پس از تثبیت جانمایی‌های اصلی، ریزفضاهای لازم به تناسب عملکرد هریک از فضاها تعریف شدند. در سالن غذاخوری، با توجه به اینکه عملیات پخت در آن انجام نمی‌شد، مساحت لازم برای آشپزخانه‌ای با امکانات مختصر جهت آماده‌سازی غذا، شامل اتاق ظرف‌شویی، کانتر گرم، یخچال و باکس‌های ذخیره، برنامه‌ریزی شد. در نمازخانه نیز برای تکمیل امکانات این فضا، فضای کفش‌کن به‌صورت مجزا، کمدهای پنهان برای نگهداری وسایل لازم، و محل قرارگیری تجهیزات صوتی تعریف شد. درب‌های برقی نیز که از گذشته در مجموعه وجود داشتند، برای کاهش هزینه‌ها، مجددا در طراحی ورودی سالن غذاخوری و سرویس بهداشتی مورد است.فاده قرار گرفتند.

In the status quo, the prayer hall was located on north-end, and the dining hall was located on south-end. Considering the direction of Qibla and the access to prayer hall, resulted in a long undesirable corridor which occupied a large area. Also, the positioning of the dining hall on south-end which resulted in unfavorable views to the roof and mechanical facilities, and its distance from the dishwasher room also needed to be redesigned. Requirements such as two main accesses from the north and south to the roof, maintaining the required area for each space according to the design specifications, and access to the utility room, also imposed their restrictions. Therefore, the first step in design was the rearrangement of spaces: the spatial organization. By switching the locations of the prayer hall and dining hall, more suitable access to the prayer hall, and a more beautiful view towards the northern mountains of Tehran, was achieved in the dining hall. The entrance lobby, located next to the elevator, provided access to other spaces, with a more appropriate geometry, and a more favorable area. In the end, due to the spatial limitations, the toilet was placed in the middle of these two spaces, and adjacent to the prayer hall.

There are different types of wall coverings in terms of application and constituent materials, such as: wooden wall coverings, leather and stone wall coverings, and D wall coverings, as well as types of ceramic tiles, all of which can be used as wall coverings according to your taste. According to the taste and design that you have considered, you can give a special and different effect to the interior of your building and enjoy the renovation of your building.

The materials, their color and texture in each space, was selected according to the nature of the space. Our goal in designing the prayer hall was simplicity and purity in all its components, so that the main focus is on the direction of the Qibla and the position of the Mihrab. The combination of blue and white in the prayer hall, provides a relaxing environment for prayers, during contemplation and daily worship. Also, the separation of this two colors with its pleasant contrast in the vicinity of the Mihrab, and the use of rhythm and repetitive geometric pattern caused more focus on it. The extension of this pattern in the openings, and the planting of shrubs in the background, created a more lively atmosphere. The design of north wall encircling the Mihrab was completed with prominent verses, which done by masonry, in white color, and with a uniform texture. In the dining hall, deployment of wood and its combination on a white and gray background, has given a special warmth to the space, and has created an intimate environment for a friendly chat while eating. Finally, a green wall including shrubs and vines, was integrated continuously, with lattice scaffolding to a height of . meters, in the exterior of the building, and on the roof, to improve the view in all the walls with opening.

After the rearrangement, the necessary sub-spaces were defined according to the function of space. In the dining hall which there the food is served and not prepared, a small pantry was planned with small facilities for preparing food, a dishwasher, a hot counter, a refrigerator, and storage boxes. In the prayer hall, the shoe rack is placed separately, storage are removed from sight, and audio devices are considered to complete the requirement of this space. The previously existed automatic sliding doors was also reused in the design of the entrance to the dining room and bathroom, to reduce costs.
