We combine innovative design with quality construction and luxurious finishes. Each home is planned with lifestyle and wellbeing in mind, using natural light wherever possible to create a sense of calm.

Jigsaw

Founded in 2005 by Melissa Horne, Jigsaw is a close-knit team with offices in Poole and London, serving clients from multinationals to smaller niche developers across the South East, the M3 corridor, London and the Home Counties.

Their technical skills complement the design process: work is produced in 2D and 3D CAD to industry standards that contractors and suppliers can read and build from.

What we offer

One team, from site to finishes.

Every project is as unique as the land it is built on. We offer options tailored to each owner's needs, and our architects and interior designers handle the whole process — renovations, new construction and the specification of furnishings.

Architecture

Our architects combine a strong balance of technical and creative talent. Our core skills cover architecture and interiors, with specialist knowledge in sustainable design, commercial, healthcare and industrial projects. We deliver a full architectural service with integrated project management.

Interior design

Together with Jigsaw interior architects we design interiors around light, flow and everyday comfort, and specify finishes, joinery and furnishings to the same standard as the building itself.

Land planning & estate design

From site appraisal to the layout of a whole development, we shape each scheme around its setting and its neighbours. Visits to projects in progress or completed are available on request.
