In its final stage before its destruction of the temple was an impressive structure. Additional facilities were located on a raised platform, the three Chedis, which are today the only buildings which have been restored. From all other the foundations are still preserved.
The chedi is built in the classic, Ceylonese design that is reminiscent of a bell. In every direction small chapels are recognized, lead to which steep stairs. The roofs of the chapels are in turn topped with a miniature Chedi. Each of the three chedi is on the eastern side assigned a Mondop where possibly footprints Buddhas were.
The terrace of the Chedi with Mondop were surrounded by a cloister (Phra Rabieng), in each case a hall was built in the west and in the east, an arrangement as can be seen in many temples in the country today. The building in the West actually consisted of four individual viharn, which were arranged in a cross shape to a Mondop around. The building to the east was the viharn Luang, the biggest building of the temple. In it stood the statue of Phra Si Sanphet Phuttha, which gave the name to the temple.
Symmetrically around the viharn Luang were grouped four other halls. North was a viharn which was a bit smaller than the viharn Luang, yet large enough to accommodate the more than 10 m high statue of Phra Phuttha Lokanat. East front was the Phra Chom Thong Tinang Throne Hall.
Symmetrically, stood south of the viharn of Luang viharn Pa Le Lei, in which probably was a seated Buddha statue. East front of the Phra Ubosot was.
To the entire complex there drew a high perimeter wall, four gate passages in the four directions offered access to the temple. Inside along the wall were alternately small Chedis and low pavilions (Sala). Of these small chedi are still some survived.
