Can I put a sphere around my asteroid?

A different form and function of a Dyson sphere.

It is fairly far in the future and the residents of a D-type spherical asteroid (similar in size to Deimos, ~6km radius). They've been living in habitats and small domes dotted across the surface, with material shipped in and out. Instead of living underneath the ground, the mayor decided to investigate building a sphere around the whole thing, and pumping in atmosphere and materials to make the surface liveable.

Can this structure be built within reasonable expectations of the advancement of materials sciences and engineering as well as speculative materials? Will it be an impossible structure?

Dome: 100m above the surface, wrapping the entire asteroid with support structures as necessary and airlocked ports of entry/departure. With a 6.1km radius, it would have a surface area of 468km².

I can set aside the mechanism for filling this thing up with atmosphere, etc., but can I put a sphere around my asteroid? Keep in mind that it will have 1bar of pressure after it is completed. It can be closed (artificially lit inside/not glass).
