Five Tips to Make Your House Look Greener
There are plenty of ways to make your house look greener. It doesn't matter how many people reside in your home. It doesn't even matter what is the size of your home. What matters is how your house looks and how it affects you and others residing in it.
It is very necessary to make your house look greener because it has a direct impact on your health. If you keep your house greener, you will get rid of many dangerous diseases. Here are some ways to keep it greener.
1. Good and reliable Interior
Indoor material, like windows, doors, cupboards, etc. must be of good quality. These things play an important role to clean the house. Doors and cupboards must be of high quality wood. Aluminium windows must be used. You must use high-quality paints for walls, doors, windows and cupboards.
2. Using wider windows and doors for ventilation.
Oxygen is a necessary element to enable you to live alive. For healthy life, windows and doors must be wide and usually be kept open at least for 15 hours a day, as ventilation of air makes you fresh and healthy.
3. Placing plants especially flowers at various places
No one wants an empty house, and plants definitely play a refreshing role. First, the plants provide you with oxygen necessary for survival. Second, plants and especially flowers spread heart-attracting fragrance. All unhealthy odors are eradicated from your home and you feel fresh whenever you are inside it. Flowers also make your home interior look more appealing.
4. Disposing off wastes away from home regularly
It's very important to throw away household wastes far from your house every day. When wastes are kept untouched for many days, they attract bacteria and viruses. Flies and mosquitoes also start gathering and increasing at such places. As a result, diseases are caused.
5. Using anti-bacterial materials for washing floors and contents
Usually unclean fans, floors and walls breed bacteria and viruses, which are then carried by flies and mosquitoes. These carriers then infect the humans by contact through contaminated food or direct attacks on human body. It's always recommended to use anti-bacterial or anti-viral cleaners for fans, floors, walls, laptops, and TVs.

Amphibious Architecture: Flood-Proof Home Designs
Instead of trying to beat back the rising flood, innovative amphibious buildings can adapt to the rising flood. These buildings are ready for whatever Mother Nature might throw at them– even 10-foot floodwaters. Let's take a look at just two of them.
The UK's First Amphibious House
The UK's first amphibious house is located on the Thames River. And the first amphibious building in Britain will be completed soon. Baca Architects designed this home for a couple who wanted to live on a flood-prone island, an island easy to be attacked by floods, in the Thames River. This building is equipped with a terraced landscape. And this terraced landscape acts as an early warning system when the waters are rising. The terraces will be filled with water before the ‘wet dock’ under the house does, and then the home itself will slowly rise to stay above the water.
Solar Powered Floating School in Nigeria
Residents of Makoko in Nigeria have been building houses on stilts for generations. People there go from one house to another by canoe. As sea levels are rising, officials threaten to tear down the entire community. If these houses are tore down, 250,000 people will be homeless and have to look for a new place to live. Architects found a solution in floating structures with improved sanitation conditions. The first completed example is a three-storey solar-powered school.
