How we design and build homes

Before we draw a thing, you get a written analysis of your lot to keep. Then one team based in Southport designs your home and builds it.

The Tropical Tides standard

Built to the physics of the coast.

Salt air eats fasteners. Humidity finds cold surfaces. Wind finds the weakest connection in the load path. A coastal home has to answer all three before it answers anything about style, and that order is the whole standard.

Wind

Every home we design pursues FORTIFIED Gold, the top designation from the Insurance Institute for Business & Home Safety. An independent evaluator inspects the roof, the openings and the load path tying them to the foundation before IBHS issues it.

Air and Moisture

The airtightness target is sub-1.0 ACH50. North Carolina's residential code accepts up to 5 when a house is tested, and the tighter number decides where humid air gets into the walls.

Salt and Sun

Fasteners, hardware, flashing and cladding are specified for coastal exposure, and assemblies are detailed to drain, dry and stay open to inspection for the life of the house.

The Code as the Floor

The 2018 North Carolina Residential Code sets the minimum. Here that means design wind speeds of 130 to 150 mph, in a climate the code marks warm-humid in all three counties.

FORTIFIED Gold and sub-1.0 ACH50 are design targets, written into every set of drawings we produce. The designation and the blower-door number are confirmed house by house as each is built and tested, so the results grow as projects complete. Many insurers recognize FORTIFIED, and your agent can tell you how yours treats it.

The high-performance page goes system by system through airtightness, moisture, mechanical design and durability, and why coastal homes need a different standard makes the longer case.

Our process

Our design-build process runs in six steps.

The order matters. A floor plan drawn before anyone knows the required flood elevation gets drawn twice, and a price set before the house is understood gets set twice. Each step produces something you can read before the next one begins.

Step 01

Discovery and Fit

We talk through the lot, your budget and timeline, how you live, and what you expect the house to do. If we are the wrong fit for the project, we say so early.

Step 02

Formal Site Analysis

A site visit, then a written analysis of the lot: flood zone, wind exposure, orientation, shade and views, and any regulatory or historic constraint. You receive it as a document.

Step 03

Concept Design

Massing, plan direction and the character of the exterior develop together, drawn against the site analysis, with an early performance strategy beside them.

Step 04

Design Development

Plans, assemblies, materials and systems get specific, and cost is estimated as the design develops so the drawings stay inside your budget.

Step 05

Documentation

Coordinated drawings, specifications and engineering become a permit-ready set that a crew can build from without guessing.

Step 06

Build

We direct construction on site. Vetted trade partners build to the drawings, and the performance targets are checked as the house goes up.

The site analysis is yours to keep.

Much of what decides a coastal house is settled by the ground: how high the first floor has to sit, which way the weather arrives, and what the setbacks and overlays leave room for. The formal site analysis puts those facts in writing before a room is drawn. It is usually the first piece of work we scope, it goes into your client workspace when it is delivered, and you keep it whatever you decide next.

  • Flood zone classification and the elevation the lowest floor has to reach
  • Wind exposure category and the design wind speed for the lot
  • Orientation, sun path and shade
  • View corridors
  • Setbacks, utilities and drainage
  • Any historic or regulatory constraint on the parcel

Those facts change from town to town more than most people expect. Freeboard, the wind line, CAMA review and the office that issues the permit are laid out community by community on our custom new home construction page.

Renovations and ADUs follow the same six steps.

On a home renovation or addition, an assessment of the existing house stands in for the site analysis: existing conditions, structure, moisture and the permit path, written down before any scope is priced. An accessory dwelling unit starts with what the lot and the town allow, since the rules for a second dwelling vary from one community to the next.

Design-build

Design-build keeps one team answerable for the whole house.

There are two common ways to get a custom home built. An architect draws it and a separate builder prices and builds it, or a local contractor who does custom homes takes it on from experience. Both produce good houses. Design-build puts the drawing and the building with one team, and that changes who answers for the result.

Where things get lost

With an architect and a separate builder, the design is usually finished before the people pricing it are involved. When a bid comes in over budget, the performance details are the easiest things to cut, because they never show up on a rendering: the air barrier, the flashing sequence, the hardware rated for salt. The client holds two contracts and carries questions between them.

A local contractor who does custom homes knows the coast and the trades, and has often built a lot of houses. What tends to be missing is design leadership, a formal site analysis and a structured way to keep the client informed, so the client spends the project chasing phone calls and status updates.

What design-build changes

Here, the people who design the house also estimate its cost and direct its construction. Cost is checked while the design develops, so a budget problem arrives as a design decision you can weigh, at a point where moving a line on paper costs little. The performance targets are written into the drawings the trade partners build from, and a substitution on site is decided and recorded with its reasoning.

One team answers for the house, from the site analysis to the blower-door test.

Partners and collaborators

Vetted trade partners build the house under our direction.

A fair question for any builder is who will actually be working on your lot. Tropical Tides designs the house and directs its construction. Trade partners do the work on site, selected for each project and building to the drawings they were given.

Chosen for Coastal Work

Partners are vetted for coastal experience, the quality of their work, how they document it and how they communicate.

Scope in Writing

Drawings, specifications and the decision record settle what gets built before anyone prices it or picks up a tool.

Checked While Visible

Foundations, connections, the air barrier and the flashing are inspected while they can still be seen, and the blower door runs at the end.

One Point of Contact

You deal with Tropical Tides from start to finish. The partners answer to us, and we answer to you.

Construction runs under NC Residential Contractor License #109520, and we are members of the Brunswick County Home Builders Association. Southport is our home base, and you can reach us at 910-946-5512.

