Work out what you want from the space

A successful loft conversion starts with a simple question: what does the new space need to achieve for your household? Think about how you will access it, how it connects to the rest of the home, and how you want it to feel in terms of light, privacy, and layout. Early conversations also help you avoid design work that pushes the project beyond budget.

Here at Maidenhead Planning, our approach centres on understanding your needs first, then developing options that suit your property and location. That early clarity gives the design stage direction and keeps decisions grounded.

Understand the planning route early

Many loft conversions can move forward under permitted development, but the rules are specific and vary depending on where you live and what you are proposing. Some homeowners choose a Certificate of Lawful Development for added reassurance, while others need a full planning application due to constraints such as listing, conservation considerations, flood risk, or greenbelt policies. 

Maidenhead Planning handle planning applications regularly and can advise on feasibility, likely constraints, and the smoothest route for approval. Starting the planning conversation now makes it easier to hit a 2026 timescale without rushed decisions.

Get drawings that builders can price properly

Once the concept is agreed, technical drawings become the foundation for accurate pricing and compliant construction. Builders need clear construction information to quote properly, and detailed drawings reduce the risk of budget drift later on. 

Maidenhead Planning can take concept or approved planning drawings and produce a comprehensive technical drawing set that considers building regulations requirements such as structural integrity, thermal performance, fire safety, acoustics, drainage, and electrical safety. They also coordinate with structural engineers and other specialists so the information is aligned and easy to follow on site.

Keep costs realistic from the beginning

Loft conversions involve choices that influence cost early, including structure, headroom solutions, stair positioning, and how services like drainage and electrics are routed. Having a professional guide at the start helps you make decisions with a view to feasibility and value for money. 

Maidenhead Planning charge an hourly fee with a fixed cost for the overall project, so you know exactly what you are committing to before work begins – handling measured surveys, planning drawings, applications, and building regulations drawings and approvals, depending on complexity.

Plan for a loft conversion in 2026

If you want one team to carry the project from design through to delivery, a design and build service can simplify communication and keep momentum. Maidenhead Planning can manage statutory approvals, building control, inspections, site meetings, materials, and contractor coordination, while keeping you updated on progress and decisions. 

If your loft conversion affects shared walls or involves building close to a neighbour, their building surveying services can also help with Party Wall procedures where required.
