domain driven design - Structure of a single bounded context

Question

Does bounded context span over all application layers (domain, application, presentation & infrastructure) or just domain model? For example should i use the following structure:

<bc 1>
 |_ domain
 |_ application
 |_ presentation
 |_ infrastructure
<bc 2>
 |_ domain
 |_ application
 |_ presentation
 |_ infrastructure

or the following:

domain
 |_ <bc 1>
 |_ <bc 2>
application
presentation
infrastructure

Answer 1

Both are valid approaches. I tend to favour the first option, because it allows better modularity and quite clear boundaries for high level BC. The second option is the 'standard' way of doing this, it favours let's say a more technical layering, while the first option literally favours a more domain driven layering.

Choose the one you feel more comfortable with.
