We provide shadow diagrams to illustrate OVERSHADOWING and / or SOLAR ACCESS.
Overshadowing is concerned with how the proposed building will cast shadows over key areas. These key areas include neighbours living room windows, private open space, and other adjoinging areas that need to maintain the amount of sunlight.
You will need overshadowing shadow diagrams if you are the designer / owner of the proposed building that will be casting the shadow.
OR
You will need overshadowing shadow diagrams if think you might be affected by such a proposed development, ie a neighbour.
Our shadow diagrams are very clear and accurate, and are produced for any time of the day / date and therefore are designed to satisfy all regulatory planning requirements.
Solar access shadow diagrams are similiar to overshadowing shadow diagrams, however the prime aspect these illustate are the amount of sunlight reaching certain key areas. These key areas include living rooms of a proposed design and or adjoining private open space / courtyards etc.
The solar access shadow diagrams clearly show the amount of sunlight available to the key areas and therefore can demonstrate compliance or non-compliance to regulatory planning codes applicable.

OVERSHADOWING SHADOW DIAGRAMS take several different styles, depending upon the key areas requiring examination. Typically they fall into three broad categorys:
PLAN - top view plan, showing existing shadows and proposed shadows. These are the most common and provide a general and clear overview of the movement of shadows accross the site.
ELEVATION - a side view ie NORTH ELEVATION - this clearly shows windows and the impact of both shadows and solar access upon these areas. Most useful for critical windows of either the proposed design or adjoining neighbours.
3D VIEW or AXONOMETRIC - this is a 3D view, either from a fixed point (perspective) or as a axonometric (parrallel projection) view. Axonometric shadow diagrams provide a mixture of benefits of both the PLAN and ELEVATION styles. The limitation is that they tend to be very specific on one particular area of the design and are more difficult to scale. The benefit is that they are extremely visual and a clear understanding of shadow and solar access projections is provided.
We have listed our three types in order of typical demand both in the market place and in planning controls.
COUNCILS -
We have worked with and advised many NSW Sydney councils, including
In other states we have been called into provide solar access and Shadow Diagrams where the council or a adjoining neighbour have become concerned with a proposed design.
