Architecture for London, 2020
1 Halliwick Road, N10 1AA
A low energy refurbishment of an Edwardian house, with rear extension and loft conversion. Wood fibre insulation, MVHR, airtightness layer, triple glazing, timber structure and low embodied energy materials.
Its at least half an hour walk from any tube / rail station, so best to take the 134 or 43 bus from Highgate tube (takes 9 minutes from Highgate on the bus)
This project aims to be an exemplar for the sustainable retrofit of a typical terraced home in London, within a constrained budget.
Both embodied energy and energy in use have been considered in depth, and there are a number of successes in addition to lessons learned for next time!
Design features include:
- Minimising concrete structure
- A continuous airtightness layer, formed by either intello plus membrane (where timber construction e.g. floor, loft and rear extension) or 10mm lime plaster where existing masonry walls
- Insulation to existing floors and masonry walls, externally at the side and rear, and internal wood fibre at the front
- Triple glazing for all new contemporary windows and rooflights
- Only timber structure has been used in the loft conversion, no steels.
- Retaining some masonry nib walls downstairs to avoid steel box frames where possible
- Using lime plaster, mortar and render rather than cement based products
- Highly insulated 172mm SIPS for the rear extension
- Natural stone rather than concrete floor finishes
- Avoiding concrete / cement in garden landscaping
