Frequently Asked Questions

Architecture

What architectural services do you offer?

Full architectural services from site analysis through construction documents — schematic design, design development, construction documents, and construction administration. We design custom homes, additions, renovations, kitchens and baths, and light commercial.

Can I hire Longfellow for design only, without construction?

Our model is integrated design-build. We do not offer design-only services because the value we provide — cost certainty, schedule reliability, and design integrity — depends on the architect and builder being the same entity. If you are looking for design-only services, we are happy to refer you to design firms we respect.

Budget & Pricing

What does a custom home cost?

Custom home costs in our markets — Greater Boston, Cape Cod, New Hampshire, and Southwest Florida — typically range from $400 to $700+ per square foot, depending on site conditions, design complexity, material selections, and finish level. A 3,000 sq ft coastal home in Chatham will price differently than a 3,000 sq ft home in Weston. We provide detailed, transparent pricing at each phase of design so you're never surprised late in the process.

How do you handle budget overruns?

We work hard not to have them. Because our architects, engineers, and builders are integrated from the start, design decisions are evaluated against real construction costs throughout the design phase — not after the plans are complete. We use open-book pricing and flag budget pressure points early. When scope changes do happen (they always do), we price them transparently before proceeding.

Do you offer fixed-price contracts?

We offer guaranteed maximum price (GMP) contracts once design is complete and construction documents are finalized. At that point we have enough detail to price the project accurately and absorb the risk of cost fluctuations within the agreed scope. Changes to scope are priced separately as change orders.

Design

What architectural styles do you work in?

All of them, within reason. Shingle-style coastal homes are a large part of what we do on the Cape and South Shore. We also build Adirondack-influenced mountain lodges in New Hampshire, transitional homes in Metro West communities like Weston and Wellesley, and clean contemporary homes on the Outer Cape. What matters more than style is design quality and calibration to the site. We don't have a house we try to build repeatedly.

How involved can I be in the design process?

As involved as you want to be. Some clients come to us with a very specific vision and want to be in every design meeting. Others give us a general direction and trust us to develop the details. Both work. What we ask for from every client is honest feedback at each design milestone — it's much easier to change a floor plan in concept review than to change framing during construction.

Do you have a showroom where I can see materials?

Yes — we have showrooms in Falmouth and Boston that carry the material lines we use most: cabinetry, stone, tile, plumbing fixtures, and hardware. Seeing materials in person, holding them, and comparing them side by side makes a real difference in how confident clients feel about their selections.

Engineering

Why does it matter that you have in-house engineers?

Most residential builders outsource their engineering. The architect draws the plans, emails them to an outside structural engineer, waits a week or two for calculations, and iterates through revisions over email. That engineer has never met you and has no stake in keeping your budget in check. Our structural and civil engineers sit in our offices, attend design meetings, and walk job sites. When a field condition requires an engineering decision, it gets made the same day — not two weeks later.

Why does Longfellow have in-house engineers?

Most residential builders outsource structural and civil engineering. We decided early on that having engineers in-house — attending design meetings, walking job sites, answering questions in real time — produces better buildings at lower cost. When an architect asks a structural question at 2pm, our engineer answers by 3pm. That speed compounds across a project.

Do you handle coastal and flood zone construction?

Yes — it's a significant part of our practice. Elevated foundations for FEMA flood zones, wind-resistant framing that meets or exceeds hurricane ratings, corrosion-resistant connections for salt-air exposure. Our civil engineers also navigate the conservation commission and wetland setback requirements specific to each Cape Cod and South Shore community we work in.

What does your structural engineering team cover?

Load analysis, foundation design, framing systems, beam and column sizing, lateral load systems, and construction-phase observation. We handle new construction and renovation, residential and light commercial.

What does your civil engineering team handle?

Site grading, drainage design, stormwater management, septic system engineering, and permitting with state and local environmental agencies. Our civil team has navigated these processes across Cape Cod, the South Shore, the North Shore, and Southwest Florida.

