Custom Homes & New Construction

Building new in the South Bay almost always means a teardown and rebuild on a lot someone already owns. We take it from the demolition through the final inspection.

There is not much raw land left between San Jose and the hills, so most new construction here starts with an existing house coming down. A tired 1950s ranch on a good street in Willow Glen, Los Altos, Saratoga or Los Gatos is often worth less than the dirt under it, and rebuilding is how people get the house they want without leaving the neighborhood. That path runs through demolition, utility disconnects, soils work, survey and a complete drawing set before a single foundation form goes in. Hillside parcels above Los Gatos, Saratoga and Monte Sereno add grading, drainage and access to the list, and those costs show up early. We would rather walk the lot with you at the start and be blunt about what it is going to take.

Design review is a real part of building here. Palo Alto, Los Altos, Saratoga and Los Gatos all look closely at how a new house sits on its street, and neighbors pay attention. Getting through it comes down to a complete set of drawings, a design that respects the block, and someone who answers plan-check comments quickly instead of sitting on them. We have been licensed and building in Santa Clara County since 2007. Because we run our own carpentry shop, the cabinets, stair parts, built-ins and interior trim are made for the house rather than picked out of a catalog, which is usually where a custom home stops feeling like a spec house.

Why R Twyns Construction

We are a family-run licensed general contracting and remodeling company (CSLB #896811), building in the South Bay since 2007. Tim Reynolds owns the company and his VP Ben runs the work, so the people who price your job are the people who are on it. The cabinets and finish carpentry come out of our own shop, which is what an older house needs when nothing in it is square. And we tell you what a job actually involves before you commit to it — the load-bearing wall, the drain line, the permit — rather than after the walls are open.

Common questions

Is it better to remodel or tear down and rebuild?
It depends on what is worth keeping. If the foundation is sound, the roof lines work and you like the plan, remodeling usually wins. If you are re-plumbing, rewiring, raising ceilings, moving every wall and adding a second story anyway, you can reach a point where you are paying to preserve very little. We will walk the house and tell you where your project falls instead of steering you to the bigger job.
How do you handle design review in Palo Alto, Los Altos or Saratoga?
By taking it seriously from the start. Those cities look hard at how a new house meets the street and how it sits next to its neighbors, and a design that ignores that will burn months. We work with your architect to submit a complete set and we turn plan-check comments around quickly. We cannot promise an approval, and nobody honest will.
How do we know you are set up to build a whole house, not just remodel one?
Check the license class and the history. We are CSLB #896811 and have been building here since 2007. Pull the record, confirm the classification, the bond and the workers’ comp, and ask to see work in progress. A ground-up house is not the place to take someone at their word.
We bought a hillside lot above Saratoga. Does that change things?
Considerably. Sloped parcels bring soils work, grading, drainage, engineered foundations and often retaining walls, and the access itself becomes a cost — narrow roads, no staging area, and material that has to be moved in smaller loads. None of that is a reason not to build. It is a reason to price the site work honestly before you commit to a house size.
Can you work with our architect?
Yes, and we prefer to be in the conversation early. Coming in during design lets us flag what is going to be expensive to build while it is still cheap to change on paper. If you do not have an architect yet, we can point you to people we have worked with in this county.
