The two tombs TT284 and TT285 in the area of ​​Dra' Abu al-Naga have unique architectural type comparing to the rest of the cemetery tombs. Yet, some previous studies classified these two tombs as the T-shape,  assuming  that the rest of the tomb's elements were added elements due to reusing the tomb. Based on that misclassification, the dating of the two tombs and their architectural type assumed to be different to their construction date.  Therefore, this study is an attempt to disclose both tombs uniqueness architectural type and explain the reasons for its construction. Another contribution for the current study is to discuss the reasons why previous studies had assumed that the two tombs had been reused. Our study shows that this conclusion is as inaccurate.
