Home Addition

Most contractors who do additions work from plans you bring them. We’re different. We have an architect, a structural engineer, and a designer working with us — which means we can take your project from the initial idea all the way through permitted construction drawings, without you having to hire and coordinate those professionals separately.

For homeowners, this matters practically. You don’t have to find an architect, wait for drawings, then find a contractor to price them, then go back to the architect when the contractor has questions. We handle that entire process as one team. The design is built around what we know is constructible, and the construction is built around what was actually designed. That coordination saves time, reduces surprises, and produces better results.

We handle additions ranging from 300 to 1,500 square feet across a range of project types.

Ground-floor room additions – the most common scope we see. These are rear or side additions that add a defined new space to the existing footprint — a family room, a bedroom, a home office, a sunroom. The addition ties into the existing structure at the foundation, framing, and roof level, with exterior finishes matched to the existing home.

Second-story additions – adding a full or partial second story means the existing first-floor structure has to support the new load, which requires careful engineering assessment before any design work begins. We evaluate the existing foundation and framing capacity as part of the planning process and build the structural design from there.

Garage additions – whether attached or detached, garage additions involve their own foundation, structural framing for the door opening, and exterior integration with the existing home. We’ve built garage additions across Bucks County and Montgomery County and understand what local townships require.

Homeowners who’ve done interior remodeling projects are sometimes surprised by what an addition involves. A few things we discuss with every client upfront.

Engineering comes first – before any design can be finalized, we need to understand what the existing structure can support, where the foundation sits, and what the lot setbacks and zoning allow. Our structural engineer assesses the existing conditions and the proposed addition together, so the design is based on reality rather than assumptions.

Living in the home during construction – most of our addition clients stay in the home during the project, and we plan our construction sequence accordingly. The connection point between the old and new structure is the most disruptive phase — we plan this carefully to minimize how long the house is open to weather and how much the living space is disrupted.

We manage the full scope from design through completed construction:

In-house design and engineering — our architect develops the design, our structural engineer sizes the foundation and framing, and our designer helps with interior selections and exterior finish decisions, all as one coordinated team.

Initial consultation and estimate – we come to your home, walk the site, review what you’re trying to accomplish, and give you a realistic picture of what the project involves and what it costs. For additions, this initial conversation includes a discussion of zoning, setbacks, and any site constraints before design work begins.

Design and engineering – our architect and engineer develop the drawings, working through your goals and the constraints of your site and existing structure. This phase produces the permitted construction documents. Our designer works with you on material selections and exterior finish decisions during this phase as well.

Permitting – we submit for permits and manage the process through approval. Permit timelines vary by township and are built into the project schedule from the start so there are no surprises.

Construction – foundation, framing, roofing, exterior, rough mechanical work, insulation, drywall, and interior finish in the right sequence. Our crew stays on the project from start to finish. If something unexpected comes up during construction we tell you immediately and discuss how to handle it before proceeding.

Final inspections and walkthrough – we schedule and coordinate final inspections, complete any remaining items, and walk through the finished addition with you before we consider the job done.

Home additions require a contractor who can manage the full scope of what the project involves — not just the visible finish work. We’ve built additions ranging from 300 to 1,500 square feet across southeastern Pennsylvania and parts of New Jersey, and we understand what these projects involve from the first engineering assessment through the final inspection.

Having our architect, engineer, and designer in-house means the project moves as one coordinated effort rather than a handoff chain between separate professionals. Homeowners consistently tell us the process was more organized and less stressful than they expected — not because additions are simple, but because we planned them properly before construction began.

How long does a home addition take? Most home additions take two to four months from permit approval to completion. Larger or more complex projects — second-story additions, additions with significant structural work, or projects with longer permit timelines — can run longer. We give you a realistic schedule during the planning phase based on your specific project.

What affects the cost of a home addition? The main factors are square footage, project type, structural complexity, finish level, and mechanical scope. A straightforward single-room ground-floor addition is a different budget than a second-story addition or a project with significant structural work. We provide a detailed written estimate so you know exactly what’s included before any work begins.

Do you handle the design and engineering, or do I need to hire those separately? We handle both in-house. Our team includes an architect, a structural engineer, and a designer, so you don’t need to hire and coordinate those professionals separately before coming to us. We manage the full process from initial design through permitted construction.

Do you build second-story additions? Yes. Second-story additions require engineering assessment of the existing first-floor structure before design begins, since the existing foundation and framing have to support the new load. We evaluate this as part of our planning process.

Can you add a garage? Yes. We build both attached and detached garage additions. These projects involve their own foundation, framing, and permitting requirements, and we manage all of it.

Why can older homes add complexity to an addition project? Older homes in Bucks County and Montgomery County often have existing conditions — framing that doesn’t meet current standards, foundations with settling history, mechanical systems near or at capacity — that affect how new construction ties in. We assess all of this during planning so it’s accounted for in the scope and budget before work begins.

What should I think through before reaching out for an estimate? The most useful things to have in mind are how you want to use the new space, roughly how large it needs to be, and whether there are any obvious site constraints like grade changes, mature trees, or neighboring structures. We work through the rest together during the planning process.
