DesigningWith Light
Why orientation and solar response matter in residential design.
Good design starts with understanding the site. Before a plan is drawn, the land is read — its orientation, its light, its outlook and the conditions that move across it through the day and the year.
01 — Site & Orientation
Understanding the site before the home
Orientation influences natural light, comfort, privacy and how a home connects with its surroundings. Living spaces, openings and outdoor areas are placed in response to the site rather than imposed upon it.
Slope, boundaries, neighbouring buildings and prevailing conditions all shape the early decisions — where the home opens, where it closes, and where it holds back.
02 — Summer & Winter Sun
Following the sun
The summer sun sits high and arrives from a wider arc; the winter sun is low and more direct. A home designed around this difference can welcome winter warmth into living spaces while shading the same glass in summer.
Eaves, screens, planting and the depth of an opening become quiet instruments of comfort — resolved in the design rather than added later.
03 — Light, Privacy & Views
More than simply finding north
Orientation is rarely a single decision. Natural light, shading, privacy, views and prevailing conditions are weighed together, and the best outcome is usually a balance between them.
A window may be placed for light and adjusted for privacy; an outdoor space may follow the afternoon sun but sit clear of a neighbour’s outlook.
A solar and shadow study builds an understanding of light, overshadowing and private open space. PTD carried out the solar and shadow analysis in this service example; the house design was not by Paul Triantis Designs.
