Richard,
Those are all different views of the same house. There is no way any software could automatically take your original sketch and fill in the details of a view from the back <

Whoever did this took the original drawing as the basis for creating a 3D model of the house and surroundings. They could have simply made appropriate modifications to an existing model. 3D lends itself to re-using existing 3D objects. Notice that the leaves of the trees in several views consist of simple triangles or polygons. The basic model consists of a wireframe of polygonal 3D modeling. Textures that could have been created in Photoshop are mapped to the wireframe.
The advantage of this approach is that once you have expended the effort to create the model, you can easily create many different rendered images from various vantage points and under different lighting if you wish. This example doesn’t show a lot of detail, so it probably took only a few hours to build.
The plants may have been imported as sort of 3D clip art. Notice that the plants cast intricate shadows. The bricks are just a texture pattern such as you could create in Photoshop. It’s quite possible that all of the colors you see here, including bricks, grass, sky, painted surfaces, etc., were all created in Photoshop as texture maps for the 3D model.
I think all of the Poinciana Point views <
http://www.dreamimageco.com/PoincianaPoint/> shown were from the same 3D model. Once you have built the model you can easily create as many different views as you wish. If the model included interior detail, you could have interior views as well. You could also create a walkthrough video or post the model for interactive 3D viewing on the Web.
There are several 3D software applications that could have been used to create those various views of the Poinciana Point house, ranging from inexpensive to quite expensive. It could have been a 3D CAD program or even a shareware program. No way tell from just looking at these images. If the creator had used some fancy features like detailed raytracing, radiosity, etc. that would have been a tipoff that a more expensive program was used.
But these examples could have been created by an inexpensive program. The brick driveway and grass looks kind of "fake", like it was painted on a plane. This would have looked a bit more convincing if the modeler had created a little shape to the driveway surface and the lawn surface.
