The new 275m2 building will partly sit on the existing car park outside the Grade II-listed church - the firm's home for the last 17 years - and will create much-needed office space for the practice's 120-strong workforce.
Practice director Geoff Halliwell said: 'The church was opened in 1906, and Bond Bryan refurbished it in 1990 as our office studio. But with the practice winning a series of major new contracts nationally over the past few years we need more space for our growing team.
'We are employing the same sustainability principles we use when working for clients. This means, for example, the 'green' roof will be covered in sedum, the design provides natural light and ventilation for the best working environment and minimises energy use.'
He added: 'We have worked very closely with those who live nearby in order to achieve a planning proposal that meets the needs of a rapidly growing practice while ensuring we remain a good neighbour and are able to continue working in this mainly residential area of Sheffield.'
The scheme is due to start on site in April, with completion planned for December 2007.
