Historic Conversion & Refurbishment Works in Bromley, London & Kent

Breathing new life into period properties, residential homes, and commercial buildings with 50 years of family-run experience and expertise.

Whether adapting a historic heritage building for modern living or refurbishing a large-scale commercial building, navigating structural alterations requires a highly specialised approach. At Kellys’ Chartered Building Surveyors, we expertly manage the delicate balance between preserving historical integrity, maximising commercial asset value, and upgrading buildings to meet stringent modern standards of comfort, safety, and energy efficiency.

Operating from our base in Bromley, we provide expert architectural design, heritage planning, and rigorous project management for conversions and comprehensive refurbishments across London, Kent, and Sussex. We proudly serve a diverse client base, spanning private homeowners, commercial investors, Local Authorities, and Housing Associations.

Expertise Across Residential and Commercial Sectors

Over the past 50 years, the Practice has developed a formidable reputation across multiple sectors. Our extensive experience ensures we apply commercial-grade rigour to every project, regardless of size:

•    Commercial & Public Sector

We have built up a comprehensive level of experience providing services to Housing Associations, Local Authorities, and professional commercial clients. We manage projects across various types of tenure, ranging from basic rented sectors to highly specialised Shared Housing for Special Needs. We understand the strict financial and statutory demands of the commercial sector.

•    Private Residential & Heritage Conservation

We bring this same rigorous project management to the private sector. Whether we are converting redundant agricultural barns into high-end residential homes or sympathetically dividing period properties, our primary focus is strict architectural conservation. We meticulously preserve and showcase original features such as exposed structural oak timbers, vaulted ceilings, and traditional masonry while intelligently integrating the necessary insulation and services required to meet modern Building Regulations without compromising the building's historical narrative.

Advanced Design, Sustainability & BREEAM

We specialise in full architectural services utilising advanced Computer Aided Design (CAD). We do not simply refurbish a building for today; we design it for the long term.
With our commercial and residential design services, we ensure that any project complies with and is formally certified to the latest BREEAM (Building Research Establishment Environmental Assessment Method) standards. Beyond the immediate build, our comprehensive services extend to future planned maintenance, strict fire risk evaluation, energy conservation, Cost in Use, and Life Cycle Analysis.

The Danger of Standard Builders on Historic Homes

Older buildings, whether they are Victorian terraces, Georgian townhouses, or Listed rural barns, were constructed using traditional methods. They are designed to "breathe."
A common and highly expensive mistake is treating a historic residential refurbishment like a modern building project.

When standard builders apply modern, impermeable materials (such as cement renders or incorrect insulation) to period brickwork, it traps moisture, leading to severe dampness, timber decay, and structural failure.

With over 50 years of combined experience in building knowledge, we understand exactly how these buildings function. We specify the correct traditional materials (such as breathable lime mortars) alongside sympathetic modern technologies, ensuring your refurbishment protects the fundamental fabric and character of the building for generations to come.

Navigating Complex Heritage Legislation

Altering a period property involves navigating a maze of strict legal protections. You do not have to manage this bureaucratic process alone.

We act as your lead consultant, conducting the necessary historical research and liaising directly with Local Authority Conservation Officers. Whether your property is located within a designated Conservation Area or holds Grade II Listed Building status, we prepare and submit all specialised architectural drawings and applications required to secure formal Listed Building Consent and Planning Permission.

Project Management & Quality Assurance

Executing a historic conversion or major commercial refurbishment requires meticulous oversight. We offer highly adaptable services ranging from traditional pre- and post-contract roles to full Design and Contract Administration. We regularly evaluate tenders and monitor projects utilising Design and Build forms of contract, as well as Contract Administration for more traditional forms of contract.

To ensure absolute financial control and quality, our typical end-to-end services include:

1. Inception & Design

• Preparation of comprehensive feasibility reports and estimates.
• Providing professional cost advice and specific BREEAM advice.
• Executing Full Measured Surveys, architectural design services, and the preparation of detailed working CAD drawings.

2. Specification & Procurement

• Preparation of comprehensive, highly detailed Specifications of Work.
• Providing advice on the most appropriate type of contract to be used and the preparation of all contract documentation.

3. Financial Control & Site Monitoring

• Rigorously monitoring work on site and preparing regular Progress Reports.
• Exercising strict cost control, preparing valuations, and issuing financial statements during active building operations to ensure budgets are maintained.
• Agreeing on prices for variations with contractors and issuing the appropriate contract instructions.

4. Post-Contract & Maintenance

• Agreeing on the Contractor's final accounts.
• Monitoring repairs up to and including the completion of the Rectification Period (Defects Liability Period), ensuring the contractor fulfils all obligations.
• Establishing Term Maintenance contracts, monitoring these agreements, checking contractors' invoices, and accurately certifying payments.
• Preparing future Maintenance Reports and Schedules.

Frequently Asked Questions (FAQs)

Do I need special permission to refurbish a Listed Building?

Yes. If your property is Listed, it is a criminal offence to carry out any works that affect its character as a building of special architectural or historic interest without first obtaining Listed Building Consent. This applies to internal alterations just as strictly as external ones. We handle all of these complex applications on your behalf.

Why does my period property suffer from damp?

In many cases, damp in historic buildings is caused by previous, poorly executed refurbishments. The use of modern cement pointing, non-breathable paints, or the blocking of traditional ventilation traps moisture inside the walls. Our first step is always to diagnose the root cause of the damp and specify the correct, breathable repairs.

Can I make an old building energy efficient without losing its character?

Absolutely. While you may not be able to install standard cavity wall insulation, there are numerous highly effective, sympathetic methods to improve thermal performance. We can specify breathable internal wall insulation, draft-proofing measures, and secondary glazing systems that respect and preserve the historical fabric while significantly reducing your heating bills.
