I recently found this book on amazon: The Authentic Tudor & Stuart Dolls' House by Brian Long. It is an awesome resource for miniaturists wishing to create authentic historical doll houses of the Tudor & Stuart era, focussing on 1603-1625. The book is aimed at 1/12 scale doll houses but it is an equally great resource to scratch-builders of tabletop scenery. Covering all relevant aspects such as timber frames, roofing and interior, and giving illustrations and colour photos this book provides all the info you need to build an authentic half-timbered house.
Once I finish my batch of Tabletop World houses and have some free time I look forward to scratch-building a house with this book as a guideline.
