House design: Site selection – Orientation and site ratio


Hello listeners, this is Anton from inFORM design studio. As part of my posts on SITE SELECTION; today I am talking about orientation and site ratio. Both of these is greatly considered in the design process and shape the planned form and shape of the building very much. In short we need to look at wind and sun. in this post, I mainly look at sun. Every side of the building does negate a different design response through the year and through the day. If we look at the four sides of the building typically north, east, south and west. We need to look at the movement of the Sun and then have a design response. I believe north is the best side to face the building. You have to then think when you do look at a site and where the views are, and how you want to respond in terms of your design or design responses. North is the easiest, you can manipulate the sun to penetrate the building in the winter. If you have things like a concrete slab you can capitalise on thermal mass. In the summer you can shade the sun to not have the sun penetration, have good ventilation and have a cooler space. East is warm in the mornings? Not so bad? Not not as great as north but you’re going to have warm in the mornings. South still okay. We are in Queensland. It is warm most times of the year or a big part of the year. You just have to accept that there’s a part in winter which is going to be a bit chilly. West is very difficult. You got that low western sun in the afternoon; very hot. If you have views to the west and you want your building to live out to the west you have to accept that you need to look at screening devices to keep out that hot western sun and a massive heat load to the building. Now I’m getting into ratio and I take a little bit of a step back to Profile of the land as well. I’ll look at two different projects to explain that. I find a longer site with longer north-south Elevation is working best. I get more rooms facing north which allow me the easier orientation to the north, working with that nice northern Sun. I can have limited spaces on the east and the west Easily put some, garages or laundry spaces to the west. Limited windows on the east. You can still have bedrooms on the east easy to do bedrooms on the south. Very easy to work with that. So if I look at this site over here you could see the ratio would be longer north, north-south orientation. Nice to put the building. What would have worked really well in this building is the fall of the land were high on the south low on the north. Would have been a great site work works with. This is a floor plan on an ideal site. Which got a long northern orientation. We could put all our living spaces, rumpus and two bedrooms on the northern elevation. We could put kitchen, bathrooms, laundry, linen room on the south. We could put bedroom on the south. Another bedroom on the south. Has no windows on the west completely screened from the west. We only have a little window there for some cross ventilation in the master bedroom. If you look at this design there is literally only a little bit of corridor over there; a very economical plan, no wasted space. And a great outcome. The client was very happy. That’s probably it for for this post, I look forward to the next post. Goodbye
