Me and my partner have moved into our first home during the pandemic. Our garden is built on a slope with the house being at the lowest. Outside the back door is a concrete area that has a cinder block retaining wall with step to the side leading up to the rest of the garden. I am looking at extending the downstairs to the concrete area and want to know if it possible to extend using the retaining wall adding a second skin inside without having to dig up the 5ft deep compacted earth on the other side.
