St Kilda Cottage House

Jost Architects as Architects

We took a classic weatherboard cottage located in St Kilda with a council Heritage Overlay and removed the previous 1980s extension to the rear. The brief was to add a master bedroom, ensuite, WIR and an east facing deck on the upper level, refurbish the existing area of the house and fill in a small wedge-shaped area of land on the existing area. Planning constraints meant that careful consideration was given to how the upper level addition sat within the streetscape. The existing ground floor footprint was used without needing to push further back into the rear of the small site.


This is where things got interesting. Because the site tapered, becoming narrower to the rear, and the proposed building was intended to utilise this valuable unused space, it meant that the shape of the building also tapered. The geometry applied ensured that the upper level façades presented symmetrically to each ends of the property. A couple of the builder’s carpenters who set out the framing had minor existential crises. Ironically, all this was very carefully worked out so no one would actually notice, a bit like a scene from Alice in Wonderland.


We deliberately made the new additions visibly contemporary in contrast to the existing dwelling, but did not move too far away from the original. The galvanised custom orb cladding wraps up one side, over and down on the other, intersecting with the weatherboard cladding. Both familiar materials found on the classic Victorian workers cottages found in this part of St Kilda.


The screened internal space is visually permeable, becoming an active and changing aspect of the dwelling depending on the time of day, conditions and lighting.


The internal planning was extremely important as there was no room to build further back to increase the internal area of the house without detriment to the very small rear yard. Some of these methods include the introduction of a booth seat to the front of the kitchen island bench for dining and freeing up living space. Stackable bi-fold doors open up to include the court yard as part of this space, when the weather is good. At the top of the stairs, one side is a door to the roof deck and to the other, past the concealed laundry in the hallway is the master bedroom. Off the bedroom is the rear deck, which is sheltered by the operable aluminium screen. This provides privacy and protection from the western summer sun. Returning back to the east, is the walk-in-robe leading into the ensuite and back out to the roof deck. Using room to room movement in a circular plan reduces wasted corridor space, creating a more comfortable and liveable area. It also allows excellent cross ventilation and natural light to all of the upper rooms.


The existing rooms were refurbished, retaining their original features and trims with new contemporary fixtures and fittings that are aesthetically complimentary.


The honest interior finishes and the careful detail employed are clean, precise and practical. This aspect of the design was also very important to the client, and delivered a combination of sensibility and functionality that won’t date.


The result is a unique and subtle addition that compliments the existing heritage dwelling and delivers a peaceful, modern home!
