The many examples of traditional Bhutanese architecture that we see were all built in this way. Architectural styles differ from place to place and from different periods in time.
The differences in style are due to:

Once the building is completed, artists often embellish it by painting different auspicious motifs. The selection of the site for any building, as well as the different steps of the construction, are guided by the astrologer's calculations and always followed by rituals. For religious buildings, the configuration of the site and good omens are considered very important.
Within seven months, several important structures were completed. Among them was the Taktshang Pelphug which houses three lhakhangs: the Phurpai Dubkhang on the ground floor where Guru Rinpoche meditated; the Guru Sungjoen Lhakhang, situated on the first floor of the building and named after the image of the Guru which is believed to have spoken; and the Guru Tshen Gyed Lhakhang, on the top floor, named after the eight manifestations of Guru Rinpoche.
A fire proof structure (methub) will be constructed in the Chorten Lhakhang to safeguard the sacred nangtens from fire and theft.
