featured project _
an extension we designed in roundhay recently appeared in The Times. the kitchen at the middle of it, by Grid Thirteen, working inside the space we drew, has since been shortlisted for a national design award.
it's a good example of how we like to work: get the shell right, then give specialists like grid thirteen the room to do their best work inside it.

residential _
residential work is where we started and it's still most of what we do. before we draw anything we want to know how your household actually runs, who cooks, where the school bags land, why the current kitchen doesn't work. the design comes out of that.
we can take a project the whole way, feasibility, planning, technical drawings, then support while it's being built, or just the stages you need. either way it's andrew or jack on the phone, not a project manager you've never met.

google review · verified clientcommon questions _
Many single-storey rear extensions fall under permitted development, but it depends on the size, your property type and whether you are in a conservation area or near a listed building. We check exactly which route applies at the feasibility stage, before any drawings are done.
Architect fees depend on the construction value of the project and how many RIBA work stages you need. Our fee calculator gives an indicative figure in a couple of clicks, and we confirm a fixed fee after a free first visit.
Design and planning typically run three to six months, concept, drawings, then a roughly eight-week planning determination, with construction time on top. We give you a realistic timeline for your specific project at the outset.
Yes. Alongside extensions, renovations and loft conversions, we design one-off new-build houses on infill and self-build plots, drawn from scratch.
We are based in Morley, Leeds and work across West Yorkshire, North Yorkshire and Lincolnshire, including Roundhay, Alwoodley, Horsforth, Ilkley, Harrogate and Wetherby.
