The list price of £4,100,000 is considerably higher than the average house price in the area (£1,262,429). However, the unique riverside location, substantial size (3,413.80 sqft), and additional features like the garden, sauna, and parking justify a higher price. Considering the average price per sqft in the area (£1,096), the asking price may be perceived as high by some, leading to a score of 6.

While the property benefits from a desirable location and outdoor space, the interior design appears somewhat dated and may require some modernisation to meet the expectations of modern buyers. A score of 7 reflects this.

The location on Northumberland Place, Richmond, with its proximity to the River Thames, excellent transport links (Richmond station is 0.72km away), and highly-rated schools, makes this property exceptionally desirable. A score of 10 reflects its prime location.

The property includes a substantial garden with direct access to the river, offering a rare and highly desirable feature in Richmond. The large plot size further supports this high score.