Client workspace

Every decision is written down with the reason behind it.

Building a custom home can mean months of chasing answers: what was decided, what it cost, what happens next. Every client gets a private workspace that holds those answers, from onboarding through handover.

Documents

The site analysis, the current drawings, and permits and approvals as they arrive.

Decisions

Each decision with its reasoning and its date, so a choice made months ago can still be traced.

Selections

Finishes, fixtures and materials, chosen and kept together in one place.

Build Schedule

The phases of construction as they are published, so you can see what comes next.

You can preview the client workspace before you start. The team publishes into it on a steady cadence, so what you see there is current.

Calm and informed, from the first session to the keys.

Design philosophy

Coastal houses should look calm and age well.

Clear plans, durable materials and restraint in the details. A house that feels effortless usually means somebody did the hard thinking on paper, early, while changes were still cheap.

Restraint

Fewer gestures, better proportions, cleaner rooms, and details that still look right decades on.

The Site Leads

Sun, wind, water, neighbors and the approach to the lot shape the plan from the first sketch.

Performance You Can See

Diagrams, targets and plain-language decisions explain the systems hidden inside the walls.

Made for Daily Life

Materials chosen for how they look after a decade of salt air, and rooms planned around how you live.

Style follows from those. A raised house on an oceanfront lot, a cottage on an in-town grid and a farmhouse on inland acreage should each look as if it belongs where it stands, and each answers to its own flood zone, wind exposure and neighbors.

Our team

The team stays small on purpose.

Design leadership and project direction stay in-house. Engineers, building-science consultants and trade partners join by project, chosen for what that house needs. You should always be able to name the person thinking about your house.

Design Lead

Sets the architectural direction, guides you through design and carries the documentation to a permit-ready set.

Engineers

Structural and specialty engineers join where the lot and the design call for them, and their work goes into the permit set.

Performance Advisors

Mechanical, envelope and building-science collaborators help set the targets and coordinate the systems that meet them.

Trade Partners

The crews on site, each on its own scope, working to the drawings under our direction.

Our story

Tropical Tides starts with the parts of a house nobody sees.

Coastal homes tend to be sold on how they look. Whether they last comes down to parts hidden once the walls close: the load path, the air barrier, the flashing behind the cladding. Tropical Tides began in Southport to design and build around those parts first, and to let clients see the work as it happens.

Why Homes

A coastal home is where daily life, risk, climate, money and memory all meet.

Why Performance

On this coast, durability and comfort are design decisions, made early or made expensively.

Why Clarity

Plans, decisions and a schedule you can see keep a long project calm and informed.

Tropical Tides is in its first chapter. The design work, the targets and the reasoning behind them are written up in our insights as the work happens, including how a tight house still gets fresh air and planning for moisture before it appears. Measured results join them as projects are completed and tested.

Common questions

Questions about how we work

What is a design-build home builder?
A design-build builder takes a house from design through construction with one team. The other common route is hiring an architect for the drawings and a separate contractor to build from them. At Tropical Tides the site analysis, design, documentation and construction run as one process, with cost estimated while the design develops and the performance targets carried from the drawings to the blower-door test.
What are the steps to building a custom home on the North Carolina coast?
Ours runs in six: discovery and fit, a formal site analysis, concept design, design development, documentation, and the build. The site analysis comes before any drawing, because the flood zone, wind exposure and setbacks decide how high the house sits, how it is framed and where it fits on the lot. The permit application follows the documentation step, and which office issues the permit depends on the town.
What does a site analysis include before designing a house?
Ours is a written document based on a site visit. It records the flood zone classification, wind exposure category, lot orientation, shade and view corridors, setbacks, utilities and drainage, and any historic or regulatory constraint on the parcel. It is delivered before design begins, it goes into your client workspace, and you keep it whether we go on to build the house or not.
What is FORTIFIED Gold?
FORTIFIED is a construction standard from the Insurance Institute for Business & Home Safety (IBHS), and Gold is its highest designation. It covers the roof, the windows and doors, and a continuous load path connecting the roof to the foundation. An independent evaluator inspects the work before IBHS issues the designation. Every home we design pursues it, and many insurers recognize it.
What does sub-1.0 ACH50 mean?
ACH50 measures airtightness: how many times the air inside a house is exchanged in an hour while a blower door holds it at 50 pascals of pressure. North Carolina's residential code accepts up to 5 when a house is tested. Our design target is under 1.0, so humid coastal air comes in through a ventilation system sized for the house. It is confirmed by blower-door test before handover.
Does Tropical Tides use subcontractors to build the house?
Yes. Vetted trade partners build it under Tropical Tides' direction, each on a written scope drawn from the drawings and specifications. We coordinate them on site, inspect the work at the points that matter while it is still visible, and stay your single point of contact throughout. Construction runs under NC Residential Contractor License #109520.
Can you look at a lot before I buy it?
Yes. Send the address or parcel number and what you hope to build. The formal site analysis is usually the first piece of work we scope, and it answers the questions that decide whether a lot suits the house: the flood zone and required elevation, wind exposure, setbacks and any overlay, and how the lot sits to sun and view.
Where does Tropical Tides build?
Across Brunswick, New Hanover and Pender Counties in coastal North Carolina, from our base in Southport. That takes in the island towns from Sunset Beach to Topsail Beach, Wilmington and its neighbors, and inland communities such as Winnabow, Burgaw and Rocky Point. Each county page links a guide for every community we build in.
