From Tasheni's original description: 
Kintyra Castle lies in the Tundra in the vicinity of Whiterun, just turn right at Fort Greenwall and follow the way over the bridge. Besides the
main buildings lies a tournament area and several big stables for your
horses. Discover the Manor with kitchen, chambers, the Oblivion Memorial
room and the children's quarters. Discover the Knight's Hall, the
Mansion and several towers. Work your Alchemy in the Loft or your Arcane
Arts in the Mages Tower. Explore the Administration Quarters with
Library, Office and Living Rooms.  And there is a lot more to discover.
And plenty of storage for all your weapons, treasures and whatever you
want to collect: Roundabout thirty rooms for you to explore.

When I finished the fantastic mod Rigmor of Cyrodiil, I felt I needed a more
fitting home in Skyrim, and I'm also a huge fan of Mr Siika's Castle
Seaview in Cyrodiil, so I decided to puzzle all his assets and other
together to make a castle that fits my needs. It is eyecandy in the
first place. But look for yourself.

There are no followers, companions, npcs included. You need to bring them in yourself.

This castle comes as is. I have no time to do bug fixes, patches and
improvements, maybe this will take place in the future, but no promise.
It is obviously not compatible with mods who cover the same area, mods,
who change the landscape or add trees to that area. Look at the
screenshot for the exact location.

There is no quest or fee to occupy the castle, just take it. Maybe you find this boring, but
my sparse time doesn't allow me to go any further.

I did tests with seven followers and two doggies and it worked very well. I did not test with children.

Bugs: There are some wrong texture paths for several dishes, but they are
mostly inside a container, you don't have to use them. The candle
lighting does not work correctly with some candles, but this is not
immersion breaking.
There is light flickering in some rooms - don't activate every light source you will find, find out, what source works
best for you.
Followers will not follow up the steps in the towers or in the Guardhouse. The steps are very steep - nothing I can do about
it. If you change the cell, they will most likely teleport to you.
In the Treasury the Sanguine Rose Staff is shown in the rack - should be
invisible. But it's a static object, you can't grab it, you need to get
the Skyrim quest done to place the original staff here.

If you discover bugs - I'm sure there will be some - feel free to report them here.

Skyrim has fantastic skilled and talented modders, who give their permissions
freely and I want to say a big, big, thank you for all the assets I'm
allowed to use. Please notice the credits list. It's very long.

FAQ:
- Why do you use 1k textures?
- Because my computer is at their limits. And the mod uses a ton of different textures and is really huge enough.

- Are there weapons or armor included?
- There is one armor and you will find some weapons, but this is mainly a player home mod.

- Does the interior of the buildings fit the exterior?
- No, unfortunately not. I'm no architect. But I tried my best to stay close to the layout, as far as it was possible for me.

- Are there npcs included?
- Just some horses and hens. Very basic. Use mods like Convenient horses, follower mods or whatever you prefer in addition.
This mod is the foundation to further improvements you may do yourself. I
built the market area with vendors in mind, and every resource you need
to craft something should be available in the area of the castle, so
were my thoughts. There are some new ingredients, but this is not
finished. Feel free to get into creativity and do what you want :)

I would love to see your screenshots :)
