Building design & documentation services in Melbourne specialising in energy efficient, sustainable home renovations & extensions that will transform your house into a light, bright and inspiring new space

© Geometrica 2016


Geometrica is a sustainable building design practice formed by Logan Shield to create green, energy efficient house renovations and extensions that transform your existing home into a light, bright and inspiring new space

Design Philosophy

Geometrica creates design ideas for your home based on 3 main considerations:

You - the design must fulfill your lifestyle, space & budget requirements

Others - the design must respect its context, its neighbours & future owners

Environment - the design must respect the environment eg. minimise energy & resource use

Design Process

The process for home extensions and renovations is generally as follows:

Obtain clear project brief & budget

Schematic layout for use of space, solar orientation & zoning

Detailed design of shading, ventilation, thermal mass & interior

Select all materials, insulation &
energy efficient systems


We specialise in designing green, energy efficient house renovations and extensions in older inner city suburbs such as Brunswick, Essendon, Moonee Ponds, Ascot Vale, Flemington, Kensington, Footscray, West Footscray, Seddon, Kingsville & Yarraville

Victorian, Edwardian and Federation homes are often in a ‘heritage overlay’. Rather than viewing these planning controls as a nuisance, we see this as an exciting opportunity to create modern spaces
within a beautiful context


Geometrica is run by Logan Shield, a building designer who graduated from RMIT. He gained valuable experience in planning / building regulations & contract documentation with an architectural firm. He also spent many years with a heritage architect working on some of Melbourne’s finest buildings

Geometrica works with a range of other experienced consultants including structural engineers & energy raters who are selected on a project basis

Logan also holds a first class honours degree in Physics from the University of Melbourne


Geometrica is committed to reducing its
impact on the environment as follows:

Electricity is from 100% renewable resources

Rainwater is used for toilet flushing

Paper & plastics are recycled & e-waste donated to Infoxchange

Documents are either emailed or printed on 100% recycled paper
