This Tinners hut is at Fishlake. Most of the Dartmoor huts date from anything between the early medieval period to the modern era, however it is fair to say that the majority were constructed during the post medieval times (1540 - 1901) with some later examples. Albeit it tin, peat, rushes, or lush grazing, the best sorts are found in the remoter and inaccessible parts of the moor, usually by the upland streams and rivers or on the high hilltops. This then causes two problems for anyone wishing to exploit them; their remoteness and exposure to the Dartmoor weather. Having once found a good source of tin or peat the men had a choice, they could either commute to and from their find on a daily basis, in many cases this would have involved a trek of many miles. The alternative was to leave home on Sunday or Monday for their place of work and then stay there until the following Saturday, this meant they would need somewhere that was warm and dry to stay. This abode took the form of a hut which not only acted as their weekday residence it also served as a shelter during inclement daytime weather and as a storehouse for their tools etc. It would be fair to say that the more remote the tin sett or turf tie was from home the larger and more accommodating the hut would be. Whereas if the workplace was near to home and easily accessible then a daytime shelter rather than an abode was all that was needed. I copied and pasted this info for you.