General

Do you do renovations as well as new construction?

Roughly half our work is renovation — additions, gut renovations, kitchen and bath remodels. Our structural engineering team is especially useful for renovation projects where structural changes are required.

What is your minimum project size?

We do not publish a hard minimum, but as a general guideline our construction work starts around $500,000. Below that threshold, our overhead structure is not competitive with smaller contractors. For design-only scope, we work at a wider range of project sizes.

How do I get started?

Contact us through the form on this site or call our main office. We will schedule an initial conversation — no fee, no obligation — to understand your project and determine whether we are a good fit. If we are, we will propose a discovery and schematic design engagement to get your project started.

Process

What does "design-build" mean, and why does it matter?

Design-build means one firm handles architecture, engineering, and construction — all under the same roof. The alternative is hiring an architect separately, then putting the project out to bid, then managing the relationship between two companies that may have never worked together. With design-build, your architect and builder are on the same team from day one. Design decisions get immediate construction feedback. Engineering happens in real time. Change orders shrink because the team that drew the plans is the team building them.

How long does a custom home take from design to move-in?

Typically 18–30 months from first meeting to move-in, depending on project size and complexity. Design and permitting run 6–12 months. Construction runs 12–18 months for a new custom home. Renovations are shorter. We give you a detailed schedule at the end of schematic design so you know what to expect.

How do I start a project with Longfellow?

The first step is a conversation — no commitment, no fee. We meet at your site or in one of our showrooms, talk about what you're hoping to build, and assess whether the project is a fit for what we do. If it is, we'll walk you through our process, timeline, and how we approach initial design and budgeting. From there, we move into a formal design agreement.

What is the advantage of design-build vs. hiring separately?

In traditional delivery, your architect and contractor have separate contracts and separate interests. Coordination gaps between them are one of the primary causes of budget overruns and schedule delays. Our model puts the architect, engineer, and construction manager on the same team from day one — one contract, one chain of accountability. The result is a home that gets built the way it was designed.

Do you handle permitting?

Yes. We manage the full permitting process — architectural submissions, engineering sign-offs, conservation commission filings where required, and coordination with the building department. You do not need to interact with any town office directly unless you want to.

Can I bring my own architect or plans?

We can work from plans prepared by an outside architect, though we'll need to review them with our engineering team before committing to a construction scope and price. In most cases, clients who come to us early in the design phase get better outcomes — both on cost and design quality — because our engineers and builders are shaping the plans from the start rather than inheriting decisions made without that input.

How does pricing work?

We provide a detailed cost estimate at the end of schematic design, before you commit to construction documents. That estimate is built line by line by our construction managers — not a rule-of-thumb number. We price what we have drawn, so there are no surprises when you go to contract.

Service Areas

Where do you build?

Greater Boston, the South Shore, the North Shore, Cape Cod (all towns), and Southwest Florida (Naples, Sarasota, Captiva). We also have an active practice in southern New Hampshire around Lincoln and the Lakes Region.

Do you work outside your primary markets?

Occasionally, for the right project. If you are outside our primary markets, contact us and we will tell you honestly whether the project is a fit.

Timeline

How long does a custom home take from start to finish?

A typical custom home takes 18–30 months from initial design through move-in. Design, engineering, and permitting generally takes 6–12 months depending on project complexity and municipal review timelines. Construction typically runs 12–18 months. Renovation projects and additions move faster — a major kitchen renovation might be 3–6 months from design to completion.

What factors can affect the project timeline?

Permitting is the biggest variable we don't fully control — conservation commission reviews and zoning variances can add months in certain Cape Cod and coastal communities. Lead times on specialty materials (custom windows, stone, cabinetry) also affect scheduling and need to be anticipated early. Weather is a factor on new construction sites. We build detailed schedules that account for these variables and update them throughout the project.
