Services Offered

Second-Story Additions

Kirmina Construction builds second-story additions for homeowners looking to add bedrooms, bathrooms, or living areas without reducing yard space. This type of project is particularly suited to growing families or those wanting to increase their home's usable square footage. Designs are tailored to match the existing architecture of the property.

Room Extensions

For homeowners who want to expand existing rooms rather than build upward, Kirmina offers room extension services. Common projects include enlarging kitchens, living rooms, and master suites. This can be a more cost-effective alternative to relocating to a larger home while still modernizing outdated layouts.

Outdoor Living Expansions

Kirmina Construction also handles outdoor living projects such as patios, decks, pergolas, and sunrooms. These additions are designed to extend usable living space and take advantage of California's climate. Such projects can also contribute to a property's curb appeal and resale value.

In-Law Suites and Guest Quarters

The company builds in-law suites and guest quarters — private living spaces on the property that include separate entrances, kitchens, and bathrooms. These spaces are suitable for multigenerational households or can serve as rental units. This type of construction falls within the broader category of accessory dwelling unit work, making Kirmina a relevant option for those searching for an ADU contractor or in-law suite builder in the Riverside area.

Garage Conversions

Kirmina also converts existing garage spaces into functional areas such as home offices, gyms, or studio apartments. As a garage conversion contractor, they work with the existing structure to avoid the need for major expansion, making it a relatively cost-efficient way to add usable square footage to a property.

Project Approach and Credentials

Kirmina Construction assigns a dedicated project manager to each job and provides detailed cost estimates upfront, with no hidden fees. The team communicates regularly with clients throughout the process and works to stay within agreed budgets and timelines.

Their credentials include:

  1. Certified Class B General Contractor, License #1124572
  2. Fully insured and compliant with California building codes
  3. Experience in home additions, ADUs, kitchen and bathroom remodeling
  4. Use of durable, quality materials throughout all projects
