Kitchen Extensions: Where Layout Decisions Get Made Too Late
Common challenges
- Island placement that blocks natural circulation routes
- Glazing that floods the space with heat in summer
- Utility and storage squeezed out to prioritise the island
- Structural openings sized without considering the finished layout
- Kitchen designed before the extension shape is finalised
- Ventilation and extraction treated as an afterthought
How ArchEvolve solves them
- Circulation routes tested in 3D before committing to island placement
- Glazing specified with solar control and ventilation strategy in mind
- Utility and storage designed in from the earliest layout stage
- Structural openings sized around the intended kitchen layout
- Kitchen layout and extension shape designed together, not separately
- Kitchen layout and extension shape designed together, not separately

Kitchen Extension Design Across Sussex and Surrey
Many single storey kitchen extensions to the rear fall under permitted development, subject to size limits. Our guide to extension limits covers the current thresholds.
Costs depend on floor area, glazing specification and the kitchen fit-out itself, which is separate from the design and construction cost of the extension shell. See our house extension cost guide for the shell costs.
After the architectural layout is developed, ideally. ArchEvolve designs the room proportions, structural openings and glazing first, so your kitchen supplier can then design units that fit the space perfectly rather than compromising the architecture to fit standard unit widths.
Yes, this is one of the most requested outcomes. ArchEvolve designs structural openings and sightlines to connect the new kitchen extension with existing living and dining spaces, creating a genuinely open-plan ground floor.
It can, if the glazing specification and orientation are not properly considered. ArchEvolve factors solar control, ventilation and shading into the design from the concept stage to avoid this common problem.
The service covers feasibility assessment, 3D concept design focused on layout and light, planning application, full Building Regulations drawings, and construction drawings for your builder.
