Three CSLB classifications under one roof — general building, landscape and site work, and swimming pools. On a Diamond Bar view lot the retaining, the drainage and the pool deck are a single design problem.
Room Additions & Framing

Elevated and terraced gunite pools, replaster and tile, deck replacement and equipment upgrades on sloped lots. Pool construction and remodel →
Patio Covers & Hardscape
View decks, shade structures, outdoor kitchens and hardscape engineered for the slope they sit on.
What We Design For
Conditions Particular To Diamond Bar, CA
Puente Hills Clay
Expansive clay through much of the city moves with moisture, and parts of the hills carry a documented landslide history. Footing and wall design follows a soils report rather than an assumption.
Hillside Management Standards
Above certain slopes the city governs grading quantity, pad design and wall height. That decides what is approvable, so it is settled at design rather than at plan check.
Steep Driveways And Tight Access
Equipment access is frequently the binding constraint. Pump trucks, haul routes and staging get planned before a schedule is promised, because here they are the schedule.
Views Are Part Of The Scope
On a view lot, wall heights, deck elevations and structure placement are worth as much as the square footage. We design around the view rather than into it.
