Hugelkultur feasible for small lots?

I'm sold on Hugelkultur, works well from my experience thus far. What I wonder however, would hugelkultur be a good choice for small lots. ei. urban spaces/small yards or is there better methods that utilize space better?
Does anyone have experience with this in small areas? We know it works well in big open areas.

I was gonna chuck some rotting wood in my (very tiny) beds (3m2) & mulch over the top and call it Hugelkultur. Perhaps that's blasphemy but it's what works in my space plus with neighbours etc. I hope to build it up over time - I feel like towering hugelkultur mounds would work well if you can get around them. Maybe for next year....

A bit of a rambly post, but basically I have yet to get results and I don't see why it shouldn't work. Let's call it adapting.

I have seen hugelkulture beds in "city garden tours" and they seem to be thriving and doing well. The aren't super tall, but I think scale is relative to location.

I'm going to attach a picture of the logs I'm putting under the end of my berm to build out a hugelkulture bed on the tip.

The bottom is going to be logs, second layer leaves and evergreen boughs from yard waste collected around the neighborhood, and the third layer (top for now) is going to be wood chips.

... Not sure where to find that much dirt, but we're still digging in other parts of the yard, so we'll see. Hope I don't have to buy it...

Dear Jason,

You would want space enough to hold the dimension of the structure and for you to have space beyond the Hügelbed, without ending up in something that feels more like a prison cell. On the other hand I have been on some of Sepp Holzer´s seminars in urban areas with little space and here is what I learnt: One way around the lack of space is to set the Hügelbed on the edge of your garden and use it as the boundary or "fence" at the same time as using its inner side for planting whatever you want to harvest. Growing berry bushes like raspberries on the outside would do no harm and it might be a friendly gesture to pedestrians passing by and pinch a bit. The habit of building fences around gardens in Europe is quite common, not so much in the US as far as I know. A "Hügelbed fencing" might be a nice thing between a useful growing area that saves space and some kind of fence protection to your private area.

Thanks for the pics and all the comments. The idea of using hugelbeds as fencing sounds like a great use in small areas!
I can see that working well.
