ROOF options on all sides of the building . A new road , Park Lane , was also created with wide boulevards to provide pedestrian access to the building . There was an existing low rise office development on site that was demolished to make way for the new building , and as services were already in place the site itself did not present any challenges .

GROUND FLOOR
Brief The brief to the design team was to create a building with office space that was highly flexible ; accommodating tenants with varying space requirements . During the initial development process , 1 Park Lane ’ s anchor tenant , Bidvest Bank , were intensively consulted on their requirements and , consequently , floor plates from reception to the 4th floor were developed to suit the bank ’ s specific requirements . The building was designed without an underground basement parking structure and therefore has nine floors of above-ground parking , with 11 floors of office space catering for 1,000 parking bays .
The Building From a tenancy perspective the design team wanted to take advantage of the building ’ s height and maximise the panoramic views to the north and south over Sandton . These views are completely expansive from floor to ceiling , with no breaks in the glazing , including spandrels and cills .
The rest of the envelope is clad in a mixture of A2 rated aluminium composite panel ( ACP ) and unitised double glazing in one system . The chosen system lent itself to being responsive to conditions on site and was required in terms of energy efficiency , HVAC design and ventilation .
Using the latest technology to identify hot spots , a very specific design pattern was assigned to the ACP in order to meet requirements from a heating and cooling perspective as a certain percentage of the façade facing west and east was required to be solid to account for temperature regulation within the building . Without the temperature regulation integrated into the building ’ s envelope , the HVAC system would not be able to cool the interior space down sufficiently . A unitised façade system was used to maximise the structural requirements of the design whilst containing costs .
The challenging aspect of this façade design was to source a glass that looked exactly the same in both single and double glazed versions , ensuring a completely seamless look to the façade throughout . Extensive research was carried out into the glass options available until a suitable product was found . Planting has also been incorporated into the façade and the roof to disguise plant machinery that could not be integrated further into
