Is It Cheaper to Tear Down or Remodel a 1980s West Lake Hills House?
Published November 2, 2026
Whether it is cheaper to tear down or renovate your 1980s house in West Lake Hills mostly depends on the foundation, frame and roof. A whole-house remodel keeps those parts, so have them inspected first. For a whole-house remodel, RenovatePros' own published estimates run $100,000 to $500,000 per project. Those are general estimates, not West Lake Hills prices, and they set no house size. NAHB's 2024 builder survey puts the national average construction cost of a new house at $428,215 for 2,647 sq ft. The NAHB figure is construction cost only, and NAHB lists the lot separately. Fixr's national range to tear down a house is $7,500 to $15,000, priced apart from building. These figures measure different things, so do not compare them dollar for dollar.
What does a whole-house remodel cost?
A whole-house remodel costs $100,000 to $500,000 per project in RenovatePros' published estimates, split into three tiers. The tiers are general estimates, not a quote and not a West Lake Hills price. Your home's size and your scope set your real number.
| Tier | Estimated cost per project |
|---|---|
| Tier 1 | $100,000 to $150,000 |
| Tier 2 | $150,001 to $250,000 |
| Tier 3 | $250,001 to $500,000 |
Where your remodel lands depends on how much of the house you change. Cosmetic work, such as paint and floors, costs less than moving walls, rewiring or replumbing. You can see the same three tiers on the whole-home renovation service page. For what moves your price up or down the range, read what a whole-house remodel costs in Austin.
What does building a new house cost, and what does demolition add?
Building a new house cost a national average of $428,215 in NAHB's 2024 builder survey. That price is for a house with 2,647 sq ft of finished space. The NAHB figure is construction cost only. NAHB lists the finished lot as a separate cost, and on a teardown you already own your lot. The survey is national and covers a group of NAHB builders, so the $428,215 is not a West Lake Hills price.
Demolition is a separate cost on top of building. Fixr's national range to tear down a house is $7,500 to $15,000, in a cost guide updated January 31, 2025. Fixr also notes that asbestos in siding, roofing, flooring or insulation can make demolition two to three times more expensive.
No national survey can tell you what a new house on your West Lake Hills lot will cost. Your lot's slope, trees and drainage all shape the plans. Only a builder's quote for your lot and your plans gives you that number.
When does tearing down make more sense than remodeling?
Tearing down a 1980s West Lake Hills house makes more sense when the parts a remodel would keep are not sound. Before you choose, have a structural engineer or a home inspector check these five things:
- The foundation: cracks, movement or settling.
- The frame: rot, termite damage or walls that lean.
- The roof: sagging, leaks or water damage in the structure.
- Moisture: signs of long-term leaks or mold inside the walls.
- The wiring and pipes: systems that cannot be brought up to code.
Foundations made up 10.5% of construction cost in NAHB's 2024 builder survey, a national figure. Framing made up 16.6% of construction cost in the same national survey. A remodel that keeps your sound foundation and frame does not pay to build them again. If your inspection says the foundation or frame has to be replaced anyway, a remodel loses much of its head start.
Can we keep the shell and add a second story or an addition instead?
Yes, you can keep the shell of a 1980s West Lake Hills house and add a second story or an addition when the foundation and frame pass inspection. That middle path sits between a remodel and a teardown. You keep the foundation and frame that pass inspection. You remodel the inside and build the space you are missing. A second story adds weight, so ask an engineer whether your foundation and lower walls can carry it. An addition on the ground grows the footprint, so check the trees and drainage on that side of your lot first. You can see how a build-up works on the second-story additions page. The price of an addition depends on its design, so you get it from an itemized quote.
Should we remodel, add on, or tear down?
Remodel your 1980s West Lake Hills house when the foundation, frame and roof are sound and the layout works for you. Add on when the structure is sound but you need more room. Tear down when your inspection shows the foundation or frame has to be replaced. Here is how the three paths compare:
| Path | What you keep | What gets rebuilt | Permits and steps in West Lake Hills | What to inspect first |
|---|---|---|---|---|
| Whole-house remodel | Foundation, frame and roof | Inside finishes, plus wiring, pipes and HVAC as needed | Residential development permit for a remodel | Foundation, frame, roof, wiring and pipes |
| Keep the shell and add on | Foundation and frame of the house you have | The inside, plus the new second story or addition | Residential development permit for an addition; tree permit if trees come out | Whether the foundation and walls can carry new weight; trees and drainage near the new space |
| Tear down and rebuild | The lot | The whole house | Demolition permit, then a residential development permit for new construction; tree or floodplain permit first if either applies | Trees, drainage, setbacks and the impervious cover limit for your lot |
What permits does a teardown need in West Lake Hills?
