01 / The PRS market

There has been a surge of interest in the private rented sector (PRS) in recent years, prompting a growth in the development of institutionally backed and developer-led PRS accommodation in our towns and cities, which challenge traditional concepts of acceptable housing.

This emerging asset class represents an opportunity for investors, developers and local authorities to diversify and reduce risk across their property portfolios.

Key drivers
One of the major drivers of PRS growth has been the lack of housing availability and supply, particularly for first-time buyers, compounded by spiralling house prices in London, the South-east and other metropolitan areas. This has resulted in a sharp increase in the number of renters, with the proportion doubling (from 15% to 30%) in some locations and the average age of a first-time homebuyer in the UK pushed to almost 40. In London alone, one in four of those aged 25-35 still lives with their parents. Yet there is little consolation for renters, in London at least. Figures from January 2016 show that Londoners spend, on average, nearly two-thirds of their income on rent.

However, there are other issues to consider. Increasingly, employers are demanding flexibility from their workforce. The talent pool is now global. City-hopping professionals need to be responsive to the labour market, and so short, hassle-free tenures may well prove more viable than a long-term mortgage. Graduates will also have experienced good quality, purpose-built student accommodation during their studies. Realistically, few of them will be able to buy a home in the capital or other major cities, and so they will expect a high standard of rental accommodation as they embark on their professional careers.

Nothing new?
As an idea, PRS – large-scale developments with purpose built, private rented apartments – is not new. In the first half of the 20th century, the idea flourished, with projects such as Du Cane Court in Balham, south London becoming more prevalent. The art deco development offered 676 apartments with a range of amenities and was, at the time, the largest privately owned development in Europe. Since then, although becoming well-established in Europe, South-east Asia, the Middle East and North America, PRS has formed only a small part of the UK’s residential property market.

However, the UK government’s hopes to stimulate PRS as a way to unlock housing supply continue, namely through its Private Rented Sector Taskforce and the £1bn Build to Rent fund outlined in its Housing Strategy. Investors and developers are starting to demonstrate a preference for PRS schemes too, enabling them to avoid the intense sales and marketing activities associated with sales of individual units, instead developing an ongoing estate, offering steady, longer-term gains.

Think clearly
The opportunity around PRS may be substantial, but addressing the issues requires clear thinking. Quality is key – the reputation for poor standards that currently underpins the buy-to-let sector must be replaced with service, support and facilities equal to or surpassing those on offer in the market or comparable asset classes, such as the best student accommodation.

New delivery models may also be required. A joint venture that draws on a developer’s local market knowledge and expertise in overseeing delivery, backed up by an institutional investor’s equity support may be a strong proposition, reducing short-term risk and maintaining a return over a longer period. A local authority-developer model may also work well, combining asset ownership and planning knowledge with commercial expertise.

02 / PRS: What and where?

With PRS, one size does not fit all. Investors, developers and local authorities will need to oversee a range of typologies with considerable variation in design, capacity and style, to respond to local market demands.

Needs will vary according to demographics – from studio and one-bedroom apartments for recent graduates or young professionals, through to larger living spaces to support the increasing numbers of families moving into PRS. As the typical age of first-time buyers looks to increase, intergenerational communities may also become prevalent. The population may be ageing, but those older people still want to live in a mixed and vibrant community. Conversely, the opportunity to differentiate PRS according to lifestyle or age group also presents unique opportunities and introduces the “pull factor” associated with the congregation of similar social groups.

There will be an impact on planning. Schemes purpose-built for rent may be laid out to a different specification to those built for immediate sale. Authorities will need to be flexible with their adopted design standards. Similarly, design teams must acknowledge that amenity space and facilities will be major differentiators for potential tenants, potentially outweighing the investment in architecture or high-end fixtures that would be more standard in a for-sale model (although this remains an important factor, especially at the upper, “executive” end of PRS).

Yet there is no reason to doubt that PRS will continue to build momentum. Funding from the centre will help, with schemes like Build to Rent demonstrating the government’s keenness for PRS as a vehicle to help achieve housing demands.

Housing zones and regeneration
London will continue to attract PRS developments, prompted in part by the creation of 20 housing zones by the mayor of London in 2015, which are expected to deliver 50,000 more homes in total. And, while inner London has traditionally seen a larger number of private renters, investment interest is turning towards a “doughnut” clustered around zones 2, 3 and 4, buoyed by higher yields and good transport links into the centre.

Other areas of the UK offer good PRS potential too. The further 20 housing zones outside London identified in the March 2015 Budget will be a focus, thanks to central government funding to kickstart home building in brownfield sites. Regeneration areas such as the Greenwich Peninsula, Stratford, Lewisham Gateway and Croydon will see PRS as a positive way to bring new people into an area quickly. Major cities such as Manchester, Birmingham, Leeds and Glasgow will see significant PRS demand thanks to their vibrant economies and growth, which will be encouraged further by regional initiatives like the so-called “northern powerhouse”.

