There is a particular moment at the start of a ground-up build that is hard to describe until you have stood in it. The old structure is gone. The lot is cleared. The dirt is fresh. Everything that was there is no longer there, and everything that will be there does not exist yet. It is the cleanest kind of blank slate there is.
That is where we are right now with our Las Flores project in Arcadia. A full tear-down, ground-up new home build on a lot that had been occupied by an older home for decades. The original structure is gone, the site is cleared, and we have broken ground on Phase 1: site work and trenching. The existing pool footprint is staying -- it will be rebuilt as part of the new design.
This is the first post in a series we’re going to run all the way through to the reveal. Every major milestone, start to finish. If you have ever wondered what a custom new home build actually looks like from the very beginning, this is it.
Why a Full Tear-Down?
When a homeowner approaches us about a major project, one of the first honest conversations we have is about whether to remodel or start from scratch. Most of the time, remodeling makes sense. But sometimes the existing structure is a genuine obstacle to what the homeowner wants to achieve. That is what happened here.
The original home had aging infrastructure, a layout that could not be reconfigured without significant structural work, and a footprint that did not use the lot efficiently. The pool footprint is being kept as part of the new design -- it will be rebuilt to match the vision for the new home.
This is not the right answer for every project, and we always run the numbers before making that recommendation. But when it is the right answer, a tear-down gives you something that no remodel can: a completely clean slate where every system, every wall, every window, every drain, and every wire is exactly where it should be, designed from the ground up for how this family is actually going to live in the space.
Demolishing the Old Pool
The pool footprint is being preserved as part of the overall design. It will be rebuilt to complement the new home -- a decision that made sense both structurally and for the long-term vision of the property.
There is no shortcut here that is worth taking. The foundation of the new home is going to tie into this area. If the soil is not properly compacted and prepared, you get differential settlement, and differential settlement in a foundation is not something you want to discover after the house is framed.
Site Cleared, Ground Broken
Once the lot was cleared, we moved into the early site work phase. Survey stakes went in to establish the exact setbacks and building envelope based on the approved plans. This is when the project starts to become real in a physical sense: you can walk the lot and see exactly where the walls are going to be, where the front entry faces, where the garage sits, where the backyard opens up.
Getting this right at the staking phase matters more than most people realize. Any error here carries forward into every subsequent phase of the build. Foundation forms, framing, utility rough-ins: everything references back to the original survey. We take our time at this stage, confirm everything against the plans, and verify with the city before we dig.
On a new build in California, the permit set is everything. Approved plans, soils report, energy compliance documentation, and utility coordination all have to be in order before a single shovel of dirt moves for structural purposes. The paperwork is not the fun part of construction, but it is what protects the homeowner and keeps the project moving without expensive surprises at inspection.
Trenching Underway
We are currently in the trenching phase. This is where the underground infrastructure goes in: sewer laterals, water service, electrical conduit, and gas service. Everything that will eventually be buried under concrete and inaccessible for the life of the building gets laid out, sloped, positioned, and inspected before the slab or foundation work covers it.
On this lot, sewer depth was something we scoped carefully before the project started. On a lot of this length, maintaining the required minimum grade to the city main while avoiding excessive depth at the house connection requires good planning up front. We ran the numbers, confirmed with the city, and the layout works cleanly. No surprises mid-trench, which is exactly how you want it to go.
This kind of pre-construction coordination is part of what separates a project that runs smoothly from one that hits expensive problems mid-stream. A lot of the planning work happens before the visible work starts. By the time you see activity on site, the hard decisions have already been made.
What Comes Next
With trenching underway, the next milestones in sequence are:
- Underground utility inspections and sign-off
- Rebar placement and footing forms
- Foundation concrete pour (one of the big milestone moments)
- Framing begins
We will document each of these phases here. The foundation pour especially is one of those days on a new build where you can feel the project shift from a plan into a permanent physical reality. That post will be worth watching for.
If you are thinking about a new build or major ground-up project in Arcadia or anywhere in the SGV, the planning phase is where the project is made or broken. Decisions made before the first shovel hits the dirt determine the budget, the timeline, and the quality of the finished product. That is true whether you are building a custom home, an ADU, or anything in between.

繁體中文摘要 — 從零開始：拉斯弗洛雷斯新建工程啟動
我們在阿凱迪亞（Arcadia）正式啟動一個全新的地基重建項目。原有建築已經拆除，舊游泳池已完成拆除清運，整塊地皮已清空，地基工程正式開工。這是這個項目系列的第一篇文章，我們將從頭到尾記錄整個建造過程。
為什麼選擇全拆重建？並非所有項目都適合全拆重建，但這個案例是正確的選擇。原有住宅基礎設施老化、格局無法有效改造，舊游泳池多年未使用且佔用了大量後院空間。從零開始，每一個系統、每一道牆、每根管線都可以按照屋主的實際需求重新規劃設計。
舊泳池拆除工程：舊地下泳池的拆除不是簡單填土。我們申請了許可證，按照規範破碎池體、切斷並封堵管線、清除碎料，再用工程填料分層壓實，確保回填土密實度符合建築要求。因為新建築的基礎會覆蓋這個區域，地基下方的土壤質量至關重要。
測量放線，正式破土：清地後，我們進行了精確的測量放線，確認建築紅線、退讓距離以及各功能區的位置。任何在這個階段的錯誤都會在後續所有施工階段累積放大，因此我們花了充分的時間核實，與城市審批部門確認後才開始動土。
地下管溝施工中：目前我們正在進行地下管線施工，包括污水側管、供水管、電氣導管和燃氣管道。所有地下管線必須在基礎混凝土澆築前鋪設完畢，通過驗收後才能覆蓋。我們提前核算了污水管坡度、與市政主管的連接深度，確保施工無意外。
下一步工程：地下管線驗收完成後，緊接著是鋼筋綁紮與基礎模板工程，然後是重要里程碑：基礎混凝土澆築。之後是結構框架開始。我們將持續記錄每個階段，請持續關注。
