Loft conversions, extensions and refurbishments across East London — from Victorian terraces in Hackney and Bethnal Green to larger family homes on the Essex border in Loughton and Chigwell. Director-led, fixed-price and fully guaranteed.
East London spans dense Victorian terraces and warehouse conversions in Hackney, Bethnal Green and Bow, the Edwardian streets of Walthamstow and Leyton, post-war stock around Stratford and Dagenham, and larger detached and semi-detached homes out on the Essex border in Loughton and Chigwell. Each calls for a different approach to adding space.
L-shape dormer loft conversions and rear extensions are the staple across the Victorian terraces of Hackney, Bethnal Green and Walthamstow. Toward the Essex border in Loughton and Chigwell we take on larger double-storey extensions, full refurbishments and basement work on detached homes. Across Dagenham and Stratford the typical brief is a rear extension or loft conversion to gain a bedroom and a bigger kitchen.
East London has been one of the fastest-changing parts of the capital, with young families buying period terraces in Walthamstow and Hackney and professionals upgrading homes out toward Loughton. The brief we hear most is straightforward: more space and a better kitchen without leaving a neighbourhood they've come to love.
East London spans more property types than almost anywhere in the capital. Inner boroughs — Hackney, Bethnal Green, Bow — are dense Victorian terraces interspersed with warehouse and ex-industrial conversions. Walthamstow and Leyton add Edwardian terraced streets. Out through Stratford and Dagenham you find post-war and regeneration stock, and on the Essex border in Loughton and Chigwell, larger detached and semi-detached homes on real plots. Each calls for a different route to more space — and a different planning conversation.
As across the rest of London, the subsoil is mostly London Clay: a shrink-swell ground that moves with the seasons and with nearby trees. It's the reason extension foundations here often need to go deeper than expected. We assess the actual ground and tree proximity before quoting rather than pricing a standard trench and hoping.
East London is where the 'it's only a loft, it's permitted development' assumption catches people out most. Large parts of Hackney are covered by conservation areas and Article 4 directions, which remove permitted-development rights — so a loft or extension that would be automatic in an outer borough can need a full planning application here.
Tower Hamlets (Bethnal Green and around) combines dense conservation areas with a very high proportion of flats and maisonettes — and permitted development simply doesn't apply to flats, so almost any external change needs both planning permission and freeholder consent. Walthamstow Village and other conservation areas add their own restrictions. The practical upshot: in East London you check the address first and design second. We do exactly that.
Push out to Loughton and Chigwell and the brief changes — bigger homes, bigger plots, and the green setting of Epping Forest. It's prime territory for double-storey extensions, full refurbishments and basement work. But it comes with Green Belt and Epping Forest planning sensitivities and local conservation areas, so larger projects more often need a full planning application than an inner-London loft would. The answer is to design early and engage the council before committing to a scheme.
Large parts fall within conservation areas with Article 4 directions that remove permitted-development rights — many lofts and extensions need a full application here. Always check the address first.
Dense conservation areas and a high share of flats and maisonettes, which have no permitted-development rights — a planning application (and freeholder consent) is usually required.
Walthamstow Village and other conservation areas restrict external changes; terraces outside them are generally permitted-development-friendly for rear dormers and extensions.
Fewer conservation constraints and more post-war stock — often the most straightforward boroughs for permitted-development extensions and lofts.
Larger plots and a greener setting, but Green Belt and Epping Forest sensitivities plus local conservation areas mean bigger projects often need planning — design early.

Not always. Large parts of Hackney are covered by conservation areas and Article 4 directions that remove permitted-development rights, so work that would be permitted development in another borough can need a full planning application here. We confirm your address's exact status with Hackney before assuming anything.
No — permitted development applies to houses, not flats or maisonettes, which are common across Tower Hamlets and inner East London. Almost any external alteration to a flat needs planning permission, and usually freeholder consent too. We handle both as part of the project.
Yes — we cover the whole of East London and the Essex border, including Bethnal Green, Hackney, Walthamstow, Stratford, Dagenham, Loughton and Chigwell. The first survey and fixed-price quote are free.
Yes — it's one of our most common projects across the Victorian terraces of Hackney, Bethnal Green and Walthamstow. An L-shape dormer typically adds a double bedroom and en-suite, gaining around 25–35sqm of usable space.
Many loft conversions and rear extensions in East London fall under permitted development, so no full planning application is required. We always check and, where it applies, secure a Lawful Development Certificate to protect your investment.
Yes — £2M public liability insurance and a 1-year workmanship guarantee on every project, with building regulations sign-off included as standard.
