elegance found in most period Dublin homes which generally have interconnecting front and back rooms. “We decided to dispense with the traditional hall and staircase arrangement which normally dominates houses. Hallways often don’t have much character; they’re not generous spaces but seem to rob the house of other useful space. Here we’ve woven the vertical spaces into the house in a way that we feel makes it more interesting and experiential.”


The spatial and functional concept of the design is traditional with bedrooms upstairs, living rooms downstairs and a mezzanine in between. “The bedrooms are quite modest. If you’re only building 135m2


it makes sense not to


put your space into bedrooms and to put more space into the communal areas. We have used part of the roof space to create more volume, though from the outside it looks like a two storey house with a pitched roof. “On plan there is a wide strip for the living spaces and a narrow strip for the kitchen, bathrooms and service spaces. I designed the kitchen and bathrooms to be close together to allow for very short pipe runs and to make the plumbing function well. I don’t like voids in construction, partly because it’s a waste of space, but also because if there’s a void anywhere near the outside of the house it can lead to potential heat loss or condensation issues,” says John-Barry. “The plumber and electrician weren’t particularly happy about this as it means less space for cables and pipes. To have a two strip design like this requires a minimum width of 5.7m internally. Using CLT for the superstructure helped with this because CLT walls are up to 50% thinner than those of standard masonry construction.”

When it came to the build, they were fortunate not to face any major site constraints. “The Lane at 6m across was wide enough for the CLT delivery truck to drive down. There was also enough space at the front of the house for the mobile crane, however with the house occupying 50% of the site and the removal of the old garage – except for two walls which we retained for the garden enclosure – we were left with nowhere to store materials,” explains John-Barry. “We were very lucky that our neighbours were happy for us to use their garage for storage during the construction phase. This was a blessing especially as we were building on a tight site at the same time as procuring materials. “Unfortunately, we had a lot of supply chain issues including fl uctuating prices, quantities and supply line closures. Not only were we dealing with Covid, but it was post-Brexit and there was still a lack of clarity about the delivery routes on the island of Ireland as well as a shortage of materials – particularly rockwool insulation. These delays of materials and some huge price increases made it a very diffi cult aspect of the project.,” John-Barry continues. “Once we were up and running with the build though, our mass timber specialist G-frame Structures’ team of just three operatives were onsite for a total of only eight days to install the entire superstructure, which is kind of extraordinary. It had taken eight months of planning followed by just eight days to see the form of the house realised. The speed plus ease of the CLT installation was defi nitely the high point of the project.” he adds. Teach Spruis has achieved Passive House standard of 0.55 ACH airtightness.
