About this home
Affectionately known as "The Castle," this extraordinary Snell Isle estate is a masterpiece of timeless architecture, exceptional craftsmanship, and effortless indoor-outdoor living. Designed by renowned architect Daniel Dawson, this remarkable 4-bedroom, 4-full-bath, and 1-half-bath residence encompasses 5,640 square feet of meticulously crafted living space. Constructed of cinder block on both the first and second floors, the home reflects enduring strength and superior craftsmanship.

Rich custom walnut flooring extends throughout both levels, while the formal living and dining rooms showcase an exquisite chevron pattern.

Designed for entertaining and everyday living, expansive gathering spaces flow seamlessly to the outdoor living areas through multiple walkouts to the patio.
A magnificent main staircase, gracefully rising within the home's iconic front turret, serves as an architectural centerpiece, while a spiral staircase tucked within the mudroom provides convenient secondary access to the second floor. The chef's kitchen features an oversized center island, custom Allikriste cabinetry, a professional-grade Wolf range, built-in beverage drawers, and abundant prep space. Outside, the resort-inspired entertaining areas include a fully equipped outdoor grilling area, multiple covered seating spaces, and an inviting outdoor living room with a gas fireplace.
Distinctive indoor and outdoor wood-burning fireplaces can be enjoyed independently or simultaneously, creating a seamless connection between the home's interior and exterior living spaces.

The primary suite offers a spa-inspired bath with a steam shower, and a whole-home Generac generator provides added peace of mind.

Data is deemed reliable but is not guaranteed by the MLS to be accurate.The Messtimate
This is a deliberately dumb estimate — living area times a range of recent neighborhood $/sq ft, and nothing else. It is not an appraisal, not market value, and not a valuation of this home. Even a tight range from comparable sales can’t price a specific home — here’s why.
Actual list price: $3,925,000 — compare it against the range above. The Messtimate is a blind sqft estimate; the list price reflects this specific home.
A 28% spread on the same house — and that gap is exactly what an automated guess can't see:
- Condition & updates — a renovated kitchen or new roof vs. dated finishes can swing value six figures; sq ft can't see it.
- The lot & views — a premium golf, water, or preserve lot vs. a road-facing one: same sq ft, very different price.
- Outliers skew it — one flip or distressed sale in the comps drags the whole $/sq ft up or down.
- Carrying costs & concessions — this home carries HOA dues of $4/mo; with insurance and any seller-paid buydown, that changes what a buyer actually pays, and a sq ft estimate ignores all of it.
- The pool — a private pool carries cost and value that living area doesn't capture.
And here's what the live market is doing — which the number above ignores entirely:
- This home: 44 days on market vs. a 145-day community median
- 1 active listing competing
- ≈3.0 months of supply
- 4 closed here in the last 12 months
For reference, this home is listed at $3,925,000 ($696/sq ft) — a number set with analysis a Messtimate can't do.

Buyer research checklist
Items worth confirming for 401 Snell Isle Boulevard, chosen from what the record shows. This is general guidance, not advice about this specific property.
- Built in 2010 (16 years): ask for the roof and HVAC replacement dates — insurers commonly ask for roof age on homes this old, and it changes the premium.
- HOA dues are listed at $4/mo: request the current budget, reserves, and rules before relying on that figure or on any restriction.
- FEMA flood zone AE: lenders generally require flood insurance here — get an elevation certificate and a flood quote before the inspection period ends.
- Get a homeowners insurance quote for this specific address in Pinellas County; a wind-mitigation inspection and, on older homes, a four-point inspection can change the premium.
- Private pool: confirm the barrier or alarm meets the state residential pool safety code and ask for pump, heater, and resurfacing records.
- Listed living area is 5,640 sq ft: verify it against the property appraiser's record and measure before relying on it.
- Order a survey to confirm lot boundaries and easements.
- Review permit history with the county.
- Property taxes: the estimate on this page (about $41,212/yr) assumes reassessment at the list price; the seller's homestead cap does not transfer, so their current bill is not a guide.
- Confirm school zoning directly with the district.
