“Working with design spec has been a pleasure. They offered much needed guidance at the early stages of the process. We needed ideas of what could and could not work for our roof extension. As we are looking to build a front dormer, the council will need to sign off our plans and during this processes Design Spec have been extremely informative and helpful, offering the professional expertise. I would highly recommend their services. Extremely responsive and polite.”

“Ben was recommended to us and proved to be the perfect choice of architect for the extension to our house which sits in an AONB landscape. From start to finish he was communicative, proactive, and came up with a beautifully sympathetic design. Our local community has complimented us on its seamless addition to the existing house, and we are delighted with the thoughtful use of space which has given us everything we wanted and more. Ben liaised with the council planning department, structural engineers, building control and builder, and has made the whole process as stress free as possible. We would highly recommend Ben’s services.”

The main types include rear extensions, side return extensions, wrap-around extensions, and double or single-storey extensions. More specific ones could be kitchen extensions, loft conversions, basement conversions, garage conversions or conservatories. Select the type that best suits your property and meets your space needs, if you are unsure, speaking with a local home extension builder in Southend-on-Sea.
