Loft conversions
We design loft conversions that create additional living space within existing roof structures, with careful consideration given to layout, natural light, structure, and how new spaces integrate with the rest of the home. Each project is approached with a clear understanding of planning constraints, building regulations, and buildability from the outset.
Design
A successful loft conversion starts with intelligent design, not drawings rushed for planning.
Every roof space is different, structure, head height, access, party walls, and neighbouring properties all influence what is realistically achievable. Our role is to unlock the maximum potential of your loft while keeping the proposal proportionate, compliant, and buildable.
We focus on clean layouts, strong spatial logic, and natural light. Dormers, rooflights, or hip-to-gable extensions are considered carefully to ensure they sit comfortably within the existing building and surrounding context.
Good loft design should feel inevitable, as though it was always meant to be there.

Planning
Many loft conversions fall under permitted development, but this should never be assumed.
We assess your property against planning constraints such as conservation areas, Article 4 directions, volume allowances, roof form, and neighbouring impact. Where permitted development applies, we design within those limits to avoid unnecessary risk.
If planning permission is required, we prepare clear, policy-led proposals supported by accurate drawings and measured surveys. Our experience helps avoid common pitfalls that delay or derail applications.
The aim is always the same: a smooth route to approval with no surprises.
Build
We design loft conversions with construction in mind from day one.
Structural strategy, stair positioning, fire regulations, and access routes are resolved early to prevent costly redesigns later. This ensures the project can move efficiently from drawings to site.
We can work alongside your chosen builder or recommend experienced contractors where required. Detailed, well-coordinated drawings help keep pricing transparent and the build process controlled.
A well-designed loft should be straightforward to build, not a puzzle to solve on site.
Costs
Loft conversion costs vary depending on size, structure, roof form, and level of finish.
As a general guide, simple rooflight conversions are at the lower end of the scale, while dormer or hip-to-gable lofts require greater structural input and budget. Stair design, bathrooms, and insulation upgrades also influence overall cost.
We provide clear, fixed fees for our design services and help you understand where costs are being driven within the build itself. Early clarity allows informed decisions before money is committed.
Good decisions upfront protect your budget later.
A HOBBS ARC loft conversion adds space, value, and longevity, without compromising the character of your home.
