Who we are
Home Extensions Built for Leyton Homes
A house extension is one of the few building projects that changes both how a home works day-to-day and what it's worth. Getting it right means more than laying bricks — it means understanding party wall obligations, whether the work is permitted development or needs full planning consent, and how the structural steelwork ties into the existing house before a single trench is dug.
Dakus Construction manages the whole build in-house — groundworks, structural steel, brickwork, roofing, first and second fix, plastering and decorating — so you deal with one team from the first site visit to the final sign-off. No handing you between an architect, a separate builder and a structural engineer with no one accountable for the whole job.
We regularly build extensions across Leyton, Leytonstone and the wider Waltham Forest area. If your street isn't listed below, call us and ask — we travel across East London and beyond for the right project.

What we do
Our Home Extension Services in Leyton
Every Leyton terrace, semi and end-of-terrace calls for a different type of extension. Every service below is delivered by our own team, start to finish.
Single-Storey Rear Extensions
The classic way to open up a kitchen or living space at the back of the house — usually falls under permitted development.
Double-Storey Extensions
Add a bedroom or bathroom above and living space below — the most cost-effective way to add real floor area to a family home.
Side Return Extensions
Build into the alleyway beside a Victorian or Edwardian terrace to square off an awkward kitchen and flood it with light.
Wrap-Around Extensions
Combine a rear and side return extension into one open-plan space — the biggest single upgrade most East London terraces can make.
Kitchen-Diner Extensions
Open-plan kitchen, dining and living space with bi-fold doors onto the garden — designed and fitted as one connected project.
Structural Steelwork & Building Regs
Engineer-calculated steel beams, load-bearing wall removal and full building control inspection and sign-off on every project.
Local knowledge
We Extend Every Type of Leyton Home
Leyton's housing stock ranges from tight Victorian terraces to post-war semis and converted flats, and each one dictates a different approach to foundations, party walls and steel spans.
01
Victorian & Edwardian Terraces
Leyton and Leytonstone's core terraced streets. Narrow plots with a side return almost always worth reclaiming — shared party walls mean an agreement is nearly always required.
02
1930s Bay-Fronted Semis
Pockets around Whipps Cross and Cann Hall. Generous rear gardens and side access make these some of the easiest Leyton homes to extend into.
03
Ex-Council & Estate Housing
Estates around Lea Bridge and Francis Road. Solid, consistent layouts, well suited to rear and side extensions once freehold consent is confirmed.
04
Period Terraces in Conservation Areas
Parts of Leyton near conservation areas bordering Walthamstow. Full planning permission and design guidance compliance is usually required rather than permitted development.
05
Larger Detached & Corner-Plot Homes
Larger plots towards Leytonstone and Wanstead borders. Room for double-storey and wrap-around extensions with larger structural steel spans.
06
Buy-to-Let & Pre-Sale Refurbs
Landlords and vendors working to a deadline. We scope the extension work that actually moves valuation and rental yield, and hit fixed dates.
Budgeting
What Does a Home Extension Cost in Leyton?
Nobody can quote an extension they haven't seen, and any builder who gives you a firm figure over the phone is guessing. What we can do is be straight about what drives the number.
Four things move an extension budget more than anything else: the footprint and number of storeys, the amount of structural steelwork needed, the fit-out specification you choose for the finished space, and whether groundworks turn up anything unexpected once we open up.
How we quote
We visit, measure, and talk through what you want the extension to achieve. You then get a written, itemised, fixed-price quote — labour and materials broken out line by line, so you can see exactly what you're paying for and adjust the specification if the number needs to come down. The price we agree is the price you pay unless you ask us to change the scope.

Questions
House Extension FAQs
How much does a home extension cost in Leyton?
Costs vary depending on footprint, number of storeys, structural steelwork and finish specification. We provide a fixed, itemised quote after a free home visit so there are no surprises.
How long does a house extension take?
A single-storey rear extension typically takes 10–14 weeks from groundworks to handover. Double-storey and wrap-around extensions take longer, and we give you a realistic programme in your written quote.
Do I need planning permission, or does permitted development cover it?
Many single-storey rear extensions fall under permitted development rules, subject to size limits and your property not being in a conservation area. Larger extensions, side returns beyond permitted limits, and homes in conservation areas usually need full planning permission. We assess this during your consultation and handle the application if needed.
Will I need a party wall agreement?
If your extension involves work on or near a shared wall with a neighbouring property — common with East London terraces — you'll likely need a party wall agreement under the Party Wall Act. We guide you through notifying neighbours and, where required, help coordinate a party wall surveyor.
Are you insured and qualified?
Yes — we work with qualified structural engineers on every extension, hold full public liability insurance, and all completed work is covered by insurance-backed guarantees.
