This pint-sized home within the inner-Sydney suburb of Glebe, constructed within the yard of a bigger residence, was designed to assist versatile occupation by the homeowners and their household. The homeowners have a spot within the Blue Mountains and needed a metropolis pad that could possibly be utilized by them, their household or short-term renters. They selected architect Simon Anderson and his staff for his or her experience in sustainable design and, along with the builder, took the plunge into the world of passive home design. This undertaking marked the primary time that Anderson Structure had utilized for passive home certification and it’s, on the time of writing, the smallest licensed passive home in Australia.
On method, Pocket Passiv is distinctive on the street. Set ahead to fulfill the footpath, its sloping roof, shingle-clad exterior and apparent small stature entice the attention. Actually, the steeply pitched roof was a necessity so as to not block the daylight within the neighbour’s yard: the winter solar’s slope was mapped and the constructing formed to that specification. This constructing envelope constraint additional sophisticated the design as a result of it added a sloping roof to the puzzle of the tiny home. Regardless of this, the architects managed to suit two storeys right into a 27-square-metre footprint, bringing the ceilings low and positioning the kitchen into the slope of the ceiling.
Licensed as Passive Home Plus, the studio produces as a lot power because it consumes.

The ensuing house is cosy, however not cramped. Getting into on the bottom stage, occupants descend two steps from the entry into the bed room to the left, with the staircase on the proper. A mattress is positioned beneath an extended horizontal window at eye stage. Constructed-in furnishings and storage abounds: a desk and cabinets sit subsequent to the mattress, whereas cabinets and drawers are housed underneath the steps. There’s even a hidden cabinet underneath the entry stairs. “I grew up on boats, and I do recognize all of the methods they create storage,” Simon explains.
Past the bed room is a double-height toilet completed in white tiles, terrazzo-look porcelain and a timber benchtop, with a skylight permitting a view of the sky. Within the nook is a bit cutaway, which at first appears unremarkable however in reality is proof of the architects’ ingenuity: working round an present sewer. Timber particulars within the toilet additionally tie in with the ceiling within the bed room, the place structural timber joists have been left uncovered. These joists are uncooked, however removed from unfinished – as an alternative, the timber makes the interiors really feel heat and provides character. Beneath the ground is one other innovation: perlite – a cloth typically utilized in gardening – was combined into the tile mattress at a ratio of three elements perlite to 1 half cement. “This offered simply sufficient insulation to the lavatory tiles from the slab underneath, that means the tiles don’t get chilly underfoot,” explains Simon.
A sunken ground-floor stage accommodates sleeping and bathing areas.

Above the steps, an outsized paper lantern performs with scale. An identical juxtaposition of small and huge additionally unfolds on the facade, the place enormous black metal window surrounds exaggerate the precise window sizes, particularly the first-floor openings, whose frames bulge out and above the facade’s edges – a intelligent visible phantasm that makes small apertures on a small constructing really feel large.
Upstairs, the kitchen bench is positioned alongside the again wall, tucking joinery into the sloped ceiling. A skylight above the sink provides extra headroom in a spot the place the occupant would possibly stand for some time. The higher flooring is small, however each trick has been used to maximise utility – there’s built-in seating across the home windows, a TV that appears like a murals, a small-sized fridge and dishwasher, even a foldaway eating desk hidden within the kitchen bench.
The facade is wrapped in cedar shingles and options two expressive window hoods that stretch out and up.

Contained in the studio, the acoustic high quality is instantly obvious, because the noise of the road disappears. That is due to the rules of passive home design: an ordinary for buildings that obtain thermal consolation with minimal synthetic heating and cooling, partly attributable to an emphasis on airtightness and excessive ranges of insulation. The studio’s power effectivity is achieved via photo voltaic panels, a warmth pump, high-performance home windows, insulation and cladding that cut back thermal bridging. In the meantime, fastidiously chosen materials finishes protect inside air high quality. The undertaking was Simon’s first deep-dive into passive home certification and, after many tweaks, the constructing has been licensed Passive Home Plus. This ranking acknowledges the constructing can function at internet zero power, that means it produces as a lot power because it consumes. “As a result of the home is so small, the smallest change or replace to the thermal modelling has dramatic results,” explains Simon. “An excessive amount of insulation would imply the house overheats in summer time, and too little means it might be too chilly to fulfill the stringent standards that Passive Home requires.”
Whereas this house could also be small, it punches above its weight in relation to environmentally accountable design. Pocket Passiv demonstrates how infill housing within the internal suburbs can add density to our cities, whereas additionally enabling occupants to reside effectively in small areas.
