Our latest software and powerful computer hardware allow us to virtually build a 3D model of your future home. We are then able to produce high quality 3D movies and animations of your future home using a program called BIMx .  This powerful visual tool allows you to “visit” your home inside and out. which gives you the ability to make all of the right decisions concerning your home. Therefore, YOU are in control instead of being in the dark during the design process.  

Certain projects constructed in British Columbia require the involvement of an architect.

Our Plan of the Month: Straw Bale House

This split level straw bale home is using round logs inside post and beam structure with the 18” wide straw bale perimeter wall wrap around the logs as a heavy insulated envelope.  Entry is to the south directly in the public area (kitchen, dining and sitting).  Footprint to exterior face of straw walls is only 1216 sq.ft. with 1744 sq.ft. living space not counting basement.
Basement has extra bedroom suite plus a large wood storage which make this house a four bedroom dwelling.
Owners plan to build a masonry stove to radiant heat main floor, second floor with two bedrooms and master suite at top floor.  A very energy efficient well thought out project is also a passive solar design taking advantage of south facing slope with little wall face exposed to North.  Roof has large roof overhangs to protect the Cobb exterior wall finish.
I love this tiny home because it is so cost effective to build with much creativity.
