Custom Home Building & Major Remodeling Projects on the Central Coast

From First Sketch to Final Nail — One Trusted Team.

Based in Templeton, Gannage Design & Construction helps homeowners across California’s Central Coast plan and build major remodeling and custom home projects. For over 30 years, our team has handled complex remodels, additions, and design-build work that require clear planning and experienced oversight. We guide each project from early design through final construction so homeowners know what’s happening, what it costs, and what to expect at every step.

We provide full-service design-build construction — and we support homeowners who need guidance, clarity, or professional oversight as they navigate their own projects.

Whether we’re building it for you or guiding you to build it yourself, our objective is the same: to bring our experience to honest, frank discussions, informed decision-making, and choices that stand the test of time.

How We Help

There’s More Than One Right Way to Accomplish What You Need.

Every project is different — and so is every homeowner. We help you choose the level of support that actually fits your goals, timeline, and budget.

Design Services

Where Strong Projects Begin.

Most costly mistakes in construction happen before construction ever starts.

Pre-construction is the phase where scope is clarified, feasibility is tested, documentation is prepared, and decisions are aligned before trades are hired or money is committed.

Some homeowners choose to handle portions of this work themselves to reduce upfront cost. That’s completely reasonable. But it’s important to understand what’s involved — because if these tasks aren’t handled thoroughly, the cost usually shows up later in the form of delays, confusion, or change orders.

You can take this on. Or we can support you through it!

Core Components

Turning early ideas into a buildable direction.

This answers: Is this realistic? What are the trade-offs?

Construction Documents

Translating the concept into detailed, permit-ready plans.

Clear documentation protects both the budget and expectations.

Construction Guidance

Your Vision, Streamlined.

Pre-Construction Management

For homeowners who want structure and professional guidance while remaining actively involved.

We bring clarity before construction begins — defining a written scope of work, coordinating subcontractor bids, preparing a preliminary schedule, and reviewing contracts to ensure alignment before anything is signed.

Our role is to help you understand what you’re agreeing to, identify gaps early, and prevent costly misunderstandings before they become expensive change orders.
This is about thoughtful preparation — so your investment supports your family’s long-term goals, not short-term confusion.

Construction Management

If managing active construction feels overwhelming, we provide professional oversight and structured coordination throughout the build.

We conduct site visits, review subcontractor work against agreed scope, align invoices with actual progress, and monitor change orders for accuracy and accountability.

Our role is not to replace your subcontractors — but to advocate for you, ensuring commitments are honored and that additional charges reflect legitimate scope changes, not preventable oversights.

This approach brings commercial-level organization and accountability into the residential space — protecting your investment while keeping the project moving forward.

Stand-Alone Services:

Design-Build Construction

From Dream To Reality.

From early planning through construction completion, we manage the entire process — design, budgeting, permitting, and execution — with one integrated, accountable team.

This path is ideal for homeowners who want a guided, comprehensive experience and a single point of responsibility and liability from start to finish.

Additional Support
(When It Makes Sense)

These Tasks Are Part of Most Successful Projects. If You Prefer to Manage Them Yourself, You Can. If Not, We’re Here to Help!

Selection Management

Selection Management goes far beyond choosing a faucet.
It includes baseboard profiles, drywall texture and corner details, window styles, and the dozens of finish decisions that shape how your home ultimately feels.

Whether we’re working directly with you or coordinating with your interior designer, we identify every required selection early, guide you through decisions in a logical sequence, track them carefully, and help align choices with your overall budget.

Feasibility Studies

Zoning regulations, utility locations, required setbacks, site access, and existing structural conditions all influence what can be built and where. This is particularly critical for additions and ADUs, where property lines, infrastructure, and load paths can quickly become limiting factors. We assess these constraints upfront so design decisions are grounded in reality, avoiding costly revisions later in the process.

Permit Processing (Owner’s Agent)

We coordinate submittals, manage revisions, and navigate agency responses on your behalf while you remain the legal permit holder. You stay in control, we handle the complexity.

Not Sure Where You Fit?

A Conversation Can Help Clarify That.

Whether you’re early in the process or already navigating a project, we’re happy to help you think things through.

NICK RECTOR

Project Manager

Nick joined the Gannage Design & Construction team in February 2023 as our Construction Superintendent after deciding that owning and operating his own construction company kept him behind a computer when where he excelled was in connecting with people. Nick spends most of his work day in the field with clients, contractors, and our team ensuring the project stays on track as intended.

From a young age, Nick fell in love with construction while helping his father and grandfather build their family home. In high school, Nick completed Architecture I, II, and III in addition to college-level math courses in preparation for making a career out of his passion. Nick’s passion for architecture and construction took a backseat, however, after he ran the mile in 4:23, which earned him a college scholarship in Track & Field and Cross Country. His focus, determination, and dedication saw him run in seven Nation Championships, finishing as high as 8th in the nation in Cross Country and Top 10 two times in the 5k and 10k track events. Post collegiately; Nick ran numerous half marathons, three marathons, and two 50ks before landing a job as Race Director and Event Director, where he honed his organizational and project management skills.

In 2016 Nick decided to return to his childhood love and dedicated himself to learning the trades. In 2019 he started his own construction company and successfully navigated the COVID pandemic with continued business growth. Ultimately Nick realized his passion was in the progress of the project, educating clients and crews and managing schedules, not business management, and we are eternally grateful as he has been a tremendous asset to the Gannage Design & Construction team from day one.

MIKHAIL GANNAGE

Founder | Master-Builder | Construction Strategist

Mikhail leads construction operations with a steady, methodical approach grounded in more than 30 years of field experience. He brings structure to complex builds — balancing craftsmanship with logistics, timelines, sequencing, and team coordination.

His leadership style is disciplined but approachable. Clients consistently note his willingness to listen — to create space for questions, to slow down decisions when needed, and to ensure they fully understand the implications of what they’re choosing. Construction can feel overwhelming; Mikhail’s job is to bring clarity and confidence to the process.

He believes strong process protects everyone involved: clients, trades, and the integrity of the finished work. Clear expectations, proactive communication, and real-time problem-solving are not extras — they are requirements.

Mikhail also brings a deeply vetted network of subcontractors and trades who share his standards and values. He does not simply hand off scopes of work; he communicates the full vision of the project so every trade understands how their piece fits into the whole. When even the underground plumbing crew understands the broader intent of the build, the result is better execution, stronger accountability, and greater pride in the outcome.

Leadership on a jobsite is not about control. It is about alignment — ensuring that the client’s vision is understood, protected, and carried through to completion with discipline and care.
