Whole-Home Remodeling in the East End / Warm Springs
Period-respectful comprehensive renovation of East End bungalows and Warm Springs estates — full systems modernization, primary suite additions, original character preservation.
Quick answer
10–16 months for period-respectful renovation; 12–18 months for Craftsman bungalow comprehensive with primary suite addition; 14–20 months for down-to-studs; 14–22 months for Warm Springs mansion or two-story bungalow conversion. Pre-construction (design, engineering, HPC, permitting) is typically 7–10 months; construction is 7–12 months.
Whole-home remodeling in the East End and Warm Springs Avenue is among the most demanding work in Boise — comparable in complexity to North End historic district projects but with the specific overlay of geothermal heat integration, plaster-and-lath construction throughout, near-universal pre-1928 construction with attendant lead and asbestos requirements, and HPC review for any exterior modifications. The typical project: a 1900–1925 Craftsman bungalow or estate (or a Warm Springs Avenue Victorian) where original architectural character is the primary asset of the home, owners want comprehensive renovation that brings systems and finish to current standard, and every decision must respect the period aesthetic. Iron Crest's East End whole-home work routinely includes complete kitchen renovation with wall removal for gathering space, primary suite addition (most pre-1925 East End homes had only one full bathroom and undersized bedrooms), all original bathrooms renovated with period-appropriate fixtures, full electrical rewire (knob-and-tube replacement is universal), full re-pipe of cast iron drains and galvanized supply lines, HVAC modernization including geothermal coordination where applicable, original wood window restoration or HPC-acceptable replacement, exterior preservation including period-appropriate paint and trim work, sometimes addition (rear or side) for primary suite or family room expansion. Project investment typically $385,000 for moderate-tier work to $1.25M for premium Warm Springs Avenue mansions.
Whole-home strategy in the East End depends heavily on era and architectural significance.
Pre-1900 Warm Springs Avenue mansions
Queen Anne Victorians and Colonial Revivals from approximately 1890–1900. Substantial homes with strong architectural character. Original kitchens were service kitchens; multiple bathrooms; carriage houses or detached structures sometimes converted to ADUs. Modern scope: comprehensive renovation preserving and amplifying period character. Premium budget tier.
1900–1915 Craftsman estates
Larger Craftsman homes on Warm Springs Avenue, Reserve Street, and other principal streets. Original built-ins, beam ceilings, hardwood floors, and architectural details substantial. Modern scope: comprehensive renovation, primary suite addition, full systems modernization while preserving character.
1915–1928 East End bungalows
Dense East End bungalow neighborhoods. Modern scope: comprehensive renovation, kitchen wall removal, primary suite addition (typical), full systems modernization. EPA RRP and HPC standard.
1925–1940 transitional homes
Tudor Revival, Colonial Revival, Spanish Colonial homes. Slightly more modern original layouts. Scope: layout reconfiguration, finish modernization, full systems work.
East End whole-home renovations cluster into recognizable shapes by era and ambition.
1. The Cosmetic Whole-Home Refresh
New flooring, full interior paint, cabinet repainting and fixture replacement throughout, with no structural change and no systems work. This is the entry tier our Boise whole-home page prices, and it is the right scope for an East End house whose systems were modernised by a previous owner and whose finishes are simply tired.
Target homes: East End homes with sound systems and dated finishes. Permit: electrical or plumbing permits only where fixtures move; HPC review only if an exterior element changes.
2. The Craftsman Bungalow Comprehensive
1915–1928 East End bungalow comprehensive renovation. Kitchen wall removal for gathering space. Primary suite addition (typical 380–650 sq ft addition with bedroom, walk-in closet, and primary bath). Original bathrooms renovated with period-appropriate fixtures. Full systems modernization. Original character preservation throughout.
Target homes: 1915–1928 East End bungalows ready for comprehensive renovation. Permit: full plan review with structural drawings; HPC review for additions; EPA RRP throughout.
3. The Period-Respectful Renovation
Comprehensive interior renovation without significant exterior modification. All bathrooms renovated, kitchen renovated with wall removal where appropriate, full systems modernization, finish updates throughout. Architectural details preserved.
Target homes: East End homes wanting comprehensive interior work without major exterior changes. Permit: full plan review; HPC for any exterior modifications.