A teardown in West Lake Hills needs a demolition permit from the City of West Lake Hills. Your new house then needs a residential development permit. First, confirm that your address is inside City of West Lake Hills limits, because these city forms only apply there.
The City of West Lake Hills demolition permit form, dated February 2021, lists these items:
- A $50,000 surety bond in the city's name
- A $100 application fee for a residential demolition
- General Contractor Registration with the city for projects of $25,000 or more
- Proof of liability insurance of at least $600,000
- A survey or site plan showing what is on the lot and the setbacks
- A tree and topo survey
- A dumpster location and a route for the debris
The same demolition form says a tree permit comes first if regulated trees will be removed. A floodplain permit comes first if your lot is in a FEMA floodplain.
Your new house then goes through the city's Residential Development permit form, dated March 2020. You file it through the city's MGO Connect portal. The form asks for a drainage report, a RESCheck energy report, a tree and topo survey, a survey showing setbacks, and your total impervious cover. Impervious cover means hard surfaces that rain cannot soak through, such as roofs and driveways. The city's 2026 Drainage and Erosion Control Design Manual took effect on May 18, 2026. Fees and forms can change, so confirm current requirements with the City of West Lake Hills before you plan. For how the city's rules touch a remodel, see whole-home renovation in West Lake Hills.
Will a rebuild keep what the old house was allowed?
Whether a rebuilt West Lake Hills house keeps what the old house was allowed is a question for the City of West Lake Hills. Do not assume the answer either way. An older house may sit closer to a lot line, or cover more of the lot, than you could build new today. Before you tear down, ask the city for a written answer on the impervious cover and setbacks for your lot. That answer tells you how big your new house can be. It can also decide whether a teardown still makes sense for you.
What about the 1980s wiring and pipes?
The wiring and pipes in a 1980s West Lake Hills house matter on every path, because a whole-house remodel opens the walls where they run. Rewiring a 1980s house is its own cost question, and an electrician's inspection tells you what yours needs. If you are not sure what your water pipes are made of, including whether any are polybutylene, ask a plumber to check them.
Where do you start with a 1980s West Lake Hills house?
Start your 1980s West Lake Hills project with an inspection of the foundation, frame and roof. Then get an itemized quote for each path you are weighing. An itemized quote shows what each number covers, so you can see what a lower bid leaves out. Because RenovatePros does whole-home remodels, additions and second stories, one team can price the remodel and add-on paths side by side. One homeowner, Emily Hester G., wrote of Daniel, the owner: "It never felt like he was trying to sell us on anything." You work directly with the owner on site, with no sales reps.

Frequently asked questions
Is it cheaper to tear down or renovate?
Whether it is cheaper to tear down or renovate your 1980s West Lake Hills house depends on whether the foundation, frame and roof are sound, because a remodel keeps them. RenovatePros' published whole-house remodel estimates run $100,000 to $500,000 per project, as general estimates. NAHB's 2024 builder survey puts the national average construction cost of a new house at $428,215 for 2,647 sq ft. Fixr's national range to tear down a house is $7,500 to $15,000.
Renovation vs knock down and rebuild: which fits an older house?
Renovation fits an older house when an engineer or inspector finds your foundation, frame and roof sound, because a remodel keeps them. A knock-down and rebuild fits when the foundation or frame has to be replaced anyway. In West Lake Hills, ask the city for a written answer on impervious cover and setbacks for your lot before you plan a rebuild.
What does a remodel cost compared with tearing down and rebuilding?
A whole-house remodel runs $100,000 to $500,000 per project in RenovatePros' published estimates, which are general and not West Lake Hills prices. A new house cost a national average of $428,215 in construction cost for 2,647 sq ft in NAHB's 2024 builder survey, with the lot listed separately. Fixr's national range to tear down a house, a separate cost, is $7,500 to $15,000. These figures measure different things, so do not compare them dollar for dollar.
Can we keep the house and add a second story instead?
You can keep your 1980s West Lake Hills house and add a second story when the foundation and frame pass inspection. Ask an engineer whether your foundation and lower walls can carry the new weight. The price of a second story depends on its design, so you get it from an itemized quote.
What does it cost to rewire a 1980s house during the remodel?
Rewiring a house costs $6 to $10 per sq ft in SoFi Learn's national figures, published January 30, 2026. SoFi's own example puts a 2,500 sq ft house at about $15,000 to $25,000. Those are national figures, not West Lake Hills prices, and an electrician's inspection tells you what your house needs.
Does the wiring in a 1980s house have to be replaced during a remodel?
Whether the wiring in your 1980s house has to be replaced during a remodel is for an electrician's inspection to decide. No single rule covers every house. Rewiring is easier when a whole-house remodel already has your walls open.
