Melba is a small farming community in south Canyon County, above the Snake River and well outside the subdivision belt. Almost everything we build here is on acreage, and almost all of it involves a well, a septic system, and an irrigation easement.
Custom homes, farmhouse renovations, shops, equipment buildings, and detached garages make up most of our work in this part of the valley.

What we find in Melba homes
Melba’s housing is predominantly rural — farmhouses ranging from early-twentieth-century through mid-century, manufactured homes on acreage, and a modest number of newer custom builds on parcels bought for the space and the view. Older farmhouses here typically need comprehensive systems work: service upgrades, plumbing replacement, insulation and air sealing, window replacement, and structural review of additions and porches that were framed informally. Existing outbuildings are common and are often worth replacing rather than repairing once you price them honestly.
Permitting and planning in Melba
The City of Melba covers the small townsite; nearly everything beyond it falls to Canyon County Development Services, which sets the standards for dwellings, accessory structures, setbacks, and lot coverage. Rural parcels here run on private wells and septic systems requiring Southwest District Health approval, and irrigation district easements and delivery ditches cross most of the farmland. Power service distance and legal access are real budget items on parcels set well back from the road, and both should be established before a house plan is chosen.

Learn moreBuilding in Melba: common questions
What does it take to build a house on Melba acreage?
Beyond the house: a drilled well, a septic system with district health approval, power service to the site, driveway and approach permitting, and confirmation of irrigation easements and any delivery obligation attached to the parcel. We scope and price those at the start, because they can move the total meaningfully.
Do you build equipment and hay storage buildings?
Yes — post-frame and steel buildings for equipment, hay, and shop use are regular work out here. Span, clear height, door sizing, and whether you intend to insulate and heat it are what drive the structural approach.
Is it worth renovating an old farmhouse or better to build new?
It genuinely depends on the foundation, the framing, and how much of the original house you want to keep. We will walk it and give you an honest answer with real numbers on both paths, including the cases where the answer is that renovation does not pencil.

“The finished work was excellent, delivered on time, and inside our budget. What more is there to ask?”
Our experience with GW Construction was outstanding from beginning to end. They were recommended to us by a real estate agent we trusted, who was helping us plan a remodel of a home we had just purchased. Past contractors had been hit or miss for us, so committing to a renovation north of $70,000 made us genuinely nervous. That changed at the first meeting. Derek listened carefully to what we wanted the remodel to accomplish and then carried the plan out faithfully. Just as valuable, he offered real insight where he saw a way to improve on our thinking, and told us plainly when an idea of ours was not economically sensible or carried a downside we had not considered. He was straightforward, transparent, and respectful throughout. Communication was excellent — calls, emails, and texts were returned promptly. He even introduced us to each of the subcontractors so we could build a relationship with them directly. Most importantly, the finished work was excellent, delivered on time, and inside our budget. What more is there to ask? Highly recommended.
Jack and Sue Serrino“He has completed more than 25 projects for my clients over the years, and I intend to keep sending them his way.”
Derek is far and away the best contractor I have worked with, and his ability to listen to my clients and respond to what they actually need has exceeded anything I expected. Being classically trained and professionally educated shows in the work. His grasp of both the practical and the possible means he handles small and large-scale jobs equally well, and there is genuinely nothing I would hesitate to refer to him. He has completed more than 25 projects for my clients over the years, and I intend to keep sending them his way.