4. The Warm Springs Avenue Mansion Renovation
Premium scope on Warm Springs Avenue Victorian or Colonial Revival. Comprehensive renovation including kitchen with butler's pantry integration, all bathrooms renovated to spa or near-spa, primary suite expansion, full systems modernization including geothermal integration, original architectural detail restoration. Sometimes includes carriage house ADU conversion.
Target homes: Warm Springs Avenue homes at premium tier. Permit: full plan review; HPC review extensive; geothermal coordination.
5. The Down-to-Studs Period Renovation
Most aggressive scope short of demolition. Strip home to studs and rebuild interior systems and finishes from scratch. New insulation, new mechanical/electrical/plumbing throughout, new layout where it makes sense, premium finishes throughout in period-respectful style. Used when bones are good but everything else is end-of-life.
Target homes: East End homes warranting comprehensive systems and finish renewal. Permit: full plan review with extensive structural; HPC where exterior modifications.
6. The Two-Story Bungalow Conversion
Some East End single-story bungalows can have second floor added (where lot, foundation, and HPC support it). Doubles square footage. Adds primary suite, secondary bedrooms, sometimes office on second floor while preserving original first-floor character.
Target homes: East End bungalows on lots and foundations supporting second-story addition. Permit: full plan review with extensive structural and lateral; HPC review extensive.
The East End / Warm Springs is made up of distinct sub-neighborhoods, each with its own remodeling personality.
Warm Springs Avenue Historic District
The premier residential corridor along Warm Springs Avenue. The City of Boise records it as listed on the National Register of Historic Places in 1979 and designated a local historic district by Boise City in 1996, with a period of significance of 1910–1940 and predominant styles of Queen Anne, Colonial Revival, Mission Revival, Tudor Revival and Bungalow. The City describes the lots on the south side of the avenue as more than an acre, with the north-side parcels more uniform and served by rear alleys. Many homes use geothermal heating drawn from the underlying hot-water aquifer; the City of Boise describes its system as "one of the oldest and largest geothermal systems in the world".
East End — Bungalow Belt
The dense bungalow neighborhoods between Broadway Avenue and the Foothills. The City of Boise designated the East End Historic District a local historic district in 2004, describes it as a thirty-nine-block residential neighbourhood developed through subdivisions beginning in 1890, gives it a period of significance of the 1910s–1940s, and records Craftsman Bungalow as its largest single style at 29 percent, alongside Queen Anne, American Foursquare, Mission Revival and Spanish Eclectic. The City records the district's parcels as small — typically 25 feet wide and 122 feet deep, with corner lots 30 feet wide. Local designation means Historic Preservation Commission review applies to exterior work.
Reserve Street area
The corridor along Reserve Street north of the river. A mix of older homes, post-war ranches and later infill. Much of this area sits outside a designated historic district — confirm your specific address with Boise Planning & Development Services.
East Boise — Table Rock transitional
The transitional zone between the East End and the Foothills, climbing from Warm Springs Avenue up toward Table Rock. Some properties have geothermal heat extending from the Warm Springs district.
Reserve / Eastland infill streets
Smaller streets and infill developments throughout the broader East End. Lots vary widely, and parts of this area sit outside the formal historic district boundaries — confirm your specific address with Boise Planning & Development Services.
Most Boise whole-home remodel projects run $85,000 to $350,000 and up — the band published on our Boise whole-home remodel page. The ranges below run higher than that band because of the East End's pre-1928 housing stock, Historic Preservation Commission review on any change visible from the street, and EPA RRP lead-safe practice on effectively every address. East End whole-home pricing reflects the demanding scope: plaster-and-lath construction, lead-safe protocols, asbestos testing and abatement, knob-and-tube replacement, cast iron and galvanized re-pipe, HPC review, and period-appropriate finish-tier specification.
