An All-Timber, Small Footprint Addition To A Simple Weatherboard Cottage

North King by Ben Callery Architects is a newly-altered weatherboard cottage in Northcote, Melbourne with a generosity that belies its size.

Utilising a timber ‘king post truss’ that spans the full width of the space, the heritage home’s soaring new addition replaces a former lean-to, to invite incredible light and warmth into the interiors.

The use of an all-timber structure facilitates a sustainable home, that is low in embodied energy and supported by solar power generated on site.

North King by Ben Callery Architects in Northcote, Melbourne has been newly-extended with an efficient, all-timber addition.

Utilising a king post truss, the heritage home’s soaring new addition replaces a former lean-to to invite incredible light and warmth into the interiors.

Outside, a new deck serves as an extension of the living area under a pergola ready to be engulfed in deciduous vines.

The addition utilises an all-timber structure including king post truss that spans 7.3 metres and allows perpendicular sliding doors to open.

The dining table seating is built in to maximise space.

Green accents across painted surfaces tie the entire home together.

‘The truss is the really unique element of this project, spanning the full width of the building and creating this great opening, with an engineered solution handmade from natural materials,’ says Ben.

‘We engaged a specific structural engineer who specialises in designing timber structures rather than steel, and the builders made it themselves.’

In the original house, the front two rooms and entry hall were retained, as dictated by the heritage planning requirements.

Post alterations and additions, the home is warmer, more efficient, and ultimately more beautiful.

The original house required new windows, weatherboards, insulation, flooring, plaster, and rewiring.

The bathroom features a lush outlook.

Timber cabinetry continues into the bathroom.

The double-fronted weatherboard facade was restored with a new porch and timber beams.

The main objective of this heritage house renovation by Ben Callery Architects was to design a ‘compact’ addition to an existing cottage, using all timber, to ensure a small footprint, both physically and environmentally.

The existing house was a heritage protected, double-fronted weatherboard cottage. ‘It was not ornate — very austere,’ says Ben Callery, director at Ben Callery Architects. ‘The front was in poor condition and it needed new windows, new weatherboards, new insulation, new flooring, new plaster, rewiring, a new verandah — the works!’

At the back of the house was a poorly-designed lean-to, that raked downwards towards the rear. ‘So there was no view of the sky from within, no sun and you were disconnected from the elements and the energy they provide,’ explains Ben.

The lean-to needed to go, but the owners (a couple who are engineers and project managers) desired efficient new spaces — both in construction and operation.

In response, the architects designed a new L-shaped, 77 square metre addition encompassing a new bedroom with an en suite, study, bathroom, European laundry, and an open-plan living, meals, kitchen area.

The addition utilises an all-timber structure including a king post truss that spans 7.3 metres, and allows perpendicular sliding doors to open. ‘The truss is the really unique element of this project, spanning the full width of the building and creating this great opening, with an engineered solution handmade from natural materials,’ says Ben.

‘We engaged a specific structural engineer who specialises in designing timber structures rather than steel, and the builders made it themselves… To have one element that expresses this ideal of using a lower embodied energy approach, while still achieving a great outcome, is really beautiful.’

The pitched roof speaks to the proportions of the original house, while providing a sense of volume and space greater than its modest footprint (107 square metres on a 278 square metre site) suggests.

Green accents across painted surfaces, soft furnishings, and landscaping by Straw Brothers tie the entire home together.

Outside, a new deck serves as an extension of the living area, under a pergola ready to be engulfed in deciduous vines.

In the original house, the front two rooms and entry hall have been retained, as dictated by the heritage planning requirements. The facade has also been restored with a new porch and timber beams.

With its clever use of space, and airy new extension that spills out onto the back deck, this home now makes the most of it compact size, whilst maximising as much back yard as possible. The result is a warmer, brighter, more functional and efficient home – with a small footprint, in more ways than one.
