Saturn and Venus are in my 8th house in sign 8 (Scorpio); can I open a West door?
Saturn in the 8th is not bad. Here Saturn sits in a sign of Mars, and Mars with Saturn forbids the South, but the West door can be opened. Send the kundli for a closer look before opening it.

In my chart no planet is exalted or debilitated. How should I understand this for choosing a door?
There is nothing to read into it; not everyone has exalted or debilitated planets, and it is neither good nor bad. In such cases the door is chosen towards the direction in which the benefic planets sit, which was taken up in the evening astro-vastu class.
In the example of the Sun in the 8th house, would an East entrance have suited if the Sun had been retrograde?
Possibly, but then its degree and the aspects on it, such as a benefic planet's aspect, would have to be checked. A house is built only once, so such a risk should not be taken. Retrograde (vakri) planets are taught later in the course.
Is choosing the door related to astrology?
Yes. With the person's astrology as the base, the door is chosen according to whom it will suit. The class covers three ways, by rashi, by exalted and debilitated planets in the birth chart, and by mulank, and the birth chart carries the most weight.
My Jupiter is exalted and my door is on N6-N7, towards the North-East, yet we have had no problems. Why?
The Ishaan (North-East) corner belongs to Jupiter, so people whose Jupiter is exalted can keep their door there. This shows how the birth chart decides which door suits a person.
My house entry is in the SSW and my 10th house has Sun, Mercury, Moon and Ketu with an exalted Venus; can I move the entry to the South-East?
If you open the South, open it in the good South pada (S4 as heard), and if you open the West, in the good West pada (W4 as heard). The present South-West entry should be corrected with door power.
My new flat's entry is on N4, but Mercury sits in the 8th house of my Mesh lagna chart, though not debilitated. Will using this door activate the 8th house?
Such a case has to be judged from the birth chart, so it was taken up as a special case study in the evening astro-vastu class. For this analysis only the lagna chart is used, not the navamsha, so only the lagna chart needs to be sent.
