Move individual vertices around a little randomly to give character.
  
 Make good use of the Mirror Modifier and Solidify Modifiers to speed up workflow on basic shapes and apply them only when you want to break the symmetry and add finer details (destructive modeling). Scale can be applied on shapes (''CTRL + A'') but it is not mandatory and modeling can be done with scales other than (1,1,1). Make good use of the Mirror Modifier and Solidify Modifiers to speed up workflow on basic shapes and apply them only when you want to break the symmetry and add finer details (destructive modeling).

-Cut out windows and doors using the knife (''K'') tool in the base object. Then select the edges, duplicate and move them outwards, scale them down a bit, separate to make a new object, in that new object in edit mode extrude outwards and then add a solidify modifier. Careful that your normals face the right way. If you have mirrors not applied be sure to activate clipping so that the points on the mirror axes don't separate from each others when scaling down.+Cut out windows and doors using the knife (''K'') tool in the base object.

 It's handy to start with a boxed shape then inset faces and extrude them and scale them down along the normal to get quick good looking volumes. It's handy to start with a boxed shape then inset faces and extrude them and scale them down along the normal to get quick good looking volumes.

 +Applying modifiers is really up to you and depends on if you need to edit the full mesh (in which case apply) to break symmetry 
 +
 +Texture slots enable you to give different textures to different parts of a mesh. To do so, select the parts of the mesh and select another slot material and click assign.

 +Eevee vs Cycles : Cycles is a Ray based renderer while Eevvee is a screen based renderer. Eevee tries to keep things as simple as possible and kind of flat while cycles is trying to be as realistic as possible. Eevee is a real-time renderer while cycles is more resource intensive and requires many samples to produce good results.
 +Surfaces that are emissive will have a much better render in Cycles than in Eevee.

 +When beveling you can press ''CTRL + B'' and then ''V'' to bevel a vertex and create a triangle face where the vertex was. Direct shortcut is ''CTRL + SHIFT + V''. When beveling vertices, use ''J'' to join opposite vertices that were created to re-triangulate the faces and correct the geometry.

 +==== Making Spiral meshes ====
 +
 +Use addon tool : Add Curve : Extra Objects.
 +
 +  * Add an Archemedian curve spiral.
 +  * Tweak the Turns, Steps, Radius Growth and Height properties before validating the spiral.
 +  * Go into the Data panel and under Geometry > Bevel add some Depth. Activate Fill Caps option.
 +  * Convert the curve to a mesh and go sculpt.
