Chadwell's Exclusive Cottage

A circular cottage, 20' in diameter and 15' tall at the peak of its roof, springs into existence in an unoccupied space you can see on a solid surface large enough to hold it and remains stationary for the duration.

10 creatures of Medium size or smaller can be inside the cottage with you. A large creature counts as 2 and a small creature counts as 1/2. No creatures beyond this limit are able to cross the threshold. Creatures and objects that you specify may enter and exit the cottage at will. All other creatures and objects are barred from passing through it. Spells and other magical effects can't extend into or be cast through the cabin. The atmosphere inside the space is a comfortable temperature and dry, regardless of the weather outside.

The caster decides on the appearance of the cottage when it is cast and may designate any non-magical items to appear inside the cottage (e.g. beds, tables, bathtubs). Any items created by the spell cannot be removed from the building and will disappear immediately if anybody attempts to remove them.

The cottage can have 1 or 2 doors and a number of windows specified when it is cast.

Inside the cottage there is a sleeping loft and a small kitchen including a wood stove.

If the cottage remains in the same place for a full year it will become permanent. If spell slots are used in this process rather than ritually casting this spell then it becomes permanent as soon as 200 levels worth of spell slots have been expended, e.g. 40 castings using 5th level slots.

When the caster becomes capable of casting 6th level spells the duration of the cottage increases to 24 hours. When the caster becomes capable of casting 9th level spells the duration of the cottage becomes 1 week.
