What Our Clients Say
Real reviews from our satisfied customers.
“The quality of the work, their high standards, and their professionalism, along with effective and proactive communication made a refreshing change from the builders I have used in the past. Even when we changed our minds and ideas during the job Cormac’s patience and support emphasised that he wanted to make sure that the finished product was exactly what we wanted…”
Michael Marks
“A great transformation of my bathroom into something modern and sleek. Cormac was professional to work with from the start and was very helpful in taking my ideas and sourcing products to fit the space and look aesthetically pleasing. I felt confident in working with the company as I could ask questions and I was also pleased to get suggestions and ideas…”
Vera Jajechnyk
“I received an excellent service from the outset with a very high standard of the completed work. Cormac was very responsive to my wish for a traditional period bathroom and helped me to source the suite, the tiles, the paneling and flooring. The team are respectful to the home generally. I am very pleased with the finished bathroom…”
Philomena Mulcahy
“From scoping to completion, Cormac was always very responsive, answering any questions we had on product selection and helped us source the products to get the best price. His team worked extremely hard and a big shoutout to Greg for his attention to detail! We couldn’t be happier with the results and would highly recommend Buildaway for any building project in the future…”
Georgina Ehmcke
“The team turned up when they said they would and kept the house tidy each day, which made a big difference while we were living in the property during the works. The quality of the finish is excellent. The bathroom looks fantastic and the bedrooms feel completely refreshed. We wouldn’t hesitate to recommend Cormac and the Buildaway team…”

Frequently Asked Questions
Your questions about home extensions in Stratford, answered.
How much does a home extension cost in Stratford?
As a guide, a home extension in Stratford (E15 and E20) runs roughly £40,000–£60,000 for a single-storey rear, £60,000–£80,000 for a larger or wrap-around scheme, and £100,000+ for double-storey work. UK build costs sit around £1,800–£3,000 per m², and London consistently lands at the upper end. Buildaway fixes your figure in a written quote after survey.
How long does a home extension take in Stratford?
A single-storey extension in Stratford typically takes 12 to 14 weeks on site, with double-storey nearer 16–20. Add lead-in for planning - Newham Council runs an 8-week determination period - plus party-wall notices, which need up to 2 months in E15 and E20 terraces. Buildaway starts the paperwork early so the build is not waiting on it.
Do I need planning permission for an extension in Stratford?
It depends on your E15 and E20 property. Permitted development covers a good number of Stratford rear extensions, but if you are listed, in a conservation area, or leasehold, the answer changes and Newham Council consent is needed. Buildaway confirms what is achievable at feasibility rather than designing something that gets refused.
What types of extension do you offer in Stratford?
All the usual types: single-storey rear, side-return, wrap-around, double-storey and basement work. In Stratford the choice is set by the plot and the planning position, not preference. Buildaway measures the E15 and E20 site and boundary first, then advises honestly on what is achievable.
Do Buildaway handle both design and construction for Stratford extensions?
Both, on one contract. For Stratford clients Buildaway handles drawings, structural engineering, consents and construction. Splitting design from build is where E15 and E20 extension projects most often lose money, because the gap between them is nobody's problem until it is yours.
Are your extension specialists local to Stratford?
Yes. Buildaway works across Stratford and the surrounding E15 and E20 streets regularly, so we know the plots around Maryland and East Village, the drainage runs, and what Newham Council has approved nearby. Local precedent is genuinely useful - knowing what got consented on the next street shapes a scheme that will pass.
