Prepared by architects McKenzie Strickland Associates, the proposals will see alterations made to the East Wing at Taymouth Castle near Kenmore to provide 52 hotel suites and spa facilities.

The revised layouts have been designed to minimising the effect and alteration of the existing fabric of the A-listed building and will replace previous proposals for residential apartment suites, a swimming pool and pamper spa facilities.

According to a supporting statement submitted by the architects, the revisions were necessary to accommodate the applicant’s requirements for a different business plan to accommodate mix of hotel suites to suit current market conditions and help attract new investment that is essential to continue the ongoing restoration.

The building, which was used as a honeymoon base for Queen Victoria and Prince Albert, has already undergone extensive £23 million refurbishment under its previous owners.

The statement added: “The proposals, which will replace the consented 14 hotel suites with a total of 23 smaller bedroom suites is critical in terms of the new investor’s business plan to ensure the castle renovation and operation is financially viable.

“It will help deliver the phased restoration and revitalisation of the castle and the ultimate vision for Taymouth Castle estate as a whole.”

The statement continues: “The net impact of the proposals at this level is to increase the number of people who can enjoy the historic castle as guests whilst retaining the quality of the accommodation and doing much to reveal the significance of the principal spaces with the minimum loss of historic fabric.”

The majority of the scenic castle has been modernised but the latest plan will see new floorplan layouts in the second and third floors of the main tower along with re-configuration of the west wing to build the 23 smaller bedrooms.
