1. Relocated Restoration: When a structure is dismantled with the intent and care necessary to re-raise the structure elsewhere, we are certainly undertaking a restoration of the structure--just in a new location.
2. Historical Restoration: A preservation approach means that only what is necessary to ensure the soundness and continued existence of the structure is done, with the end result being a structure left as close to its original state as is feasible. This historical, museum approach includes documenting the structure before work commences, documenting the steps and methods of repair, and researching the deep background of the structure. The costs involved in such an invested process usually require that the structure have some significance to a community or group.
3. Renovation Restoration: In the construction industry, ‘restoration’ almost always refers to renovating and restoring a building to a resemblance of the original appearance and intended state of a building on the site it is found on. This sort of restoration usually includes the upgrading of structural and convenience utilities to modern standards for the convenience of its occupants and refining the structure for further residential or commercial use.
Traditional Timber Works has been involved in numerous undertakings to stabilize and renew antique structures, both timber-framed and hewn-log. Though we have not yet had the opportunity to undertake a documented historical restoration, we are competent to use traditional methods when reconstructing buildings on their original site, as well as in the relocated restoration work we already do. 
The process of on-site restoration involves a phased approach to the project. One phase of the restoration must be executed before the next can be undertaken--or even justified, if the condition of the overall structure cannot be fully evaluated without some exploratory work. After an initial evaluation of its condition deems the structure viable for restoration, the TTW approach would be:
1) repair or upgrade the foundation to ensure future stability
2) repair, clean, and make any needed improvements to the superstructure
3) rebuild and renew the roof system.
When these three phases are complete the structure has been given the opportunity for a second life. Whether its use is residential, commercial, public, or utility space, a structure that has a sound foundation, skeleton, and roof will serve well for years. If built using traditional, time-tested methods, it will serve for generations.
