Build New Hugelkultur Bed in Winter?

We plan to add a few new garden beds this year, and I'm wondering if I can prep them in late winter for spring planting?  Everything I've found says ideally you start them in fall, but we missed that boat.

Our plan is to layer cardboard, larger sticks, smaller sticks, rotted hay, compost, topsoil, then leaf mulch.  Currently we have snow on the ground, which might melt this week, but the ground is frozen solid.  

We aren't digging, just building up from the cardboard weed barrier.  Thoughts?

Reminds me of an old saying ... the best time to plant an oak tree was 25 years ago. The second best time is today.

Go for it!!!

I would echo the idea of get it done sooner than wait later if possible.

I will agree, start the beds now so thing can get settled and start breaking down.