East End / Warm Springs whole-home remodeling ranges
Cosmetic whole-home refresh (Flooring, paint, cabinet repainting and fixtures throughout — no structural or systems work): $85,000–$195,000 / 3–6 months end to end
Period-respectful renovation (Comprehensive interior work without major exterior modifications): $385,000–$685,000 / 10–16 months end to end
Craftsman bungalow comprehensive (Comprehensive renovation including primary suite addition): $485,000–$785,000 / 12–18 months end to end
Two-story bungalow conversion (Second-story addition on existing bungalow with comprehensive renovation): $525,000–$985,000 / 14–22 months end to end
Down-to-studs period renovation (Most aggressive scope with comprehensive systems and finish renewal): $585,000–$985,000 / 14–20 months end to end
Warm Springs Avenue mansion (Premium renovation on Warm Springs Avenue with extensive scope): $685,000–$1,250,000 / 14–22 months end to end
Pricing assumes Iron Crest's standard scope: full City of Boise permit, EPA RRP lead-safe practices throughout, asbestos testing and abatement as needed, plaster-and-lath demolition and repair where applicable, knob-and-tube replacement, cast iron and galvanized re-pipe, HVAC modernization with geothermal coordination where applicable, period-appropriate cabinetry and finishes, HPC submittal where applicable, and a 3-year workmanship warranty + manufacturer materials warranties.
The City of Boise designates ten historic districts. Two of them cover this area: the Warm Springs Avenue Historic District (National Register 1979, local designation 1996) and the East End Historic District (local designation 2004). Both are locally designated, so Historic Preservation Commission review applies to visible exterior changes in both — a National Register listing alone would not create local design review, but Warm Springs Avenue carries the local designation as well. Confirm the current boundaries and review requirements with Boise Planning & Development Services before an exterior scope is priced.
HPC review is required for any exterior modification visible from the public right-of-way — siding type and colour, window replacement, roof material, porch modifications, additions, accessory structures, fencing. Interior work is exempt from HPC review. Iron Crest handles HPC submittals as part of standard project management. HPC review happens at the Commission's monthly meeting and can add several weeks; confirm current timelines with Boise PDS. Building Division: (208) 608-7070. Planning & Zoning: (208) 608-7100.
Note that the 20 percent federal historic rehabilitation tax credit applies only to income-producing property under National Park Service rules. It does not reach an owner-occupied house, whatever district the house sits in.
EPA Lead Renovation, Repair and Painting (RRP) Program applies to virtually every East End project given the pre-1978 construction. Iron Crest follows EPA RRP lead-safe work practices including HEPA containment, wet-paste paint scraping, lead-safe disposal, and final clearance testing where required.
Many East End and Warm Springs Avenue homes use geothermal heating from the City of Boise Geothermal District — heat exchanged from naturally hot underground water. Geothermal heat affects HVAC scope: existing radiant baseboards, hydronic radiators, or fan-coil units must be properly integrated or replaced with appropriate systems. Iron Crest has experience with the Boise geothermal system specifically.
Asbestos testing is recommended for pre-1980 demolition work — common locations include sheet flooring, mastic, popcorn ceilings, pipe insulation, vinyl asbestos tile, and sometimes roofing felt or building paper. Older East End homes often have plaster-and-lath walls with horsehair binder rather than later drywall — different demolition and repair practices apply.
East End whole-home material strategy emphasizes period-appropriate aesthetic, premium materials at finish-tier matching property values, and durable systems modernization.
Cabinetry — Shaker or inset throughout
Custom cabinetry in painted Shaker or inset (face-frame with doors flush) construction throughout — kitchen, all baths, mudroom, laundry, built-ins. Painted finishes (white, cream, soft sage, deep navy, charcoal) most common. Sometimes stained quarter-sawn oak for primary library or office. Cost: $50,000–$135,000 for whole-home cabinetry.
Hardware — period-appropriate solid metal
Unlacquered brass (Rocky Mountain Hardware), antique bronze, polished nickel, or chrome throughout. Coordinated kitchen, bath, and door hardware. Premium hardware ($25–$120 per piece) appropriate to property tier.
Counters — marble, quartzite, or soapstone
Honed marble (Carrara, Calacatta) or quartzite for kitchens and primary baths. Soapstone for period character. Premium quartz for high-wear secondary spaces. Cost: $90–$220 per square foot installed.
Plumbing fixtures — period-appropriate premium
Kohler Memoirs Stately, House of Rohl Perrin & Rowe Edwardian, Newport Brass Astor, Watermark for premium tier. Toto Drake or Promenade toilets. Cast iron freestanding tubs. Period styling without literal reproduction.
Lighting — period-style throughout
Designer-led layered lighting in period style throughout home. Schoolhouse Electric, Rejuvenation, Visual Comfort, Hudson Valley. Schoolhouse pendants for kitchens, period sconces for baths and circulation, period chandelier for dining, exterior lantern fixtures. Lutron RadioRA control system for whole-home dimming.
