"Excellent team and very helpful. Design spec answered all our questions very promptly even when we asked for things to be changed/amended it was completed really quickly. The fixed price included unlimited alterations to get the final result and exactly what we wanted. They guided us through all the different stages and explained the process very clearly. We can’t recommend Design Spec enough. Thank you to Dan and the team at Design Spec."

"Design Spec Ltd are fantastic. They have helped us through the design and planning of our bungalow renovation and extension and we could not be more grateful. They are quick at responding, patient and very professional. We would recommend this company to everyone going through this process!"

"We are completely inexperienced and had no idea where to start with getting our double storey extension plans off the ground. So grateful we found Design Spec. Wonderful team to work with; friendly, helpful, and very knowledgeable. Quick to acknowledge every query and provided pragmatic and honest advice. We had a huge delay getting our planning permission result from the council and am so grateful to Dan for incessantly chasing a response - completely took the stress and pressure from us (which was a huge relief as we have a newborn baby and couldn't have coped ourselves) and the plans passed first time. Excellent service and we are now moving forward with them for our building control approval. Looking forward to working with them again on the next stage of our project."

Chelmsford is on the rise – invest in your biggest asset, today

From July 2022 to June 23, house prices have risen at an average of 4.9%, and if it continues at this rate until 2025, the average house price will be £434,490. As the rate of new builds won’t increase dramatically, it is likely that existing homes will continue to rise in price in the long-term.

Renovating your property has always been considered a fool-proof way to grow its value, by adding space, optimising existing space and creating new rooms in the loft or garage. Some popular home renovations could add up to 6% onto the existing property of your home.
The Chelmsford area has become increasingly popular for workers commuting into London and other areas in Essex, and property prices have recovered strongly since 2022. As Greater London becomes more unaffordable, families and professionals are looking to set down roots in the Chelmsford area with its strong transport links and variety of amenities.

  • A kitchen renovation could add up to 6%
  • Renovating your bathroom can add £10,000.
  • Adding a driveway can add £10,000.
  • Renovating your garage into a room can add 20%.
  • Increasing your energy efficiency can add anywhere between 14% and 38% in some parts of the UK.

Our Chelmsford architects are well placed to make any change to your property due to their extensive experience of working in the area and with local homeowners. Our fixed fee architecture service is here to help you make the changes you want to your property.
