Added Dimensions Inc

What Added Dimensions Inc does

Added Dimensions Inc. is a private general contractor founded in 1997 in Takoma Park, Maryland by Alan Kanner and Richard Hazboun, both former employees of the DC nonprofit housing developer Manna, Inc. The firm specializes in the construction execution of complex, design-forward contemporary architecture in the Washington DC metropolitan area, operating with a team of over twenty people whose collective experience the company describes as "hundreds of years." Service delivery is organized into three categories: New Houses (ground-up residential construction), Improved Houses (renovations, additions, and whole-house remodels), and Not Houses (commercial and institutional projects such as retail buildouts, community facilities, and lobby/common-area renovations). The company does not self-design; instead it works as a builder-of-record in tight collaboration with a network of 25+ named architectural firms including McInturff Architects, Robert M. Gurney, StudioMB, KUBE Architecture, David Jameson, and Ziger|Snead.

The business model is project-based custom construction services sold B2B via architect referrals and direct engagement with end-clients (homeowners and a small number of nonprofit/commercial clients such as Politics & Prose and Washington Youth Garden). Pricing is custom per project scope and not publicly disclosed; compensation for the firm's trade labor is structured with top pay plus bonus, 100% employer-funded health/dental/vision, employer-funded 401(k), tool allowance, company vehicles, and devices — consistent with a strategy of using above-market wages to attract scarce skilled trades talent in a tight DC labor market. The company is bootstrapped, founder-owned, and has no disclosed outside funding, parent entity, or subsidiaries; it reports no revenue, has no software products, no APIs, and no AI/technology component. Geographic scope is the Mid-Atlantic/DC metro region. Notable differentiators are precision craftsmanship on projects with no margin to conceal flaws, a collaborative builder-architect-owner team model, and a sustained recognition record including multiple AIA chapter and national-level design awards (AIA Maryland, AIA DC, AIA Virginia, AIA Northern Virginia, AIA Potomac Valley) from 2002 through 2023, a Home & Design 2022 Grand Award, a Remodeling Big50 honor, and a 2023 Wall Street Journal feature.

Scale indicators3 records

Recent moves5 records

Expansion highlights4 records

Broad incumbents

• Toll Brothers: Toll Brothers is a national luxury homebuilder with significant DC metro presence in the high-end segment. While massively larger and production-oriented, it competes for the same affluent residential customers in DC and offers a useful public comparable for valuation context on high-end residential construction demand.
• Case Design/Remodeling: Case Design/Remodeling is a larger, multi-location design-build remodeling firm serving the DC metro with broader operational scope than Added Dimensions. Comparable as both a remodeler and a competitor for high-end projects, but operates at significantly larger scale and broader customer mix.
• Winchester Homes: Winchester Homes is a larger regional production builder in the DC metro offering semi-custom and custom homes. Tangentially comparable through shared custom-home geography and customer base, but materially larger scale and distinct business model relative to Added Dimensions' bespoke-craftsmanship positioning.
• Clark Construction Group: Clark Construction is one of the largest commercial and institutional general contractors in the DC metro with extensive institutional and commercial buildout work. Comparable through shared DC-metro commercial/institutional execution (e.g., Writer's Center-class projects), but at vastly larger scale and broader portfolio than Added Dimensions.

Direct peers

• Pyramid Builders: Pyramid Builders is a Bethesda-based custom home builder specializing in architect-designed luxury homes across the DC metro. Overlaps with Added Dimensions on architect partner relationships, contemporary design execution, and high-end residential clientele.
• Studio Builders LLC: Studio Builders is a Bethesda-based custom residential design-build firm working with leading architects on high-end homes in the DC metro area. Overlapping focus on architect partnerships, contemporary design, and premium craftsmanship makes it a direct peer to Added Dimensions.
• BOWA Construction: BOWA Construction is a McLean, Virginia-based design-build remodeling and custom home firm serving the DC metro luxury residential market. It is the closest direct competitor to Added Dimensions, with the same architect-partnered, premium-craftsmanship model focused on high-end residential projects in DC/MD/VA.
• Morningside Custom Builders: Morningside Custom Builders is a DC-area custom home builder focused on architect-designed luxury residences. Same target customer, architect-collaborative model, and high-end residential scope as Added Dimensions.
• Sydmar Construction: Sydmar is a custom home builder serving affluent clients in the DC metro with a focus on high-quality residential construction. Comparable through shared custom-residential focus, premium service model, and architect-collaborative delivery.

Others

• Habitat for Humanity of Washington DC: Habitat DC is a nonprofit affordable housing developer and builder in the DC region. Added Dimensions' founders met while working at Manna, Inc., a DC nonprofit housing developer, and the firm engages in select community projects (e.g., Washington Youth Garden Pavilion), making Habitat an adjacent ecosystem peer rather than a competitor.
