Avoid dark corridors or hallways as these require energy to light and provide a dismal interior to the home. These areas are often hidden in display homes, where they install ample electric lighting to provide a warm fuzzy glow to the home.
If you have wide corridors make sure they are wide enough to include sideboards or built-in storage space so the space doesnt go unused. On the other hand, try to leave areas where two people can pass easily, even if they are carrying loads such as suitcase or washing basket.
Planning books should provide you with dimensions that are suitable for corridors, depending on their use.
Vistas
Your home should be designed to take advantage of potential views from family, living or dining areas if possible.
It is important that your family and kitchen areas have good views to the outside entertainment areas. This allows parents to watch over the safety of their youngsters when they are either playing outside or in the pool.
The orientation of these views is very important!!!
If a view is to the west;
Be very careful about how much glazing is provided. Even in winter you can gain enough heat to make it uncomfortable to sit inside.
Vertical shading or adjustable shading such as awnings may be required.
Try to plant trees or shrubs which will offer enough shade whilst allowing the view to be maintained.
Thermal mass on the western elevation of the house will stop the heat in the afternoon, but as the heat travels through into the house you need a way to get rid of it.
If a view is to the east;
Glazing which allows morning sun in will also allow morning heat in.
In winter the morning heat can be nice so think about deciduous trees which will protect you from the morning summer sun.
Like the western sun fixed shading needs to be vertical to stop sun penetration.
Look at different types of glass, such as low-e glass, which will help to control heat gain.
If the view is to the south;
Keep in mind you will almost never get any direct sunlight.
The south is good for letting in ambient light all year round, but poorly insulated windows will lose heat in winter.
Use heavy curtains or blinds to keep in heat at night.
If there is a prevalent breeze which comes in from the south this can be harnessed to cool the house if you have operable windows.
Make sure the windows are well sealed to avoid draughts in winter.
If the view is to the north;
PERFECT!
Try to increase your glazing to let in winter sun.
Have reasonable eaves to protect the glass from direct summer sun.
If there is an opportunity to have some thermal mass, this can be used to passively heat your home.
