From the field · Murphy
“An addition in Murphy is half permits, half craft. We pre-meet with the city’s plan review before drawings are stamped — that’s why our additions break ground 6 weeks after contract, not 14.”

Co-Founder, Construction Lead

Do I need a structural engineer?
+
Yes — every addition we build includes structural engineer review. The cost is included in our fixed quote.
Can you match my existing exterior brick / siding?
+
Yes. We source manufacturer-matched brick, stone, and siding. For discontinued lines, we work with local brick dealers to find aged-match material.
How disruptive is an addition?
+
Less than a whole-home remodel. We seal the existing house with vapor barriers during framing and only break through the load-bearing wall at the very end of construction.
Do you handle the foundation?
+
Yes. We pour all-new slab or pier-and-beam foundation depending on what your existing house uses.
Will an addition need HOA approval?
+
Almost always. We prepare full ACC submissions including elevations, materials samples, and site plans.
Can I add a second story?
+
Sometimes. We bring in a structural engineer first to check if your existing foundation and load-bearing walls can carry the additional weight.
Is the quote really fixed?
+
Yes. Once design is locked and permits are submitted, your price is your price.
