Are you thinking of extending your living space into your roof space?


A loft conversion is an excellent way of adding space and value to your home.

A well designed loft conversion can add up to 20% to the value of your property.

John has successfully carried out planning work on well over 200 extension schemes many of which were loft conversions.

John has successfully carried out building regulation drawings and reports for extensions / alterations to existing buildings for well over 150 schemes many of which have been loft conversions

At Concept 20 we believe DETAIL IS KEY!

Our loft conversion building regulation drawing packages cover every element of the proposals in full detail above and beyond the minimum requirement to gain building regulation approval & we charge no additional fee for this extra level of detail.

Less queries from Building control as more aspects are covered with large scale drawings rather than notes

A more accurate quote from builders. Less assumptions will need to be made due to the extra information. There is far less chance of being surprised by additional building fees for 'Something that wasn't in the quote'

Much easier job for the Structural Engineer. I make sure to look at the structural design myself  & ask the structural engineer to justify my proposals, other architects usually leave all of the structural design to the engineer which costs you extra time and money.

Less queries from builders on site as to how an element of the building is to be constructed due to a higher amount of large scale construction details.

Despite the additional detail, our fee's are no higher than what a typical Architect would charge for building regulation drawings.

“I hired John to plan a loft conversion at my house. I had no experience doing this kind of thing before and he was amazing. He came round, discussed potential options and clearly explained how the process would work. His drawings for both planning and building regs were all very precisely detailed and he came up with some really creative ideas to utilise the space, while keeping costs down. Very professional, knowledgeable and easy to get along with, I would recommend his services to anyone and will definitely use him again myself for any future projects!”

John did the drawings and plans for our loft extension. I was incredibly impressed with his dedication to making sure all measurements were accurate, and details thorough, the drawings were second to none and absolutely gorgeous.
He was also really helpful and knowledgeable in regard to what was needed to meet planning permission and building regs, The drawings were incredibly personalised to meet our needs, as we didn’t want a typical dormer, but sash style windows that would let a lot of light in. John made sure to make maximum use of space, giving us as much window as possible while still meeting the requirements for planning. We are incredibly grateful for his personalised and creative approach. The extension is aesthetic and practical. Thank you so much John!
