task redesign dental clinic layout inside existing floor plan use the attached drawing as a fixed shell keep all exterior boundaries and structural walls unchanged redesign internal partitions only existing openings as shown in the reference plan exterior windows the plan has three windows on the curved facade of the round room left curved window middle curved window this should become the new main entrance right curved window there are also two windows on the long straight exterior facade the facade intended for the treatment room left window right window these two windows must remain and serve the treatment room exterior door changes convert the middle window in the curved facade into the only main entrance door convert the existing current entrance door into a window there must be only one exterior entrance in the project required zoning layout 1 reception use the circular front room as reception and waiting area main entrance enters directly into reception reception remains in the round room keep curved facade and side windows 2 main treatment room create one large treatment room for 2 dental units positioned along the facade with the two straight wall windows requirements occupy the full window side use both windows for natural light approx 21 28 m this should be the main room of the clinic 3 support rooms place all support rooms in a row along the opposite interior wall opposite the treatment room sequence wc sterilization compressor room staff room all of these should be aligned along one wall only corridor and internal doors important corridor create one central corridor running between treatment room on one side support rooms on the opposite side the corridor should connect reception treatment room all support rooms this corridor should function as the main internal circulation spine internal doors arrange internal doors as follows from reception one internal door from reception into the corridor from corridor provide separate doors from corridor into treatment room wc sterilization compressor room staff room treatment room access main access to treatment room should be from corridor optional direct door between treatment room and sterilization is acceptable and preferred spatial logic must follow exactly layout should read as curved front zone reception main entrance middle circulation band corridor window facade side large treatment room opposite wall side linear row of support rooms this should be a linear plan not a central or scattered composition constraints do not change exterior perimeter move load bearing walls alter facade geometry add a second entrance place support rooms by the two treatment room windows distribute support rooms around the plan modify internal partitions only drawing style use exactly the same style as the reference monochrome architectural drafting same line weights same hatches same furniture equipment symbol style goal functional two chair dental clinic within the existing shell preserving all structural boundaries
