What Our Clients Say
Real reviews from our satisfied customers.
“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
“I was recommended Buildaway by a colleague as I was impressed by the work they had done for my colleague. From the moment I contacted Cormac, I knew I was in good hands. He was incredibly friendly and accommodating right from the start. The very next day, he was at my property, taking measurements and discussing design options. What really impressed me was Cormac's honesty…”
Nana A.
“It was an absolute pleasure working with Cormac and the Buildaway team. Greg is an absolute star. Cormac’s communication and advice was excellent, and the organisation and sourcing of additional materials was brilliant. A truly great team, I would thoroughly recommend Buildaway if you are after a stress free and top quality renovation.”
Sim Lewis
“They were also very professional day to day - always tidy, and cleaned up really thoroughly when taking away all rubbish at the end. They stuck to the agreed timelines, and pricing was transparent throughout, with clear communication on any issues as they arose. Overall, I’m really pleased with the result and felt I could trust them throughout. I wouldn’t hesitate to recommend them…”
Sean Kelleher
“From my first contact with Cormac, I was in good hands. His team turned my vision into reality, communicating with me every step of the way and offered helpful suggestions which turned my bathroom into an oasis. I could not be happier and would highly recommend their services. Thank you to the team of Buildaway Construction Ltd…”
Jackie Brown
“Greg's attention to detail and dedication elevated both the experience and the result - he certainly knows his way around a tile. In addition to the bathroom refit, Cormac replaced all the plastic switches, sockets and pull-cords in the house with brushed brass. Highly recommended and will certainly work with the Buildaway team again…”

Frequently Asked Questions
Your questions about loft conversions in Forest Hill, answered.
How much does a loft conversion cost in Forest Hill?
Buildaway prices Forest Hill lofts from survey. As a working guide across SE23: £25,000–£34,000+ for Velux, £34,000–£52,000+ for dormer, £48,000–£62,000++ for mansard or hip-to-gable. What moves it is headroom, the steel design and whether the stair can land without losing a room below. The written quote is fixed before work starts.
How long does a loft conversion take in Forest Hill?
Allow roughly 6–10 weeks of build for a loft in Forest Hill, plus lead-in for design, Building Control and party-wall notices. In SE23 the notices are usually the long pole, not the construction. Buildaway serves them at the start so your programme is not held hostage to a neighbour's response window.
Do I need planning permission for a loft conversion in Forest Hill?
Sometimes. In Forest Hill, a rear dormer within volume limits can be permitted development, but the roofscape here is scrutinised and Lewisham Council takes a view on anything visible from the street. Leasehold properties in SE23 also need freeholder consent regardless of planning. Buildaway checks all three routes at feasibility.
What types of loft conversion do you offer in Forest Hill?
Rooflight, dormer, hip-to-gable and mansard - Buildaway builds all four in Forest Hill. The right answer for your SE23 roof depends on ridge height, the stair, and what Lewisham Council will consent. We establish that before proposing a design.
Do Buildaway handle both design and construction for Forest Hill lofts?
Both, on one contract. For Forest Hill clients Buildaway handles the drawings, the structural engineering, the consents and the build itself. That matters on SE23 lofts more than most jobs, because the design and the structure are the same conversation.
Are your loft specialists local to Forest Hill?
We are in Forest Hill constantly. Buildaway knows SE23 roof stock - the headroom you actually get, where the party wall sits, and how Lewisham Council treats dormers here. Local experience makes our feasibility answers reliable rather than optimistic.
