Retrofit & net-zero in Dalston
Dalston is London Borough of Hackney's victorian terraces (1860-1895) + edwardian + post-war council infill + 2010s new-build around dalston junction station submarket. Many Dalston Victorian terraces have original rear-return kitchens built in London stock brick on shallow 900mm-depth footings — a 3m deep rear-extension here almost always requires underpinning of both the return and the neighbour's return, a factor that adds roughly £18,000-£30,000 on a standard rear extension.
What a retrofit & net-zero project looks like here
Many Dalston Victorian terraces have original rear-return kitchens built in London stock brick on shallow 900mm-depth footings — a 3m deep rear-extension here almost always requires underpinning of both the return and the neighbour's return, a factor that adds roughly £18,000-£30,000 on a standard rear extension.
Hackney's Core Strategy energy-and-carbon overlay means a rear extension over 50 m² triggers a whole-building Part L calculation rather than the default extension-only calculation, often pushing the existing boiler spec up to a heat pump or hybrid to pass — a secondary scope surprise that adds £4,000-£9,000.
Because Dalston's post-1960 council infill is often solid-wall unfilled-cavity construction, EWI (external wall insulation) retrofit has been a common Section 106 condition for new-build planning gains in the area — meaning contractors need familiarity with adjoining-EWI surveys.
PAS 2035 whole-house retrofit, ECO4 grant scoping, MCS heat-pump install, GLA London Plan 2021 carbon targets and Mayor's Energy Efficiency Fund. In Dalston specifically, victorian terraces (1860-1895) + edwardian + post-war council infill + 2010s new-build around dalston junction station stock means retrofit & net-zero scope is shaped by the neighborhood's dominant construction typology. Baily's London scoping flow factors dalston ca on select streets + kingsland high street frontage and hackney core strategy energy + carbon overlay into the estimate before a contractor is involved.

Who is Baily?
Baily is named after Francis Baily — an English stockbroker who retired at 51, became an astronomer, and in 1836 described something on the edge of a solar eclipse that nobody had properly articulated before: a string of bright beads of sunlight breaking through the valleys along the moon’s rim.
He wasn’t the first to see them. Edmond Halley saw them in 1715 and barely noticed. Baily’s contribution was clarity — describing exactly what was happening, in plain language, so vividly that the whole field of astronomy paid attention. The phenomenon is still called Baily’s beads.
That’s what we wanted our AI to do. Every inbound call and text has signal in it — a homeowner’s real question, a timeline, a budget, a hesitation that means “yes but.” Baily listens to every one, 24/7, and finds the beads of light.
Baily was a businessman before he was a scientist. That’s our vibe too.
Questions LA homeowners actually ask
Dalston retrofit & net-zero projects typically run $18K–$285K. Dalston's victorian terraces (1860-1895) + edwardian + post-war council infill + 2010s new-build around dalston junction station stock, combined with dalston ca on select streets + kingsland high street frontage, puts most mid-complexity projects in the $152K range. Baily scopes the exact band once you describe the work.
