Dormer loft conversion in a Hertfordshire home

Dormer loft conversions


Dormers designed for space and light

From flat-roof dormers to gabled extensions — we design and build dormers that feel integral to your home.

Every dormer begins with understanding your roof structure, planning constraints, and how you intend to use the new space. We develop designs that maximise headroom and daylight while respecting the character of your property.

Mansard loft conversion on a Hertfordshire property

Mansard loft conversions


Mansard extensions for maximum space

Rear mansard roof alterations that transform the upper storey — adding headroom, daylight, and architectural presence.

Mansard conversions suit properties where a dormer alone cannot deliver the floor area you need. We design mansard extensions that feel considered and proportionate, with careful attention to materials, windows, and roof detailing.

Velux roof light loft conversion in Hertfordshire

Velux & roof light conversions


Loft space unlocked with roof lights

Velux and roof light conversions that transform usable attic space — often within permitted development rights.

Where ridge height allows, a roof light conversion can be the most efficient route to an extra bedroom, study, or storage room. We assess your loft, specify the right roof windows, and deliver a finished space you can move into.

Hip-to-gable loft conversion in Hertfordshire

Hip-to-gable conversions


Hipped roofs opened for space

Hip-to-gable alterations combined with dormers or roof lights — the solution for homes where a standard loft conversion is not viable.

Properties with hipped roofs often lack the internal volume for a usable loft room. We extend the gable wall and reconfigure the roof to create the floor area and headroom your family needs.

Loft bedroom with en-suite in Hertfordshire

Loft bedrooms & en-suites


Bedrooms designed above the rest

Master suites and additional bedrooms in the loft — with en-suites, storage, and daylight carefully considered.

A loft bedroom should feel like a proper retreat, not an afterthought. We design layouts, en-suites, and storage solutions that make the most of your new upper-storey space.

Loft home office in a Hertfordshire property

Loft home offices


Workspaces designed above the noise

Loft home offices that give you a dedicated, quiet room for focused work — with daylight, connectivity, and proper insulation.

Working from home deserves better than the kitchen table. We design loft offices with acoustic separation, ample power and data, and natural light that keeps you productive throughout the day.

Structural steelwork during a loft conversion in Hertfordshire

Structural loft work


Structure engineered for your loft

Steel beams, floor strengthening, and roof alterations — the structural foundation every loft conversion depends on.

Loft conversions require serious structural work. We specify and install steel beams, reinforce floor joists, and manage roof alterations with engineering calculations and building control approval.

Planning & building regulations


Approvals managed from the start

Permitted development advice, planning applications, and building regulations — so your loft conversion is compliant before work begins.

Navigating planning and building regulations can be the most confusing part of a loft conversion. We advise on what approvals you need, prepare the drawings, and manage submissions and inspections on your behalf.
