The building was restored under a National Estate Programme Grant by architects Fisher Lucas and leased to Hawkesbury Shire Council. A Permanent Conservation Order was made over the property in 1978 by the Minister for Planning and Environment under advice from the Heritage Council of NSW and the order was gazetted on 14 December 1979. This covered the land, the house, the brick outbuilding and boundary fence and it was only the 3rd made in New South Wales under the Heritage Act 1977. It has been used for a variety of uses since its acquisition by the state government, including various now-closed restaurants ("Lachlan's Restaurant", "Governor's Choice" and "The Linden"), as a boarding house, and for many years as a bookshop. It was sold in November 2006, and was vacant and advertised for lease in August 2017. Loder House is an 1834 two storey brick Georgian townhouse with attic and later Victorian two storey timber verandah with cast iron lacework balustrades and verandah brackets. The upper floor has five symmetrically placed French Doors with stone voussiors, opening onto the verandah, whilst the ground floor has paired windows with stone voussoirs and sills, flanking a central entrance with an arched fanlight. The main facade is of face sandstock whilst the side walls have been rendered. The 1975 National Trust (NSW) listing said that at that time the street facade was stuccoed, the remainder of the external walls face brick. The corrugated iron roof has been replaced when the building was restored. The verandah is stone flagged. The grounds contain an 1830s boundary wall and an unusual square outbuilding which dates from the time of construction of Loder House. Some stone flagging survives in the rear yard. The townhouse today has frontage to the WIndsor pedestrian mall. The building appears to be in excellent condition and was restored in 1975. The site has some archaeological potential, particularly in the grounds surrounding the outbuilding, whose original purpose is unclear. The house is substantially intact, despite it nearly being burnt down. Loder House is a rare intact two storey brick Georgian townhouse, located in the main street of Windsor.

The grounds of the house contain an 1830s boundary wall and an unusual square outbuilding which dates from the construction of the house.
