital devices can transform molecules in your eyes retina into cell killers.

That process can lead to age-related macular degeneration, which is a leading cause of blindness in the United States, according to the researchs extract.

Blue light is a common issue for many modern Americans. Blue light is emitted from screens, most notably at night, causing sleep loss, eye strain and a number of other issues.

Dr. Ajith Karunarathne, assistant professor in the UT Department of Chemistry and Biochemistry, said our constant exposure to blue light cant be blocked by the lens or cornea.

"It's no secret that blue light harms our vision by damaging the eye's retina. Our experiments explain how this happens, and we hope this leads to therapies that slow macular degeneration, such as a new kind of eye drop, he said.

Macular degeneration is an incurable eye disease that often affects those in their 50s or 60s. It occurs after the death of photoreceptor cells in the retina. Those cells need retinal to sense light and help signal the brain.

The research team found blue light exposure created poisonous chemical molecules that killed photoreceptor cells

"It's toxic. If you shine blue light on retinal, the retinal kills photoreceptor cells as the signaling molecule on the membrane dissolves," said Kasun Ratnayake, a Ph.D. student researcher working in Karunarathne's cellular photo chemistry group. "Photoreceptor cells do not regenerate in the eye. When they're dead, they're dead for good."

However, the researchers found a molecule called alpha-tocopherol, which comes from Vitamin E, can help prevent cell death, according to Futurism.

The researchers plan to review how light from TVs, cellphones and tablet screens affect the eyes as well.

"If you look at the amount of light coming out of your cellphone, it's not great but it seems tolerable," said Dr. John Payton, visiting assistant professor in the UT Department of Chemistry and Biochemistry. "Some cellphone companies are adding blue-light filters to the screens, and I think that is a good idea."

Indeed, Apple released a Night Shift mode two years ago to help quell blue lights strain on the eyes, according to The Verge. The screen will dim into a warmer, orange light that will cause less stress on the eyes.
