Add Space Without Moving

Home additions let you gain the square footage you need without the stress and expense of relocating. Stay in your neighborhood, keep your kids in the same schools, and expand your home to fit your lifestyle. More cost-effective than buying and moving.

Increase Home Value

Well-designed additions provide strong ROI - typically 50-80% of construction costs returned at resale. Master suites, additional bathrooms, and living space are highly desirable features that attract buyers and increase property value significantly.

Seamless Integration

Professional additions blend perfectly with your existing home - matching rooflines, siding, windows, and architectural details. When done right, additions look like they were always part of the original structure, maintaining your home's aesthetic integrity.

Addition Process

Here's what to expect during your home addition project.

1

Design & Planning

We meet to discuss your space needs, budget, and design preferences. Our team creates detailed plans showing how the addition integrates with your existing home. We review architectural drawings, select materials, and finalize the scope before moving forward.

2

Permits & Engineering

We prepare construction documents and submit permit applications to your local building department. For larger additions, we coordinate with structural engineers to ensure proper load calculations and foundation design. This phase typically takes 4-8 weeks.

3

Foundation & Framing

Once permits are approved, we excavate and pour the new foundation. After curing, we frame the addition walls, roof, and integrate with your existing structure. Windows and doors are installed, and the addition is weatherproofed before moving to interior work.

4

Systems & Finishing

Electrical, plumbing, and HVAC systems are installed and inspected. We insulate, drywall, and finish all interior surfaces. Flooring, trim, painting, and fixtures complete the space. Final inspections ensure everything meets code before you move in.

Total timeline: 5-9 months from design to completion. Varies based on addition size, complexity, and permit processing times.

Frequently Asked Questions

Common questions about home additions and our process.

Home additions typically cost $200-$500 per square foot depending on complexity and finishes. A 300 sq ft master suite addition might run $60,000-$150,000. Second story additions cost more ($250-$500/sq ft) due to structural requirements. We provide detailed estimates during consultation.

Timeline varies by project size: Design and permits (6-12 weeks), Construction (3-6 months for most additions), Final inspections (1-2 weeks). Total project timeline is typically 5-9 months from initial design to completion. Weather and permit processing times can affect schedule.

Most families stay in their home during addition construction. We work to minimize disruption, but expect noise, dust, and limited access to certain areas. For second story additions or major structural work, temporary relocation might be more comfortable during critical phases.

Yes - matching your existing architecture is a priority. We carefully coordinate rooflines, siding, windows, trim details, and proportions so the addition looks original to your home. Our goal is seamless integration where you can't tell where the old structure ends and new begins.

Home additions require building permits (structural, electrical, plumbing, HVAC), and possibly zoning approval depending on setbacks and lot coverage. We handle all permit applications, coordinate inspections, and ensure work meets building codes. Permit fees typically run $2,000-$5,000.

Possibly - it depends on your existing foundation capacity and local zoning. Second story additions are great for small lots but require structural assessment to ensure your foundation can support the additional weight. We coordinate with engineers to evaluate feasibility and design safe solutions.
