I would recommend Inside Out Building and landscaping solutions if you're considering having landscaping work done. They have recently transformed my garden that consists of a steep slope that I couldn't climb to a tiered slope with levels. They did this using sleepers and built a fence too. All done in 4 days. They also had the added issue of not being able to gain access to the back garden without going through the house. They managed all of this and did all the work with tools that could be carried and hand held. It was also a very competitive quote. The team are friendly and courteous. Can't recommend them highly enough.
