Add Usable Square Footage Without Relocating

Diamond Brothers Construction builds home additions that integrate seamlessly with existing structures in Susanville, California.

You need another bedroom, a dedicated office, or a larger family room, but moving means leaving your neighborhood in Susanville and taking on the cost and stress of buying and selling. A home addition gives you the space you need without uprooting your household. Diamond Brothers Construction handles structural framing, foundation work, and finish matching so the new space looks and functions like it was always part of your home.

We provide seamless home expansion solutions that include room additions and layout integration designed to match your home's existing architecture. Structural framing and foundation work meet current building codes, and we coordinate inspections at each phase to ensure compliance. Exterior and interior finish matching ensures siding, roofing, flooring, and trim align with what is already there. The result is increased living space and home value without the disruption of moving.

What Happens Between Foundation Pour and Final Walkthrough

We begin by surveying your property in Susanville to confirm setback requirements and utility locations, then design the addition to integrate with your home's existing roofline and floor height. Foundation work includes excavation, forming, rebar placement, and concrete pouring, followed by curing time before framing begins. Structural framing uses engineered lumber and hardware rated for snow and wind loads common in the area.

Once framing passes inspection, you will see walls take shape, windows and doors installed, and roofing tied into the existing structure with flashing and underlayment that prevent leaks. Interior finishes such as drywall, flooring, and trim are matched to your home's current style so transitions between old and new spaces feel intentional rather than patched together. Electrical and plumbing rough-ins are completed before insulation and drywall go up.

We handle all permitting, coordinate inspections with the county, and ensure the addition meets energy code requirements for insulation and ventilation. The timeline depends on the size of the addition and weather conditions during excavation and roofing. We do not perform landscaping or irrigation work, but we grade the site to direct water away from the new foundation and restore disturbed areas to a level finish.

Common Questions About Adding Space

Homeowners considering an addition usually want to know how long the project takes, whether the existing house stays livable during construction, and how new spaces connect to existing rooms. These answers cover the most frequent concerns we hear before starting an addition.

How long does a typical room addition take?
Most single-room additions take two to four months from permit approval to final inspection. Larger or multi-story additions take longer, and winter weather in Susanville can delay exterior work such as foundation pours and roofing.
Will I be able to stay in my home during construction?
Yes, most homeowners remain in their homes during construction. We isolate the work area with temporary barriers, schedule noisy or dusty work during agreed-upon hours, and coordinate access so your daily routines are minimally disrupted.
How do you match the new exterior to my existing home?
We measure siding profiles, roofing materials, and trim details on your current home and source matching or closely coordinating products. If exact matches are unavailable, we provide samples and recommend complementary materials that maintain visual consistency.
What happens if we hit bedrock during excavation?
We assess soil conditions before excavation begins, but if bedrock or hardpan is encountered, we adjust the foundation design or use specialized equipment to reach the required depth. This may add time and cost, which we communicate immediately.
How do you tie the new roof into the existing structure?
We remove sections of existing roofing where the addition connects, install flashing and underlayment to create a watertight seal, and extend shingles or metal roofing across both surfaces. The transition is designed to shed water away from the joint and prevent ice damming in winter.
