The Harry Seidler & Associates offices and top-floor apartment were developed in three stages. The first building (no 2 Glen Street) was completed in 1973. It is an 11 m clear span office building of prestressed expressively profiled T-beams with vertical exterior concrete sun blades.

The first addition (no 2A Glen Street), completed in 1988, extends the offices on the lower floors and adds a penthouse apartment on top. Entry to the penthouse is into a space two storeys high, with a presentation theatre and facilities for entertaining. A half-elliptical Indian granite dining table allows guests to sit at the curved side of the table so that they can see the splendid water view; the hosts sit on the opposite side, facing their guests. A curved stair leads to the upper floor lounge, study and master bedroom suite. Within the straight outline plan, flowing curves enrich the open interior. Only the artworks (by Albers, Stella, Lichtenstein, Mais, Perry and Noland) are colourful in contrast to the neutral grey, white and black interior.

Design/Completion: 1973, 1988

Tour experience

The offices of Seidler & Associates and adjoining penthouse at Milsons Point are testament to Harry and Penelope Seidler's unwavering attention to detail in the design of spaces for working and living.

From the original office furniture in the workplace to bespoke cabinetry in the home, art is integrated into all aspects of life. Join Polly Seidler on a tour of their offices, and walk through the connecting door from the meeting room into the stunning penthouse apartment, now used as guest accommodation for visiting artists and architects. Tour will also explain & view neighbouring Harry’s Park completed in 2011. Strictly no photography allowed.