03 / Design

In any project, design and specification must be balanced against its ultimate viability, and PRS developments are no exception. In particular, operating and running costs will need to be included in the business case to ensure yields remain an incentive for investment.

Land costs will still be a major consideration. Aecom’s PRS cost model takes a typical development in London’s zone 2 / 3 as its starting point. Although not within prime inner London residential territory, these locations will be competitive, mainly due the combination of housing zone funding and good transport connectivity.

Tenant preferences should also be considered in the rental model. The opportunity cost for greater initial capital investment associated with enhanced specifications may not necessarily be recovered through yields, as tenants typically consider lower short-term rents preferable.

Design guides and differentiators
Ultimately, the price of land will influence the positioning of the final product in the rental market. To help mitigate these potentially high costs, and ensure continued take up, PRS developers need to identify differentiating factors at the design stage that make their product more appealing to end users.

The mayor of London’s Housing Design Guide (LHDG) will still be a touchstone for design teams, as well as any local authority design requirements. However, for PRS projects, amenities and communal areas will require more consideration. Amenity spaces, such as gyms, business areas, cafes and creches may be viewed more favourably by potential tenants. Areas that can be hired for private functions will also be popular, and communal outdoor spaces – roof gardens, green areas, quiet corners – will be important for families.

All of these are often perfunctory in developments created exclusively for sale. Taking time to think them through will pay dividends. Given that there are few current planning precedents or PRS-specific guidelines, discussion with local authority planning teams may be necessary.

Longevity
Given the potential diversity of the end-user tenant base, a mix of units will be necessary. Studios and one-bedroom apartments should be balanced with larger units designed for sharing or families. Maintenance should be minimal and straightforward. Design teams should look to standardise fixtures and fittings, enabling operators to keep a stock of key items. This will speed up repairs, reduce disruption to tenants and minimise the risk of potential void periods.

Within the units, the standard of finishes will be critical, but developers should not be tempted by super high-end fit-outs. Instead, select for quality and durability. Good warranty cover for ironmongery, sanitary ware and kitchen appliances is a must. Branding will play a crucial part in helping to create a specific PRS offer and the case for consistency of branding across materials and products, and the use of brand guidelines will help drive cost effective procurement.

In terms of MEP, fast broadband is crucial, as are IT points to main reception rooms. Broadband must work from day one, so routers and providers should be signed up to before tenants move in and then switched over to the tenant on occupation.

Functional areas are also important. Front and back of house spaces will be required for the estate management office, for maintenance and for storage space. Back of house should include dedicated routes for tenants to move in and out.

Even so, flexibility in design is also necessary. PRS developments may be given planning approval to allow units to be sold after a specified time, and so design teams should be mindful of this. The task is made easier by the degree of commonality in the occupational habits and behaviour of tenants and homeowners.

04 / Procurement and construction

Effective procurement and a first-class supply chain are the secret to getting PRS delivery right. Simple, straightforward procurement routes are important. Clear and easily understood risk transfers, with a process that selects a main contractor quickly once the tender has been returned and the supply chain soon after, will help achieve certainty.

Although the market continues to be constrained, there has been a potential softening with the realisation that pricing levels are becoming unsustainable from a viability perspective. The PRS market also presents clear opportunities for long-term partnering agreements with certain suppliers and trades, which will help keep costs reasonable and provide consistency in branding. Quality and repeatability are key when selecting these affiliations or supply chain agreements.

One- or two-stage tenders?
With two-stage tendering continuing to dominate main contractor procurement routes, this strategy remains preferential, for both PRS and for-sale models. Current wisdom is to keep first-stage tenders to a basic level, pricing only preliminaries, overheads and profit, contractor risk and programme. Developers may find contractors raising concerns about the second stages extending and delaying financial close.

There may be room for competitive, single-stage tendering, although contractors will favour a short and sweet process with, for example, a reduced number of contractors tendering, a reasonable tender period without tender addendums or additional design releases, and an obvious match with the contractor’s strengths and business plan.

Despite this, there still may be resistance from trades, especially the larger ones, many of whom prefer two-stage deals or preconstruction agreements for their initial bids. Some trades may only price jobs for contractors that have secured the main contract.

Construction
When it comes to construction, prevailing wisdom on major residential developments applies. On phased completions with early occupation, keeping “hard” construction activities physically separate is critical, from both a safety and a reputational perspective.

05 / Cost influences

The fundamental cost principles behind residential delivery, regardless of signature design or functionality, remain the same for PRS projects. Optimise the available area for tenants, with the right number of apartments per floor and the right size (or mix of sizes) for the apartments, supported by an effective building shape and core arrangement (including efficient wall-to-floor and net-to-gross ratios). Provide it for the right cost and complete construction in the quickest time, emphasising quality and repetition.

