Loft Conversions Built for Solihull Homes

A loft conversion is one of the most cost-effective ways to add a genuine extra bedroom or home office without extending your home's footprint — particularly valuable on the smaller plots common around Solihull town centre and Olton. We design and build dormer, hip-to-gable and mansard conversions, handling the staircase design, structural work, insulation and building regulations approval as one project.

Our team has worked across the borough, including a ground-up new build in Solihull featured in our portfolio, and we bring the same attention to structural detail to every loft conversion, whatever the roof type.

  • Dormer, hip-to-gable, mansard and rooflight conversions
  • Full building regulations sign-off included as standard
  • We handle Solihull MBC planning applications where required
  • 12-month workmanship guarantee, up to 5 years structurally

Why Choose HSS in Solihull

We know Solihull's roofscapes and which conversions typically need full planning.

Roof-Type Expertise

From the hipped roofs common on Solihull's 1930s semis to steeper Victorian pitches near the town centre, we design the conversion that suits your roof.

Design-and-Build, One Team

Architecture, structural engineering, staircase design and construction under one roof — no handoffs, no gaps in accountability.

Fully Accredited

Federation of Master Builders, Gas Safe, NICEIC and REFCOM certified, with structural guarantees on every project.

Planning Permission for Loft Conversions in Solihull

Most loft conversions in Solihull can be built under permitted development rights, without a full planning application — provided the additional roof space doesn't exceed 40 cubic metres for a terraced house, or 50 cubic metres for a semi-detached or detached house (including any previous roof extensions). Dormer windows generally need to be set back from the original eaves, and materials should match the existing house.

That allowance doesn't apply everywhere. Solihull has 20 conservation areas — including Knowle, Olton, Dorridge and Solihull town centre — where permitted development rights for roof extensions are removed, meaning a full application to Solihull Metropolitan Borough Council is required. We confirm your property's status before finalising a design.

Planning rules summarised here are for general guidance only and can change — we'll confirm exactly what applies to your specific property before any work begins.

Frequently Asked Questions

Often not — many loft conversions fall under permitted development if they stay within the volume limits (40m³ for a terraced house, 50m³ for a semi-detached or detached house) and don't extend beyond the roof plane at the front. Properties in one of Solihull's 20 conservation areas, including Knowle, Olton and Dorridge, need a full planning application regardless of size.
We design and build dormer, hip-to-gable, mansard and rooflight (Velux) conversions, choosing the option that suits your roof structure, head height and budget.
Yes — building regulations apply to every loft conversion regardless of planning permission, covering structural strength, fire safety (including escape routes), insulation and staircase access. We manage this sign-off as part of the project.
Most loft conversions take around 6–8 weeks on site once designs and any required approvals are in place, though this varies with roof type and scope.
