For Architects and Designers

A specialist loft conversion partner for architects who want projects delivered properly, first time.

We're a local specialist team based in Sheffield, with over 80 years of combined experience in loft conversions and raised roof lifts across South Yorkshire. We know the property types, the common challenges, and how to get from drawing to finished space without surprises.

We're here to make your projects easier to deliver, whether you want us involved from feasibility or picking up a fully designed scheme and building it right. You don't need to change how you work. We fit around you.

Ways we can support you

Every architect works differently, and every project has different needs. We're set up to engage at whatever stage suits you.

Early design input

Want buildability advice before you commit to a scheme? We can join at feasibility stage to advise on structural approach, head heights, cost implications, and truss options. We know the homes around Sheffield and South Yorkshire, and that local knowledge helps us plan the details properly from the start.

Specification & costing

Already have a design? We can take your drawings and produce a detailed costed proposal with clear specification management, giving you and your client a full picture of what delivery looks like before anyone commits.

Full managed delivery

Hand over a project and know it will be built properly. A calm, managed process with clear scope, consistent updates, and a finish we're proud to put our name to. Your client won't be phoning you to ask what's happening.

Why architects come back to us

When you hand over a project, you need to know it'll be managed properly without dragging you back in. We've built a calm, managed process specifically for this.

In-house project system

Online client portal, documented decisions, tracked specifications, proactive updates. Clear scope from day one. Every project is managed, not just built.

Specialist experience

This is all we do. 80+ years combined experience, planned in detail, means we've seen what works, what causes problems, and how to avoid surprises.

Clear communication structure

Your client stays informed through our systems. You stay informed only when you need to be.

Finish quality

The new floor should feel like part of the original home. Light, layout, and proportions planned so the space works as a real room, not an afterthought.

When you recommend us, the process, communication, and finish quality speak for themselves.

The collaborative option

Where a client wants their architect involved throughout the build, we're set up to work as a three-way team. This isn't our default requirement, it's an option for projects where it adds value.

Architect

Design vision, planning, aesthetic decisions

Milestone

Buildability, programme, cost management, delivery

Client

Brief, budget, decisions, sign-off

Three roles, clearly defined. No overlap, no confusion, no one chasing anyone.
 

What we bring to your projects

Cost-conscious design

We think about how a design will actually be built: where walls land relative to structure, how windows align to reduce steelwork, where services run most efficiently. Good design and cost control aren't opposites. We can often achieve the same design outcome, the same light, layout, and proportions, with less complexity and lower cost.

Truss engineering

Access to leading UK truss designers. We can engineer replacement trusses for almost any roof structure, giving you confidence that complex raised roof lifts are achievable.

Project management

Online client portal, documented design specifications, tracked decisions, and a clear communication structure. Every project is managed, not just built.

Shell or turn-key

Flexible scope to match how the client wants to work. Whether you need a structural shell handed over to the home owner or your own fit-out team, or a fully managed turn-key delivery, we adapt to suit.

Professional project imagery

We provide high-quality drone and photographic images of the completed project, giving you polished visually for your portfolio, case studies, or planning submissions. No need to arrange your own photographer: we capture the finished result as standard.

Velux specialist

Fully certified Velux installer with over 20 years of window installation experience. We can advise on optimal window specification, placement, and integration during the design stage.
