PROJECT REPORT: SELFBUILD & CUSTOM BUILD PROJECTS
“It’s these little details that tie a building into its historic setting even when the overall design is contemporary in nature”
For Jane this meant that even at the sketch design stage, she was phoning scaffolding companies to check the sizes of scaffolding planks and stanchions to ensure they would fit onto the site. “As an architect this isn’t something you would normally do, but I needed the hard facts so I knew exactly what I had to work with.” Following plans being submitted, permission was granted within six weeks. Jane then began the construction drawings for Building Control and additionally began her project manager role, sourcing materials, preparing quantities and obtaining costings.
Mass appeal To offset the amount of glazing and associated overheating in the building, Jane opted for heavyweight construction with double-skin blockwork walls instead of a timber frame. The glazed gables all face east towards the bay, and as a result, “we don’t have too much glazing facing south,” she says. In the dining area there are rooflights, but no wall apertures facing south; in the living space there’s a large south-facing glass

wall, but a solid roof holding solar PVs. With a heavy thermal mass in the concrete floors and walls, the high peaks and troughs of internal overheating and cooling are eliminated, instead the mass absorbs the excess heat during the day and releases it at night. She explains her ethos: “Timber frame buildings are classified as ‘lively,’ because they are very responsive to heat, and temperatures will spike; I find that very uncomfortable.” Jane continues: “I like the permanency of traditional masonry construction, which is particularly suited to wet climates in Scotland and Northern Ireland.” Jane’s choice was an 80 mm steel frame hidden within the double-skin blockwork walls, and designed on a CNC machine. Jane says: “It’s like a Meccano set; digital perfection. A very slim steel frame sets out the whole building.” Jane was able to erect this frame off the existing concrete slab of the steel shed. This meant no new foundations were required, just a few adjustments in the steel frame to ensure that each leg of the steel was slightly longer to account for the slope on the slab.
