— COMMERCIAL ARCHITECTURE —

Commercial and Change of Use

Projects involving multiple units or commercial property require a different level of planning awareness, technical detail, and coordination. Whether you’re converting a house into an HMO, creating self-contained flats, or changing the use of a commercial building, getting the drawings and permissions right from the start is critical.

At Get Rapid Plans Ltd, we support landlords, developers, investors, and business owners with planning drawings, building regulations drawings, and submission support for residential and commercial projects across London.

Change of Use

New Builds

HMOs

Shop Conversions

HMO Design & Planning Support

Houses in Multiple Occupation are subject to stricter planning and space standards, and requirements vary significantly between councils. Small mistakes at the design stage can lead to refusals, enforcement issues, or licensing problems later.

We help with:

  • HMO feasibility assessments

  • Space standards and room size layouts

  • Shared facilities planning

  • Compliance with local planning policies

  • Drawings to support HMO licence applications

 

Before progressing, we carry out a free feasibility and policy review, checking whether planning permission is required, whether Article 4 Directions apply, and what standards your local authority expects.

Flat Conversions & Multi-Unit Developments

Converting a property into flats requires careful planning around layout efficiency, access, fire safety, sound insulation, and waste storage — alongside planning policy considerations.

We prepare drawings for:

  • House-to-flat conversions

  • Subdivision of large dwellings

  • Self-contained studio and one-bed units

  • Small residential developments

Our designs aim to balance approval requirements with commercial viability, helping you maximise usable space while remaining compliant.

Where planning permission is required, we manage the submission process and respond to council feedback to keep your project moving.

Commercial & Change of Use Projects

Commercial planning applications often involve a change of use, alterations to shopfronts, or internal layout changes to meet building regulations. These projects require a clear understanding of planning use classes and local authority expectations.

We assist with:

  • Change of use applications

  • Shop and retail layout drawings

  • Office, mixed-use, and small commercial schemes

  • Planning and building control submissions

We assess the planning route early, highlight potential risks, and ensure drawings are prepared with both planning and construction in mind.

Planning Drawings & Submissions

Where required, we handle the full planning submission process, liaising with the local authority and keeping you informed at each stage.

We help with:

  • HMO feasibility assessments

  • Space standards and room size layouts

  • Shared facilities planning

  • Compliance with local planning policies

  • Drawings to support HMO licence applications

Before progressing, we carry out a free feasibility and policy review, checking whether planning permission is required, whether Article 4 Directions apply, and what standards your local authority expects.

Building Regulations Drawings – Clear & Construction-Ready

All HMO, flat conversion, and commercial projects require Building Regulations approval. We prepare detailed drawings that demonstrate compliance and provide contractors with clear information to build accurately.

Our support often extends into the construction phase, where we:

  • Clarify technical details

  • Provide additional drawings if needed

  • Assist builders and building control officers

This is particularly valuable on complex or multi-unit projects.

They gave me lots of good advice and helped me get approval on my application quickly and comparatively the quote was very reasonable.Dilnashin checked my property details over the phone and gave me a quote quickly, unlike past experience with others who took a long time and gave an expensive price which was quite a time waster.