Specification
Adopting a similar approach to a residential for-sale development is a good yardstick, at least for the design and construction stages, although greater emphasis should be placed on communal and amenity areas. Comparing the net rentable area to the gross area is useful. The building’s efficiency will be affected by the amount of amenity space – while more amenity space means a less efficient building, good amenities may help attract a higher rental value.

The apartment types chosen will also affect cost. Studio and one-bedroom apartments offer the highest yield but cost more per square foot to build and fit out due to their obvious density. Other tenure types may be necessary to meet end-user demand, with a lower cost per square foot but lower yields too.

Apartment specification should also be planned carefully. Depending on the provider’s model, apartments may need to be fully furnished and kitted out, enabling tenants to take occupancy immediately on completion, instead of a more familiar shell and core / fit-out model. The “turnkey” approach will include furniture, fittings and equipment, down to crockery, cutlery, bed linen, TV and the like.

Operations and maintenance
There is, however, one major difference between for-sale and PRS cost estimates, and that is the importance of operations and maintenance to PRS schemes. Developers should consider adopting a whole lifecycle model that incorporates these stages, with operations teams (or operators, if they are different entities) involved early on.

There may be trade-offs. For example, improving the durability of developments – to reduce future maintenance and to create a quality product where people will want to live for decades to come – will increase upfront development costs.

In terms of procurement, furniture, fittings and equipment (FFE) and operations and service equipment (OSE) should form part of the project brief and procurement strategy. Operators may choose to adopt procurement models from other sectors, such as using specialist agents to source FFE and OSE from the international market and driving cost benefits from repetition and volume. This is largely dependent on the development and operational model adopted.

Alternatively, operators may choose to establish their own supply chain and use their own in-house management expertise. In any case, operators will be responsible for maintaining a good standard of service of the final asset, so durability, ease of replacement and longevity should be key factors.

Brand and marketing
While the aggressive sales strategies of for-sale schemes are rarely necessary in PRS schemes, some investment in marketing is required. Many tenants will hold relatively short leases, and so operators will need to attract a steady stream of new occupants to keep revenues flowing.

Creating and managing a credible brand is important. Key marketing messages should emphasise the quality of apartments, the range of amenities and the use of straightforward, flexible contracts. Peer marketing – via word of mouth within corporates who may use the same apartments for several tenants, or via social media for other groups – is becoming increasingly prevalent. A successful brand will also help to create momentum as investors and developers expand their offering to new cities or districts.

06 / Sustainability

Sustainability underpins all aspects of a PRS scheme. A development needs to be economically viable across its whole lifecycle, while minimising its environmental impact. And it can contribute to the creation of new communities and help regenerate others.

The whole lifecycle costing model will be important here too. Running costs, maintenance and replacements are just as important as construction costs. Service charges must be minimal, as they can only be recovered through rental costs.

In terms of construction, green building principles will be enshrined in local building regulations. These will generally follow, and improve upon the now-defunct Code for Sustainable Homes.

Innovation in “eco-friendly” design and construction can also be a useful marketing tool. Ideas such as the clever use of construction waste and low-energy technology should be investigated. Community-friendly initiatives work in the same way. Apprenticeships or local volunteering can build links with local people and help differentiate a scheme from competitors.

07 / Cost model

Aecom’s PRS cost model is based on 200 apartments located in zone 2 / 3 in London. The apartments are being built for PRS and are arranged in a single 11-storey building with two cores. Each core has its own apartment entrance lobby. The building also includes a residents’ gym (GIA 2,000 ft2), a private screening room and cinema (1,000ft2) and a residents’ lounge and multifunction area (2,000ft2), as well as a dedicated estate management suite (GIA of 1,500ft2) and two retail units (GIA 3,000ft2).

The building has a reinforced concrete frame with post-tensioned slab to maximise floor-to-ceiling heights. The external facade assumes 5% articulation and incorporates balconies to all apartments. The cladding is made up of a timber rainscreen with brickwork panels supported on a metsec / SFS backing system. Sanitary appliances and fittings have been selected for durability and ease of replacement with bathroom pods being provided to achieve the quality standards needed over the building’s lifecycle. Allowance has also been included for enhanced warranties for key items including kitchen fittings and appliances.

The gross internal floor area of the building is 165,390ft2 with a net-to-gross efficiency of 75% and a wall-to-floor ratio of 0.47. The rates are base dated at Q1 2016 and reflect prices obtained from a two-stage competitive tender, procured through design and build. The cost model excludes demolitions, any main contractor’s first stage or pre-construction fees, professional fees and contractor’s post-novation design fees. Also excluded are residential furniture, fittings and equipment (FFE) and operations and service equipment (OSE), Section 106/278 agreements and VAT.
