The Indo-Islamic architecture manifested the aesthetic heritage of the new sultans that includes both religious and secular structures. While indigenous architecture is Trabeate i.e. the space is spanned by mean of beams laid horizontally; the Islamic form is Arcuate, whereby arches are used to bridge a space. The dome is the prominent feature of the mosque in contrast to the Sikhar of Hindu temples.
1. Arch and dome method which dispensed with the need for large number of pillars to support the roof and enabled the construction of large halls with a clear view.
2. Use of superior mortar to hold the stones.
3. Use of slab and beam method.
4. Decorative exuberance, such as use of geometrical shapes, calligraphy, inspirational art etc.
5. Synthesise of indigenous motif such as ball motif, lotus etc.

3. Tomb of Balban
It is first example of true arch and is located at the archaeological park in Mehrauli.
It contains a dome, which for the first time was built on correct scientific lines and also has arches of very pleasing proportions.
5. Alauddin Khilji built new fort and imperial township of SIRI. In siri, he built the Mahal Hazar Satun, the palace of thousand pillars, Hauz-i-illahi, a water tank and the Jamait Khana mosque at the Dargah of nizamuddin Auliya.
6. Alai Darwaza

It is located in the Qutub Complex, which is located near the Mehrauli Archaeological Park. It was built by Ala-ud-din Khilji, as a college for the education on Islamic scriptures and theology that consists of rooms and halls built around a quadrangular court.
The Palace cum Fortress Complex of Tughlaqabad was constructed by Ghiyasuddin Tughlaq. Mohammed-bin-Tughlaq built the Tomb of Ghiyasuddin Tughlaq on a high platform which marks a new trend in architecture for imposing skyline. He also built Jahanpanah, one of the cities of Dilhi. Firoz Shah built Hauz Khas, a pleasure resort and also built Firoz Shah Kotla fort. The Tughlaqs rulers started building the tombs on an elevated platform. They combine the principles of arch and done with Islam and as are evident in Firoz Shah Tughlaq’s construction of Hauz Khas.
