Our Aim

We work closely with our clients and Building control to make sure this happens, and, with each team concentrating on one contract at a time, you can be assured you have our undivided attention.


Surveys are arranged to suit you, daytime or evenings. Our surveyor, Dennis Graham, with just under 40 years experience managing, planning and building, will visit your home, discuss your requirements, and provide an estimate on the spot. Should you need drawings, he will leave paperwork that enables you to instruct DG Design Associates, (acting as an independent company) to prepare your drawings. They will be ready to view at your home within 14 days. Planning and Building Regulations Approval are applied for by DG Design on your behalf, including Structural Design too.  A one-stop shop that does it all, quickly and efficiently and acting as YOUR agent regardless of who you choose as your Construction Company.

Build options, We are in times of economic uncertainty, and we all want our money to go further. This has prompted us to restructure our business and create 3 new Build Options. As well as the traditional method where we do everything,  and you pay at the end, we have included a pay as you go option, a 1st fix option, and a DIY option.  Please click on the page tabs above for more information.

Construction times

A “Velux” Loft Conversion takes around 5 weeks, a “Dormer” is far more involved and can take up to 7 and a roof lift, hip to gable  or multi-roomed conversion around 8 weeks. Whichever design you choose, our main point of entry is always an external scaffold to keep the disturbance to a minimum. The staircase and fire doors are our last jobs to do before we leave.
