Design Basics

Larry Trimboli Design & Drafting is the exclusive design, drafting and engineering service for Sierra Log & Timber. Larry Trimboli is the founder and president of Sierra Log & Timber and also the principle of Larry Trimboli Design & Drafting.


We custom design most of the homes we are commissioned for. But we have also assembled an extensive home design database in both log and conventional homes to help you find either the right floor plan to purchase or jump start the process of custom designing your dream home.

Sierra has partnered with three of the most notable home design companies in the market to offer our customers a huge database of home plans to choose from. The plans are purchased from Sierra as they are and then engineered and completed into a final engineered set of plans by Larry Trimboli Design & Drafting (Note: This is mandatory for some states, such as California, that require fully site-based engineering and plans in order to obtain a building permit.)
