New Build & Structural Specialist Projects.
One Project Management Standard.
Every project type below is delivered under the same fixed-quote, single-contact Aspect process — from the first site visit to the final snag list.
House Extensions
Single and double-storey rear extensions, side-return extensions, wraparound extensions, and garden rooms. We handle the full build — from groundworks and structural steel to plastering, flooring, and decoration — giving you a seamless addition that feels like it was always there.
- Single-storey rear & side-return extensions
- Double-storey extensions & above-garage additions
- Orangeries, garden rooms & glazed extensions
- Permitted development and full planning applications
Loft Conversions
Converting your loft is the most cost-effective way to add a bedroom, home office, or studio without losing garden space. We assess your roof structure, advise on the right conversion type, and manage the full build including staircase, dormer windows, insulation, and party wall compliance.
- Dormer conversions (rear & side)
- Hip-to-gable & L-shaped dormers
- Mansard conversions
- Velux rooflight conversions (minimal structural change)
New Build Projects
Turnkey new build delivery for residential clients, plot developers, and self-builders across Bath and West Wiltshire. We coordinate every trade and discipline from groundworks and substructure through to fit-out, landscaping, and final handover — with weekly progress reports throughout.
- Detached & semi-detached new builds
- Plot development coordination
- Self-build project management
- Groundworks, drainage & substructure
Basement & Garage Conversions
Unlock below-ground space or transform an underused garage into a habitable room. Basement projects require specialist waterproofing and structural assessment — both of which are managed as standard within our scope. Garage conversions offer fast programme times with high value returns for family homes.
- Basement tanking & structural waterproofing
- Below-ground living space conversions
- Garage-to-room conversions (integral & detached)
- Structural steel & RSJ beam installations
Conservation Areas, Listed Buildings & Permitted Development
Bath is one of the most planning-sensitive cities in England. Any structural addition — even within permitted development limits — must respect the city's heritage character. We work closely with the BANES planning department and, where required, specialist heritage consultants to ensure your project is approved first time. We manage all pre-application enquiries, drawings coordination, and building regulations submissions as part of our service.
- Pre-application planning advice and BANES liaison
- Conservation area and Article 4 Direction compliance
- Listed Building Consent applications where required
- Party wall surveyor coordination and award management

Arrange a ConsultationStructural Builds FAQs
What counts as a structural build?
Anything that changes how a property's load is carried or adds a new structure entirely — house extensions, loft conversions, new builds, basement and garage conversions, and any wall removal that needs structural steel. If it needs Building Regulations sign-off, it's structural work in our terms.
Do you install structural steel (RSJs) for open-plan conversions?
Yes — RSJ and steel beam installation to remove load-bearing walls is one of our most common jobs, particularly for open-plan kitchen-diners in Victorian and Edwardian terraces. It's specified by a structural engineer, signed off by Building Control, and included in the fixed-price quote.
Can you build a new house from scratch?
Yes — full new build construction from groundworks and foundations through to completion, including plot assessment, planning management, and structural design. It's a smaller share of our work than extensions and conversions, but it's a core capability, not a one-off.
Do you handle basement and garage conversions?
Yes — both are structural conversions in their own right. Basement conversions need waterproofing (tanking) and structural underpinning assessed properly before work starts; garage conversions are usually more straightforward but still need Building Regulations compliance for insulation, damp-proofing, and often a change of use consideration.
Who signs off on structural work — do I need a structural engineer?
Yes, for anything load-bearing, and we arrange this as part of the project rather than leaving you to find one separately. The engineer's calculations go to Building Control for sign-off, which is what protects you (and any future buyer) when the work's eventually checked or the property's sold.
