The need for two master bedrooms in a home may not be for the reasons you think.
The polite habit of giving up the best bedroom for your house guests and retreating elsewhere would not be needed. If there was a second master bedroom with its own bath, you the home owner would not have to vacate and retreat to the cramped back bedroom. Because that kind of swanky comfortable could quickly wear out the welcome of the folks from away who decide to stay on and on longer.
They say company is like fish. It can start to smell after a few days. No matter which side of the family the house guests are related to in the home away from home, we've got company experience.
A second master bedroom is catching on in home building house plans for lots of reasons.
The King and Queen in the home might have health problems that interfere with a good night's sleep. You know how grumpy you and I are if the rise and shine is after a night of tossing and turning. Counting sheep pretty much all night long.
If Dad snores or likes to read detective novels long into the night, if Mom is a night owl and watching murder mysteries while her mate is trying to saw logs causes a delay for the visit from the sandman. Or the queen of the house sadly develops a hiatal hernia that means the bottom footer of the bed has to be jacked up like the back end of a 1960's muscle car, the two situations clash. No easy remed sharing the same bed or setting up twins. It can cause discomfort for both of the home owners. So the remedy could be a pair of master bedrooms. No one person gets the penthouse quarters in the coin toss, both do. In vacation homes, all the brothers and sisters want equal digs. Mr. Carpenter, construct more super sized master bedrooms please.
Elderly parents moving into to live under the same roof line need larger than average bedrooms.
They have deserved the right to have a special master bedroom and not be crammed into the back bedroom with no window, missing a closet and located pretty much as far away from the nearest bathroom as possible. That won't work with a walker or poor eye sight in the middle of the night one hundred yard dash or crawl. Some have breathing machines to place in the already tight for space bedroom area. Expand the walls please. Don't fence me in.
The senior citizens should get a master bedroom just as plush as the home owner because they are helping to swing the house payment by subsidizing living expenses. Or the Golden Girls set up in Florida all should have equally nice appointed and just as large master bedroom retreats.
