Homes in Severn

Severn has an unusually large share of townhouses and other attached houses: 31% of its 22,332 homes, beside 50% detached houses and 15% apartments.

Much of Severn is new: 46% of homes were built 2000 or later, and only 25% before 1980. The median home dates from 1997. Owners live in 71% of homes.

In nearby Glen Burnie, 5 miles away, 64% of homes were built before 1980, so Severn's windows are on the whole newer. Nationally, Severn's homes are newer than those in 81% of the 881 US cities we have census figures for.

Townhouses

31% of homes share a wall with the next one. Their front windows face the street side by side with the neighbours', so many owners pick a louver size and a white or off-white finish that sit well beside the houses on either side. Bay windows on townhouses usually need a separate panel set for each face.

Shallow openings

46% of homes were built in 2000 or later. Newer windows are often set close to the room side of the wall, and handles, cranks and alarm sensors stick out into the space a louver swings through. Measure the depth to the glass and to anything that sticks out; the designer checks it against the louver size you pick.

Choosing a louver size

Rounded drywall corners

75% of homes here were built from 1980 on, and many houses of that era have rounded ("bullnose") drywall corners around the windows instead of square returns. A shutter can't sit flat against a curve: choose an outside mount with a frame that clears the corner, or an inside mount if the flat part of the opening is deep enough for your louvers.

How to measure

Bought to stay

Owners live in 71% of homes, and shutters are usually bought to stay with the house. Poplar takes paint well, so they can be repainted years from now if you change a room's colours. Keep your order list: it records every size if you add a room later.

Why poplar

A whole house in Severn

The most common home in Severn has three bedrooms: 40% of homes. Large houses are common too: 36% have four bedrooms or more. The median home has 6.4 rooms.

Detached houses are the most common kind of home here. Across the US, the middle home among detached houses has 10 to 15 windows (EIA, 2020). Shuttering that many windows at a typical bedroom-window size comes to roughly $3,200 to $6,000. For scale, that's about 1% of the median home value here, $479,200 (owners’ estimates, 2020–2024).

Homes here are larger than in 84% of the 881 US cities we have figures for, so a whole-house order runs to more windows than most.

Young children at home

6.7% of people in Severn are under five, more than in 83% of the 881 US cities we have figures for. Shutters have no cords or chains at all: the louvers tilt with a rod or by hand, so there's nothing to hang within a child's reach. US rules for cords on custom blinds and shades are still being rewritten; ours never had any.

Pricing a whole house at once

36% of homes here have four bedrooms or more. For a house that size, list every window in one go: type or paste the sizes, or upload them as a spreadsheet saved as CSV, and the designer prices each window and the total.

Working from home

17% of workers here worked from home in the 2020–2024 survey years, more than in 64% of the 881 US cities we have figures for. Glare on a screen comes from direct sun and bright sky behind or beside it. Louvers tilted up throw daylight at the ceiling instead, so the room stays bright and the screen stays readable; wider louvers give the clearest view when you open them.

Humid summers

Hot days and 48.2 inches of precipitation make for heavy summer air. Wood swells when it's humid, so give kitchens, bathrooms and laundry rooms some air: run the fan after a shower and tilt the louvers open so steam doesn't sit behind them.

Why poplar

Cold winters

With 93 freezing nights a year, warm room air meets cold glass for months. Shutters closed tight overnight hold that air against the window, so condensation can collect on the sill: tilt the louvers open in the morning, and wipe the sill on windows that often run wet.

Why poplar