Flooring — refinish original or wide-plank match
Original hardwood flooring (oak strip, sometimes fir) refinishable in most cases — preferred over replacement. Where replacement is justified, wide-plank white oak or quarter-sawn oak in plank widths similar to original. Field-finished for color and grain matching.
Tile — period-appropriate patterns
Hex mosaic, subway, basket weave for bathrooms. Penny round for accent. Handmade ceramic for character details. Premium materials (Pratt & Larson, Heath Ceramics, Tabarka).
Heat — geothermal coordination where applicable
Warm Springs Avenue and parts of East End on City of Boise geothermal heat. New systems coordinate with existing infrastructure — new fan-coil units, hydronic in-floor radiant integration, sometimes air-handlers with geothermal coil. Non-geothermal homes get high-efficiency furnace plus heat pump or AC.
Insulation — high-R retrofit in walls and attic
Original East End homes have minimal insulation. Closed-cell spray foam or dense-pack cellulose at walls (R-13 to R-21). Blown cellulose at attic (R-49 target). Mineral wool batts at interior partitions for sound. Cost: $14,000–$38,000 for whole-home insulation upgrade.
Window treatment — restoration or HPC-acceptable replacement
Original wood double-hung windows: restoration ($850–$2,500 per window) preferred where condition allows. Storm windows added for thermal performance ($350–$850 per window). HPC-acceptable replacement (Marvin Ultimate or Pella Architect Reserve simulated divided light, aluminum-clad wood matching original profile): $1,800–$3,800 per window.

How long does an East End whole-home renovation take?
10–16 months for period-respectful renovation; 12–18 months for Craftsman bungalow comprehensive with primary suite addition; 14–20 months for down-to-studs; 14–22 months for Warm Springs mansion or two-story bungalow conversion. Pre-construction (design, engineering, HPC, permitting) is typically 7–10 months; construction is 7–12 months.
What is the typical investment range?
$385,000–$685,000 for period-respectful renovation; $485,000–$785,000 for Craftsman bungalow comprehensive; $525,000–$985,000 for two-story conversion; $585,000–$985,000 for down-to-studs; $685,000–$1,250,000 for Warm Springs mansion. Per-square-foot costs run $250–$500 depending on tier.
Will HPC review be required?
If your home is in the East End Historic District or the Warm Springs Avenue Historic District, HPC review is required for any exterior change visible from public right-of-way (new windows, exterior doors, additions, siding/roof changes). Iron Crest handles HPC submittal as standard part of project management. Plan revisions: $5,500–$22,000. Confirm the current review timeline with Boise PDS.
Can we live in the home during construction?
Generally no for East End whole-home renovations. Scope is too comprehensive — utilities are off, dust and debris extensive, multiple trades work simultaneously, lead-safe practices restrict access. Plan for owner relocation throughout construction phase. Phasing room-by-room is sometimes possible for lighter scopes but extends timeline 4–6 months.
How does geothermal heat factor in?
Warm Springs Avenue homes and parts of East End use City of Boise geothermal heat. Modern HVAC must coordinate with existing geothermal infrastructure — new fan-coil units, hydronic in-floor radiant integration, air-handlers with geothermal coil. Iron Crest has specific experience with the Boise geothermal system. Coordination cost: $5,500–$15,000+ above standard HVAC scope.
What about preserving original built-ins and architectural details?
Iron Crest specifically designs East End whole-home projects to preserve and amplify original character — built-in cabinetry, beam ceilings, hardwood floors, period millwork, original tile in entry vestibules, original stone fireplaces. Preservation costs sometimes more than replacement. We hold no appraisal data and publish no value figure for it — your agent or appraiser can tell you what comparable sales on your street are doing.
What's the process for HPC review?
Initial conceptual review meeting (often pre-application) to understand HPC concerns. Detailed plan submittal with elevations, material samples, sometimes site visits. HPC commission review at scheduled meetings (monthly typically). Plan revisions per feedback. Final approval. Iron Crest integrates HPC requirements at the design stage to target approval on the first or second submission.
What if knob-and-tube wiring is found throughout?
Universal in pre-1940 East End homes. Iron Crest replaces knob-and-tube as standard part of comprehensive whole-home renovation — fire safety, code compliance, modern electrical capacity. House-wide rewire cost: $32,000–$78,000.
