HOUSING + MIXED-USE MULTIFAMILY

Design and Engineering for Modern Housing Developments

Residential development is a complex process involving multiple partners, strict permitting requirements, and site-specific challenges. AHBL streamlines this process by providing comprehensive expertise—from master planning and feasibility studies, such as site evaluations and utility reviews, to prepare clear documentation for permitting, bidding, and construction.

We work with local and national builders alike from raw site development to final site development and occupancy. We ensure effective coordination with local agencies and project partners to maintain predictable schedules and integrate infrastructure across single-family, multifamily, mixed-use developments, senior living, and affordable housing.

With multidisciplinary expertise in civil engineering, structural engineering, landscape architecture, land use planning, and land surveying, we deliver planning and design services that support resilient and functional residential developments across Washington State.

Housing Projects We Deliver

AHBL is the driving force behind a wide range of single-family and multifamily residential and mixed-use developments, as varied as compact infill projects to large-scale housing developments. We help project teams navigate zoning requirements, site feasibility, and infrastructure improvements while designing for new construction and phased redevelopment.

Our experience includes:

  • Affordable housing and low-income communities
  • Assisted living, senior housing, and community-serving residential facilities
  • Feasibility studies
  • Master planned communities
  • Multifamily housing
  • Roadway design, parking lots, circulation, utilities, and water systems
  • Single-family subdivisions and neighborhood-scale development
  • Townhomes, condominiums, and residential mixed-use building

How We Deliver for Housing Clients

Residential development involves many partners, complex permitting requirements, competing priorities and deadlines, and site-specific challenges. AHBL provides expertise that helps projects remain coordinated and on schedule.

Planning and Feasibility for Residential Sites

We assist with site evaluations, including plat layouts, utility capacity reviews, grading analysis, and due diligence to help determine feasibility for new construction, redevelopment, or renovations.

Clear Documentation for Permitting and Construction

AHBL prepares plans, reports, and technical documentation for entitlement, permitting, bidding, and construction. Our work helps project teams and stakeholders understand site constraints, infrastructure needs, and project requirements.

Coordination with Agencies and Project Partners

Housing projects require alignment with municipalities, utility providers, architectural teams, and development partners. We coordinate efficiently and effectively to support project management, maintain predictable schedules, and integrate infrastructure design with building layouts.

Designs That Prioritize Long-Term Performance

We focus on systems that ensure long-term maintenance, sustainability, accessibility, and operational needs, developing housing solutions which will stand the test of time. Our design approach helps owners plan for lifecycle costs and durable residential environments.

Our civil engineers help project teams evaluate alternatives, coordinate utility planning, and implement cost-effective solutions and value engineering to deliver final site development meeting our clients’ expectations.

  • Structural Engineering

    AHBL’s structural engineers design systems for townhomes, multifamily residential buildings, and mixed-use structures. We balance seismic requirements, constructability, lifecycle considerations, sustainability, and long-term performance to address a wide range of residential project types.

  • Landscape Architecture

    Landscape design plays a crucial role in livability, community engagement, quality of life, and long-term maintenance. AHBL designs open spaces, pedestrian networks, planting plans, and outdoor amenities that promote resident wellness and support sustainable site practices. Our work consistently integrates accessibility, circulation, low-maintenance landscapes, and stormwater-friendly design.

  • Land Use Planning

    Our planners help teams navigate zoning, land use regulations, permitting processes, SEPA requirements, and redevelopment scenarios. We oversee master planning, feasibility studies, and coordination with jurisdictions to help ensure projects align with community plans and regulatory frameworks.

  • Land Surveying

    Before ground is ever broken, every neighborhood starts with a diligent, detail-oriented land survey. AHBL provides boundary and topographic surveys, construction staking, utility research, and site documentation for site planning, grading, and infrastructure improvements.
