Bute House repairs 2017 to 2018: cost breakdown

Published: 14 Apr 2018

Detail of repair work carried out at the official residence of the First Minister of Scotland.

Bute House, the official residence of the First Minister of Scotland, was closed between October 2017 and March 2018 for essential repair work. Details and costs of this work are outlined below.

Bute House background

Bute House is central to the category A listed buildings to the north side of Charlotte Square, Edinburgh. Charlotte Square features in James Craig's 1776 masterplan for the New Town of Edinburgh with designs for the facades by Robert Adam. The square was constructed between 1793 and 1805 and is now part of a World Heritage Site.

Following devolution in 1999, Bute House was designated as the official residence for the First Minister. The building, which was previously used as the official residence for the Secretary of State for Scotland, is also used for Cabinet meetings, official engagements, receptions and meetings

Bute House is owned by the National Trust for Scotland and the cost of the annual lease paid to National Trust for Scotland is £70,000 per year plus VAT. Under the terms of the lease, Scottish Government is liable for all costs of repairs and maintenance.

The conservation and care of Bute House is delivered through partnership and collaboration between the Scottish Government, Historic Environment Scotland (HES), National Galleries of Scotland, National Trust for Scotland (NTS) and the Bute House Trustees. These stakeholders are the current custodians of Bute House and all stand ready to deal with unscheduled repairs, which are not uncommon for buildings of this age.

Overview of repair and maintenance

Changes to the Bute House Drawing Room ceiling were identified as part of routine monitoring during the first half of October 2017, and HES and the Scottish Government agreed the need for immediate repair work to the Drawing Room ceiling and the floor directly above. The ceiling and floor were investigated, and repairs took place between October 2017 and March 2018.

Necessary repair work was coordinated by Historic Environment Scotland and Scottish Government, and included input from the National Trust for Scotland, the National Galleries of Scotland and the Bute House Trustees.

In addition, the closure of Bute House for ceiling repairs provided Scottish Government with the opportunity to carry out building maintenance. Under the terms of the Bute House lease, the Scottish Government is required to mitigate the impact of building dilapidation. The unscheduled house closure provided a window of time to gain efficiency and cost savings by carrying out essential repairs at the same time as the ceiling repairs.

Drawing room ceiling and floor repairs

The ceiling and floor repair work was carried out under the direction of HES conservation teams, supported by specialist contractors. This specialist conservation has been summarised by HES below. Ceiling and floor repairs.

The works to the drawing room and the second floor directly above were undertaken to consolidate and retain the historic fabric and interior. Fine line cracks across the ceiling to the drawing room were most noticeable by the external wall, in the centre of the room and at the internal wall to the stairwell. Some cracks changed direction in a more rectilinear pattern, unusual for lathe and plaster, suggesting there could be additional loading or fixings above.

The deflection towards the centre of the ornately decorated ceiling was also more evident in close assessment with specialist plasterwork contractors and the plaster was carefully reinforced with screw fixings prior to raking out cracks and filling for redecoration.

There did not appear to be an immediate risk of large scale detachment and investigation continued to assess the upper surface of the ceiling by lifting the floor boarding in the rooms directly above. This confirmed that the ceiling lathe was directly fixed to the timber floor joists. Earlier repair works (dating from the 1980s) were apparent above the rectilinear cracks seen below.

HES structural engineers assessed that the deflection at the mid span of the floor above the drawing room could be considered as inevitable; the dimensions of the timber joists are less than expected for modern standards and the permanent deflection varied by up to 60mm.

The joists are partly built into the external masonry wall and into the internal masonry wall, which also supports the cantilevered stone stairway. It was most important to control any further loading to the floor structure and to plan access and works to minimise the effects of impact and vibration.

The floor loading capacity would also be reduced at the notches for service pipes and cables, including where drilled through the centre of joist and at the centre of the ceiling below, where the joist had been cut at midpoint and strapped either side.

Approximately seven tonnes of ash deadening was carefully removed from directly above the lathe and plaster ceiling, and protection measures were built in for the health and safety of those carrying out investigations and the works to follow. This reduced the risk of fall through the lathe and plaster and also restrained twist movement of the timbers.

HES stonemasons worked at the external wall and at the internal wall to the stairwell to form pockets to suit new steel beams. There are now 20 new steel beams built in to strengthen and support the existing timber joists.

Each beam is formed in three sections of steel channel bolted together to follow the varied deflection of the retained timber joist to which it is fixed. Timber dwangs as fitted now stiffen and strengthen the floor joist structure.

The new sound deadening with limestone chips and mineral wool is significantly lighter, at approximately three tonnes, and is now supported by the floor structure. The design and installation allowed the chandelier position to be reinforced and for redundant services to be removed, with pipes and cables now set out between new packing to the floorboards.

Laser survey set out control points for new skirting boards with the original top beading profile and, using traditional joinery skills and craftsmanship, the new floorboards meet comfortably at the three doorways. Vibration across the floor has also been assessed as reasonable to current standards and the construction can be considered suitable for the residential occupation and use of Bute House.

Some settlement and vibration to the building fabric is to be expected for a building of this age in the centre of the city.

The drawing room has been redecorated using traditional skill and care to retain the delicate plaster decoration work seen at the ceiling, cornice and frieze. Paint analysis revealed earlier decoration layers including small areas of gilding at the ceiling cornice. The parquet flooring in the drawing room has been repaired where there was surface damage at doorways and windows prior to dust controlled sanding and finishing with a clear varnish.

Associated works and improvements

Under the terms of the Bute House lease, the Scottish Government is required to mitigate the impact of building dilapidation: therefore the unexpected and unscheduled house closure provided a short window of time to gain efficiency and cost savings by carrying out essential repairs at the same time as the ceiling repairs.

The Scottish Government used the house closure to investigate non-functioning ventilation systems and to carry out a drain survey, as well as preparatory works to introduce zoned heating control to the building and take heating to the third floor, and basement offices.

The essential heating improvement will also enable Scottish Government to control the wider air quality environment in the house (monitored air quality will improve living and working conditions in the house). In turn, this will also provide a more stable environment for collections management (furniture, objects and artworks), and will improve the general condition of the building fabric, and manage damp.

These essential maintenance works and heating improvements were commissioned and priced through Scottish Government Facilities Services, who interrogated costs to ensure value for money. An overall description of the works and associated costs for the three projects (heating, ventilation and drainage, and cloakrooms and bathroom projects) is as follows:

Project Total cost
Heating works: essential works to take heating to the third floor and to basement offices; and replace the non-functioning heating control system with a system that will enable in-building control. £202,119
Ventilation and Drainage works: investigation and repair of drainage and ventilation systems across four floors (basement offices to third floor and attic level). £48,398
Cloakrooms and bathrooms: an all-building project. Following on from drainage and ventilation works, SG reviewed all toilets and bathrooms and identified an all-building programme for four cloakrooms/toilets and three bathrooms in both public and private areas. £96,834
