Architecture. Planning. Technical Detail.

VIEW OUR PROJECTS

Architectural design, planning and technical detail

We take projects from first sketch to building site, handling planning, building regulations and the technical detail in between.

  • Rear, side and wraparound extensions, loft conversions and reconfigurations that make better use of your home.

  • Full planning, listed building consent and change of use, including sensitive sites in the High Weald AONB.

  • Bespoke homes, self-builds and small developments, from feasibility and planning through to completion.

  • Building regulations packages, construction drawings and coordination with engineers and consultants.

  • Shops, cafés, pubs and listed commercial buildings, designed around how the space is used.

  • Layouts, material palettes and finishes that tie the inside of a building to its architecture.

Client testimonials

  • Tom Gillespie

    Professional, efficient, reliable and at a very reasonable price

  • Joe Lamb

    What Jack doesn't know about the business isn't worth knowing. He's diligent, hard-working and supremely talented. He doesn't just tell you what you want to hear, which is almost unheard of in my experience. Highly recommend him and Studio on Sea

    Jack was a pleasure to work with from start to finish. This was my first house, so I had no idea where to start with an extension and Jack guided me throughout, including the planning process. He was always friendly, helpful and reassuring, making what could have been a stressful process very straightforward and easy. I wouldn't hesitate to recommend him.

    Professional and creative architectural design practice with great communication skills.

    We worked with Jack from Studio on Sea Ltd on our house extension project. He spent time with us to understand our brief, worked up approved concept drawings through to a successful planning application, coordinating with other specialists and obtaining competitive quotes where necessary along the way. Jack managed liaising with the planning team from the local council, which had its challenges, and kept us informed at every step of the process. It was a pleasure to work with him on our project and I’d recommend working with Studio On Sea without hesitation. Many thanks.

Many hurdles are over come to get to this stage; planning, building regulations, structural coordination, value engineering, detailed design, just to name a few.

WIP- on site. Conservation area. Always great to see our projects on site, meeting specialist consultants & discussing details. Can’t wait to see this one develop in the coming months. Jack was instrumental in improving the design of a planning permission that came with a plot to build a family home . He led us through design , multiple surveys , consultants required , planning application and managed to get all pre commencement conditions signed off with the approval notice thanks to building a great relationship with the planning officer . He also provided a detailed construction drawing package to aid a smooth construction . A one stop shop . Very easy to work with and excellent attention to detail . A very positive experience and we will use him again on future projects .  Edward Bowen .  #planning #construction #newbuild #development #details #wip #onsite #conservationarea #conservation #kent

We are delighted to receive planning permission for this contemporary extension in Hastings. The scheme creates an open plan, socially focussed space, making the most of natural light within the roof slopes. The scheme respects local scale & sits comfortably within its residential context. The palette of materials are detailed as such to create a simple but crisp addition. Looking forward to taking this through to technical design & assisting on site. #planning #planningconsent #planninggranted #hastings #hastingsarchitecture #design #extension #architecturaldesign #plan #openplan #openplanliving #periodoroperty
