[Assessed 101.2%] Detached house in Funabashi, Chiba — 13 min from Takanekido Sta.

A newly built detached house in Shibayama 6-chome, Funabashi, Chiba, a 13-minute walk from Takanekido Station on the Keisei Matsudo Line. Two more stations are within walking distance (Kita-Narashino on the Toyo Rapid Railway, 19 minutes; Takane-Kodan on the Keisei Matsudo Line, 18 minutes). The site faces a 4 m road on the east side in a flat residential block, and Takasato Elementary School is 830 m (about 11 minutes) away.

Two-storey wood-frame construction with a floor area of 100.81 sqm (3LDK plus two storage rooms) on a 117.24 sqm lot. Completion is scheduled for December 2026 and the current status is "under construction". Site photographs taken in September 2026 show the frame and exterior work in progress, so the finished appearance can only be checked against the developer's rendering. The listing describes it as a ZEH-standard energy-saving house with insulation rated 5 on a 7-step scale and a 20% reduction in energy consumption. Utilities are municipal water, public sewerage and city gas, with an outdoor car space.

The lot includes a 13 sqm private-road burden (4 m wide, east side). Treating it as included in the listed 117.24 sqm, we deducted it and calculated the land value on an effective 104.24 sqm. Without the deduction the assessed ratio is 105.84%; with it, 101.17% — either way above our 80% threshold. The inheritance-tax road price is 125,000 yen/sqm for 2026 (map 06108, leasehold ratio D). Because the building is not yet completed, the full 22-year statutory life remains, giving 220,000 yen/sqm x 100.81 sqm = 22,178,200 yen for the building and 13,030,000 yen for the land, 35,208,200 yen in total.

Two points need confirmation. First, the SUUMO listing notes "city planning road" under other restrictions. Neither listing states the affected area or ratio, the route name, or whether the project has been authorised. Land inside a planned-road zone is restricted under Article 53 of the City Planning Act — in principle two storeys or fewer, no basement, and a structure that can be removed or relocated easily — and may be expropriated once the project is authorised. We did not deduct any area for it, but it can explain a price below the road-price total. Second, the road classification differs between sources: the floor plan marks "designated-position road, 4 m" while Kenbiya's frontage field reads "no positional designation". Since building confirmation (No. 26UDI1C-Ken-01567) has been granted, legal frontage appears secured, but the road type should be confirmed with the agent.
